Understanding the Basics
Division is a fundamental operation in mathematics that involves splitting a number into equal parts. It is essential to grasp the basics of division to solve equations and perform various calculations. Let’s delve into the key concepts and principles of division.
Definition of Division
Division is the process of dividing a number, known as the dividend, by another number, called the divisor, to obtain the quotient. The quotient represents the number of times the divisor can be divided into the dividend evenly.
Explanation of Dividend and Divisor
The dividend is the number that is being divided, while the divisor is the number by which the dividend is divided. For example, in the equation 75 ÷ 11, 75 is the dividend, and 11 is the divisor.
How Division Works in Mathematics
To understand division, it is crucial to comprehend the concept of equal sharing. Division is essentially the process of dividing a quantity into equal parts. For instance, if you have 10 cookies and you want to distribute them equally among 2 friends, you would divide the total number of cookies (dividend) by the number of friends (divisor). In this case, each friend would receive 5 cookies.
Mathematically, division can be represented using the division symbol (÷) or a forward slash (/). The quotient is obtained by dividing the dividend by the divisor. In the example 75 ÷ 11, the quotient is the result of dividing 75 by 11.
Understanding the basics of division is essential for solving equations and performing mathematical calculations. Division involves dividing a number (dividend) by another number (divisor) to obtain the quotient. It is crucial to grasp the concept of equal sharing and how division works in mathematics. In the next section, we will explore the step-by-step process of solving division equations and introduce the long division method.
Breaking Down the Equation
Understanding how to break down an equation is crucial in solving mathematical problems. In this section, we will delve into the process of breaking down the equation 75 ÷ 11 and explore the step-by-step process of solving it.
Explanation of the Equation: 75 ÷ 11
Before we dive into the solution, let’s first understand the equation at hand. The equation 75 ÷ 11 represents the division of 75 by 11. In division, the number being divided is called the dividend, while the number we divide by is called the divisor.
Step-by-Step Process of Solving the Equation
To solve the equation 75 ÷ 11, we will employ the long division method. This method allows us to break down the division process into smaller, more manageable steps.
Begin by dividing the first digit of the dividend (7) by the divisor (11). Since 7 is smaller than 11, we move to the next digit, making the quotient 0.
Bring down the next digit of the dividend (5) and append it to the previous quotient (0). This gives us 05.
Now, divide 05 by 11. The quotient is 0 again, as 05 is still smaller than 11.
Bring down the last digit of the dividend (5) and append it to the previous quotient (00). This gives us 005.
Divide 005 by 11. The quotient is 0 once more, as 005 is still smaller than 11.
Finally, bring down the last digit of the dividend (5) and append it to the previous quotient (000). This gives us 0005.
Divide 0005 by 11. The quotient is 0 yet again, as 0005 is still smaller than 11.
At this point, we have exhausted all the digits of the dividend. The final quotient is 0000, and the remainder is 5.
The long division method is a systematic approach to solving division problems. It allows us to break down complex equations into smaller, more manageable steps. By following this method, we can ensure accuracy and obtain the correct quotient and remainder.
The long division method is particularly useful when dealing with larger numbers or when the divisor does not evenly divide the dividend. It provides a structured approach that simplifies the division process and makes it easier to understand.
In conclusion, breaking down an equation is a fundamental step in solving division problems. By employing the long division method, we can systematically solve equations and obtain accurate results. Understanding this process is essential for mastering division and applying it to real-life situations. In the next section, we will explore the interpretation of the result and its significance.

In this section, we will explore the process of solving a division equation step-by-step, using the example of 75 ÷ 11.
Dividing 75 by 11 using long division
Long division is a method used to solve division equations. It involves breaking down the dividend (the number being divided) and the divisor (the number by which we divide) into smaller parts to find the quotient (the result of the division) and the remainder (the amount left over).
To solve 75 ÷ 11 using long division, we start by dividing the first digit of the dividend (7) by the divisor (11). Since 7 is smaller than 11, we bring down the next digit (5) and divide it by 11. The result is 0, as 5 is smaller than 11.
Next, we bring down the next digit (5) and divide it by 11. The result is 4, as 44 is the largest multiple of 11 that is less than or equal to 55. We subtract 44 from 55, leaving us with a remainder of 11.
Finally, we bring down the last digit (0) and divide it by 11. The result is 0, as 0 is smaller than 11. We have now divided the entire dividend and obtained the quotient and remainder.
Demonstrating the process visually
To better understand the process, let’s visualize it using a table:
| Step | Dividend | Divisor | Quotient | Remainder |
|---|---|---|---|---|
| 1 | 75 | 11 | 0 | |
| 2 | 55 | 11 | 5 | |
| 3 | 44 | 11 | 4 | |
| 4 | 0 | 11 | 0 |
As we can see, the process involves dividing each digit of the dividend by the divisor and subtracting the multiples of the divisor from the dividend until there is nothing left to divide.
Identifying the quotient and remainder
In the example of 75 ÷ 11, the quotient is 5, and the remainder is 0. The quotient represents the number of times the divisor can be evenly divided into the dividend, while the remainder represents the amount left over.
It is important to note that not all division equations result in a remainder of 0. In some cases, there may be a remainder, indicating that the division is not exact. The remainder provides valuable information about the relationship between the dividend and the divisor.

Defining the Quotient and Remainder
In division, the quotient refers to the whole number obtained when the dividend is divided by the divisor. It represents the number of times the divisor can be subtracted from the dividend without resulting in a negative value. The quotient provides information about the relative size or quantity of the dividend in relation to the divisor.
On the other hand, the remainder is the amount left over after the division process is complete. It represents the part of the dividend that cannot be evenly divided by the divisor. The remainder is always less than the divisor and indicates the fractional or incomplete part of the division.
Explaining the Significance of the Quotient
The quotient obtained from a division equation holds great significance. It provides valuable information about the relationship between the dividend and the divisor. The quotient can help determine the number of equal parts the dividend can be divided into, each being the size of the divisor.
For example, if we divide 75 by 11, the quotient would be 6. This means that 75 can be divided into 6 equal parts, each being 11 in size. Understanding the quotient allows us to comprehend the relative magnitude or quantity of the dividend in terms of the divisor.
Understanding the Role of the Remainder
While the quotient provides information about the whole parts of the division, the remainder represents the fractional or incomplete part. It indicates the amount left over after dividing the dividend by the divisor as many times as possible.
In the case of 75 ÷ 11, the remainder would be 9. This means that after dividing 75 by 11 as much as possible, there is a remaining value of 9 that cannot be divided further. The remainder is crucial in understanding the completeness of the division process and identifying any leftover amount.
