Perform The Division: $4 \longdiv {108}$.
=====================================================
Introduction
Long division is a mathematical operation that involves dividing a large number by a smaller number. It is a crucial concept in mathematics, and understanding how to perform long division is essential for solving complex problems in various fields, including algebra, geometry, and calculus. In this article, we will focus on performing the division: $4 \longdiv {108}$.
Understanding the Problem
Before we dive into the solution, let's break down the problem and understand what is being asked. We are given a dividend of 108 and a divisor of 4. Our goal is to find the quotient, which is the result of dividing the dividend by the divisor.
Step 1: Write the Dividend and Divisor
To start the long division process, we need to write the dividend and divisor in the correct format. The dividend is the number being divided, which is 108 in this case. The divisor is the number by which we are dividing, which is 4.
____________________
4 | 108
Step 2: Divide the First Digit
The next step is to divide the first digit of the dividend by the divisor. In this case, we will divide 1 (the first digit of 108) by 4.
____________________
4 | 108
- 4
Step 3: Multiply and Subtract
After dividing the first digit, we need to multiply the result by the divisor and subtract the product from the dividend. In this case, we will multiply 4 (the result of the division) by 4 (the divisor) and subtract the product from 108.

Step 4: Bring Down the Next Digit
Since we have a remainder of 8, we need to bring down the next digit of the dividend. In this case, we will bring down the 0.

80
Step 5: Repeat the Process
We will repeat the process of dividing the first digit of the dividend by the divisor, multiplying the result by the divisor, and subtracting the product from the dividend.

16
Step 6: Write the Quotient
After repeating the process, we will have a remainder of 16. Since we cannot divide 16 by 4, we will write the quotient and remainder.

Quotient: 27
Remainder: 0
Conclusion
In this article, we performed the division: $4 \longdiv {108}$. We broke down the problem into smaller steps, wrote the dividend and divisor in the correct format, divided the first digit, multiplied and subtracted, brought down the next digit, repeated the process, and wrote the quotient and remainder. The final answer is 27 with a remainder of 0.
