Dividing 4000 by 12: A Comprehensive Guide

Introduction

Division is a fundamental mathematical operation that plays a crucial role in various aspects of our daily lives. Understanding how to perform division accurately and efficiently is essential for solving real-world problems. This article provides a detailed explanation of the division process, with a specific focus on dividing 4000 by 12.

Understanding Division

Division is the opposite operation of multiplication. It involves finding the number of times a divisor (the number by which we are dividing) can fit into the dividend (the number we are dividing). In this case, we are dividing 4000 by 12, which means we are trying to determine how many times 12 can be subtracted from 4000.

Step-by-Step Division

To divide 4000 by 12, we can use the following step-by-step approach:

1. Set up the division problem:

      12 ) 4000

2. Find the largest multiple of 12 that fits into 4000:

Since 12 * 333 = 3996, which is the closest multiple of 12 to 4000, we write 333 above the line.

     12 ) 4000
          333

3. Subtract the multiple from the dividend:

   - 3996
        4

4. Bring down the next digit of the dividend:

     12 ) 4000
          333
   - 3996
        40

5. Repeat steps 2-4:

The largest multiple of 12 that fits into 40 is 3, so we write 3 above the line.

     12 ) 4000
          333
   - 3996
        40
          36

6. Subtract the multiple from the dividend:

   - 36
        4

7. Bring down the next digit of the dividend:

     12 ) 4000
          333
   - 3996
        40
          36
        - 4

8. Repeat steps 2-4:

The largest multiple of 12 that fits into 4 is 0, so we write 0 above the line.

     12 ) 4000
          333
   - 3996
        40
          36
        - 4
          0

9. Subtract the multiple from the dividend:

   - 0
        0

10. Check the answer:

Since we have no remainder, 4000 divided by 12 is 333.

     12 ) 4000
          333
   - 3996
        40
          36
        - 4
          0
