When it comes to division, there are different methods to solve an equation. Column division is one of them, and it is commonly used for large numbers or when the numbers do not evenly divide.

Column division is a process that involves dividing the number in the dividend by the divisor, starting from the left digit of the dividend. Here are the steps on how to do division:

Step 1: Write the dividend and divisor

Start by writing the dividend on top of the division symbol and the divisor below it. Make sure that the divisor is placed on the right side of the division symbol.

For example, if you have to solve 728 ÷ 4 using column-in-microsoft-excel” title=”How to Add a Column in Microsoft Excel”>column division, write 728 on the top and 4 below it. The equation should look like this:

182
┌───────
4 │ 728

Step 2: Divide the first digit

Start by dividing the first digit of the dividend by the divisor. In this example, you have to divide 7 by 4. Since 4 does not go into 7, you have to carry over the 7 to the next digit, making it 72.

182
┌───────
4 │ 728
-____

1
┌───────
4 │ 728
-____
4

Step 3: Multiply and subtract

Multiply the divisor by the quotient you obtained in the previous step.

In this example, the quotient is 1, and the divisor is 4. So, multiply 1 and 4, which equals 4, and write it under the 72. Then, subtract 4 from 7, which is equal to 3. Put the remainder 3 below the next digit, making it 38.

182
┌───────
4 │ 728
– 4
__
3

Step 4: Repeat the process

Repeat the process of dividing, multiplying, and subtracting until you have solved the entire equation. In this example, you have to divide 38 by 4, which equals 9. Multiply 4 by 9, and write 36 under 38. Then, subtract 36 from 38, which is equal to 2, and put the remainder 2 below the next digit, making it 28.

182
┌───────
4 │ 728
– 4
__
3
4 │ 38
│ -__
│ 36
│ __
│ 2

Repeat the process for the next digit, 28. You have to divide 28 by 4, which equals 7. Multiply 4 by 7, and write 28 under 28. Then, subtract 28 from 28, which is equal to 0, and there is no remainder.

182
┌───────
4 │ 728
– 4
__
3
4 │ 38
│ -__
│ 36
│ __
│ 2
└────
0

Step 5: Add the quotient

Add the quotient you obtained in each step to get the final answer.

In this example, the quotient is 1, 9, 7, and 7. So, the final answer is 182.

182
┌───────
4 │ 728
– 4
__
3
4 │ 38
│ -__
│ 36
│ __
│ 2
└────
0
—
182

Conclusion

Column division is a useful method to solve division equations with large numbers or numbers that do not evenly divide. By following these steps, you can solve any equation using the column division method. Practice makes perfect, and with enough practice, you can master this method and solve equations with ease.
