Answer 2

Answer:

Here we will show you step-by-step with detailed explanation how to calculate 21 divided by 2 using long division.

Before you continue, note that in the problem 21 divided by 2, the numbers are defined as follows:

21 = dividend

2 = divisor

Step-by-step explanation:

Step 1:

Start by setting it up with the divisor 2 on the left side and the dividend 21 on the right side like this:

             

   2 ⟌ 2 1  

Step 2:

The divisor (2) goes into the first digit of the dividend (2), 1 time(s). Therefore, put 1 on top:

       1    

   2 ⟌ 2 1  

Step 3:

Multiply the divisor by the result in the previous step (2 x 1 = 2) and write that answer below the dividend.

       1    

   2 ⟌ 2 1  

       2    

Step 4:

Subtract the result in the previous step from the first digit of the dividend (2 - 2 = 0) and write the answer below.

       1    

   2 ⟌ 2 1  

     - 2    

       0    

Step 5:

Move down the 2nd digit of the dividend (1) like this:

       1    

   2 ⟌ 2 1  

     - 2    

       0 1  

Step 6:

The divisor (2) goes into the bottom number (1), 0 time(s). Therefore, put 0 on top:

       1 0  

   2 ⟌ 2 1  

     - 2    

       0 1  

Step 7:

Multiply the divisor by the result in the previous step (2 x 0 = 0) and write that answer at the bottom:

       1 0  

   2 ⟌ 2 1  

     - 2    

       0 1  

        0  

Step 8:

Subtract the result in the previous step from the number written above it. (1 - 0 = 1) and write the answer at the bottom.

       1 0  

   2 ⟌ 2 1  

     - 2    

       0 1  

     -   0  

         1  

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 21 divided by 2 calculated using Long Division is:

10

1 Remainder
