We look at the division of 979674 by 21 
Let's see how many times 21 fits into 979674.

On to step 1:
The number 21 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 21

Moving on to step 2:
If we divide 97 by 21, we get 4 and a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 84 from 97 and we're left with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 21

Let's proceed to step 3:
The number 21 fits into 139 6 times, leaving a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 46.0
If we take 126 away from 139, we end up with 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 21

Advancing to step 4:
21 can be fit into 136 6 times, resulting in a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 466.0
Deduct 126 from 136 and we're left with 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 21

Moving on to step 5:
When dividing 107 by 21, we get 5 with a remainder of 2.
The next digit of our result is 5. 
Result so far: 4665.0
If we subtract 105 from 107, we get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 21

Going ahead to step 6:
21 can be fit into 24 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 46651.0
If we take 21 away from 24, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
The number 21 fits into 30 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 46651.1
Subtract 21 from 30 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 8:
If we divide 90 by 21, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 46651.14
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
21 goes into 60 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 46651.142
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
If we divide 180 by 21, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 46651.1428
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
21 can be fit into 120 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 46651.14285
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 46651.142857
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
30 divided by 21 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 46651.1428571
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 14:
When dividing 90 by 21, we get 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 46651.14285714
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 46651.14285714 and a remainder of 6e-09.
