We look at the division of 708772 by 21 
We want to figure out the number of times 708772 can be divided by 21.

Advancing to step 1:
7 divided by 21 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 21

Let's proceed to step 2:
70 divided by 21 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 63 from 70 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 21

Let's proceed to step 3:
If we divide 78 by 21, we get 3 and a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we take 63 away from 78, we end up with 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 21

Moving on to step 4:
157 divided by 21 is 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 337.0
Subtracting 147 from 157 leaves us with 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 21

Going ahead to step 5:
When dividing 107 by 21, we get 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 3375.0
If we subtract 105 from 107, we get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 21

Moving on to step 6:
22 divided by 21 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 33751.0
If we take 21 away from 22, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
When dividing 10 by 21, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 33751.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 21, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 33751.04
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
If we divide 160 by 21, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 33751.047
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 10:
21 goes into 130 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 33751.0476
If we take 126 away from 130, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 33751.04761
If we take 21 away from 40, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 12:
21 goes into 190 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 33751.047619
Subtract 189 from 190 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
21 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 33751.047619
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
When dividing 100 by 21, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 33751.04761904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 33751.04761904 with a remainder of 1.6e-08.
