We're dividing 708772 by 21 
Let's see how many times 21 fits into 708772.

Let's proceed to step 1:
21 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 21

Step 2:
The number 21 fits into 70 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 63 from 70 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 21

Moving on to step 3:
21 goes into 78 3 times with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we take 63 away from 78, we end up with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 21

Advancing to step 4:
21 can be fit into 157 7 times, resulting in a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 337.0
The remainder is 10 after subtracting 147 from 157.
Fetch the next digit (7) from the dividend, attach it to 10 and continue: 107 / 21

Going ahead to step 5:
107 divided by 21 is 5 with a remainder of 2.
The next digit of our result is 5. 
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

Step 6:
22 divided by 21 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 33751.0
If we subtract 21 from 22, we 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.

Moving on to step 7:
10 divided by 21 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 33751.0
If we subtract 0 from 10, we 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.

Advancing to step 8:
100 divided by 21 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 33751.04
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
21 can be fit into 160 7 times, resulting in a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 33751.047
Deduct 147 from 160 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 10:
If we divide 130 by 21, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 33751.0476
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
When dividing 40 by 21, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 33751.04761
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 12:
190 divided by 21 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 33751.047619
If we subtract 189 from 190, we 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.

Advancing to step 13:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the 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:
21 goes into 100 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 33751.04761904
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 33751.04761904 with a remaining 1.6e-08.
