We look at the division of 706131 by 21 
We're looking to find how many times 21 goes into 706131.

Advancing to step 1:
When dividing 7 by 21, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 21

On to step 2:
If we divide 70 by 21, we get 3 and a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 63 from 70 and we're left with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 21

Moving on to step 3:
When dividing 76 by 21, we get 3 with a remainder of 13.
The next digit of our result is 3. 
Result so far: 33.0
Subtracting 63 from 76 leaves us with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 21

Going ahead to step 4:
If we divide 131 by 21, we get 6 and a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 336.0
If we subtract 126 from 131, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 21

Going ahead to step 5:
When dividing 53 by 21, we get 2 with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 3362.0
The remainder is 11 after subtracting 42 from 53.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 21

Advancing to step 6:
The number 21 fits into 111 5 times, leaving a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 33625.0
The remainder is 6 after subtracting 105 from 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 33625.2
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
21 goes into 180 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 33625.28
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
21 can be fit into 120 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 33625.285
If we take 105 away from 120, we end up with 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 10:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 33625.2857
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 11:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 33625.28571
The remainder is 9 after subtracting 21 from 30.
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 12:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 33625.285714
Subtract 84 from 90 to 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.

Going ahead to step 13:
21 goes into 60 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 33625.2857142
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 14:
The number 21 fits into 180 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 33625.28571428
Subtract 168 from 180 to 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.

The quotient of the division is 33625.28571428, and the remainder is 1.2e-08.
