Let's divide 713636 by 21
We want to divide 713636 by 21.

On to step 1:
When dividing 7 by 21, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 21

Step 2:
71 divided by 21 is 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 63 from 71, we get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 21

Let's proceed to step 3:
The number 21 fits into 83 3 times, leaving a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 33.0
Deduct 63 from 83 and we're left with 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 21

On to step 4:
The number 21 fits into 206 9 times, leaving a remainder of 17.
The next digit of our result is 9. 
Result so far: 339.0
Subtract 189 from 206 to get 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 21

Going ahead to step 5:
173 divided by 21 is 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 3398.0
If we subtract 168 from 173, we get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 21

Going ahead to step 6:
When dividing 56 by 21, we get 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 33982.0
Subtracting 42 from 56 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
21 can be fit into 140 6 times, resulting in a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 33982.6
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
When dividing 140 by 21, we get 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 33982.66
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 33982.66 with a remainder of 0.014.
