We look at the division of 632366 by 21 
We want to divide 632366 by 21.

On to step 1:
When dividing 6 by 21, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 21

Moving on to step 2:
63 divided by 21 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 63 from 63, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 21

Going ahead to step 3:
When dividing 2 by 21, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtract 0 from 2 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 21

Going ahead to step 4:
21 can be fit into 23 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 301.0
If we take 21 away from 23, we end up with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 21

Step 5:
When dividing 26 by 21, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 3011.0
The remainder is 5 after subtracting 21 from 26.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 21

On to step 6:
When dividing 56 by 21, we get 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 30112.0
Deduct 42 from 56 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.

Advancing to step 7:
If we divide 140 by 21, we get 6 and a remainder of 14.
The next digit of our result is 6. 
Result so far: 30112.6
Subtract 126 from 140 to get 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 8:
140 divided by 21 is 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 30112.66
If we subtract 126 from 140, we get 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 30112.66 with a remainder of 0.014.
