We look at the division of 636153 by 72 
We want to divide 636153 by 72.

On to step 1:
The number 72 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 72

On to step 2:
72 can be fit into 63 0 times, resulting in a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Append the next digit (6) from the dividend to 63 and continue with: 636 / 72

Step 3:
If we divide 636 by 72, we get 8 and a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 576 from 636, we get 60.
Include the next digit (1) from the dividend after 60, then repeat: 601 / 72

Step 4:
When dividing 601 by 72, we get 8 with a remainder of 25.
The next digit of our result is 8. 
Result so far: 88.0
Deduct 576 from 601 and we're left with 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 72

Moving on to step 5:
255 divided by 72 is 3 with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 883.0
The remainder is 39 after subtracting 216 from 255.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 72

Moving on to step 6:
72 can be fit into 393 5 times, resulting in a remainder of 33.
Put 5 as the next digit of the answer. 
Result so far: 8835.0
If we subtract 360 from 393, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 7:
If we divide 330 by 72, we get 4 and a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 8835.4
The remainder is 42 after subtracting 288 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
If we divide 420 by 72, we get 5 and a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 8835.45
The remainder is 60 after subtracting 360 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
If we divide 600 by 72, we get 8 and a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 8835.458
If we take 576 away from 600, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
When dividing 240 by 72, we get 3 with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 8835.4583
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
If we divide 240 by 72, we get 3 and a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 8835.45833
Deduct 216 from 240 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 8835.45833 and a remainder of 2.4e-05.
