We look at the division of 851577 by 72 
Let's see how many times 72 fits into 851577.

On to step 1:
72 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 72

Going ahead to step 2:
The number 72 fits into 85 1 times, leaving a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 72 from 85 leaves us with 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 72

Advancing to step 3:
72 goes into 131 1 times with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 72 from 131 leaves us with 59.
Append the next digit (5) from the dividend to 59 and continue with: 595 / 72

Advancing to step 4:
595 divided by 72 is 8 with a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 118.0
Deduct 576 from 595 and we're left with 19.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 72

On to step 5:
72 goes into 197 2 times with a remainder of 53.
The next digit of our result is 2. 
Result so far: 1182.0
The remainder is 53 after subtracting 144 from 197.
Grab the next digit (7) from the dividend, add it to 53, then carry on: 537 / 72

Advancing to step 6:
72 goes into 537 7 times with a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 11827.0
The remainder is 33 after subtracting 504 from 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
The number 72 fits into 330 4 times, leaving a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 11827.4
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.

Moving on to step 8:
72 can be fit into 420 5 times, resulting in a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 11827.45
If we take 360 away from 420, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
72 can be fit into 600 8 times, resulting in a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 11827.458
Subtract 576 from 600 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.

Advancing to step 10:
When dividing 240 by 72, we get 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 11827.4583
Subtracting 216 from 240 leaves us 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.

Going ahead to step 11:
If we divide 240 by 72, we get 3 and a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 11827.45833
The remainder is 24 after subtracting 216 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 11827.45833 with a remaining 2.4e-05.
