We divide 866831 by 72
We want to divide 866831 by 72.

Let's proceed to step 1:
8 divided by 72 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 72

On to step 2:
The number 72 fits into 86 1 times, leaving a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 72 from 86 to get 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 72

Moving on to step 3:
146 divided by 72 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 144 from 146 leaves us with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 72

Let's proceed to step 4:
When dividing 28 by 72, we get 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 120.0
If we subtract 0 from 28, we get 28.
Bring next digit (3) of the dividend behind the 28 and repeat the process: 283 / 72

Advancing to step 5:
The number 72 fits into 283 3 times, leaving a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 1203.0
Deduct 216 from 283 and we're left with 67.
Fetch the next digit (1) from the dividend, attach it to 67 and continue: 671 / 72

On to step 6:
72 can be fit into 671 9 times, resulting in a remainder of 23.
The next digit of our result is 9. 
Result so far: 12039.0
If we subtract 648 from 671, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
72 goes into 230 3 times with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 12039.3
If we subtract 216 from 230, 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.

Going ahead to step 8:
140 divided by 72 is 1 with a remainder of 68.
The next digit of our result is 1. 
Result so far: 12039.31
Subtracting 72 from 140 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 9:
The number 72 fits into 680 9 times, leaving a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 12039.319
If we subtract 648 from 680, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
The number 72 fits into 320 4 times, leaving a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 12039.3194
Subtracting 288 from 320 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
72 can be fit into 320 4 times, resulting in a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 12039.31944
Subtract 288 from 320 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 12039.31944, with a leftover of 3.2e-05.
