Let's divide 831586 by 72
We're looking to find how many times 72 goes into 831586.

On to step 1:
The number 72 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 72

Going ahead to step 2:
If we divide 83 by 72, we get 1 and a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
If we take 72 away from 83, we end up with 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 72

Advancing to step 3:
111 divided by 72 is 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 72 from 111 and we're left with 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 72

Let's proceed to step 4:
The number 72 fits into 395 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
Subtract 360 from 395 to get 35.
Fetch the next digit (8) from the dividend, attach it to 35 and continue: 358 / 72

Moving on to step 5:
The number 72 fits into 358 4 times, leaving a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 1154.0
Subtracting 288 from 358 leaves us with 70.
Append the next digit (6) from the dividend to 70 and continue with: 706 / 72

Going ahead to step 6:
The number 72 fits into 706 9 times, leaving a remainder of 58.
The next digit of our result is 9. 
Result so far: 11549.0
If we take 648 away from 706, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 7:
If we divide 580 by 72, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 11549.8
The remainder is 4 after subtracting 576 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
40 divided by 72 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 11549.8
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
400 divided by 72 is 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 11549.805
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
When dividing 400 by 72, we get 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 11549.8055
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 11549.8055, and the remainder is 0.0004.
