We divide 823791 by 85
We want to figure out the number of times 823791 can be divided by 85.

On to step 1:
If we divide 8 by 85, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 85

Going ahead to step 2:
The number 85 fits into 82 0 times, leaving a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 82, we get 82.
Bring next digit (3) of the dividend behind the 82 and repeat the process: 823 / 85

Advancing to step 3:
823 divided by 85 is 9 with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 765 from 823 and we're left with 58.
Include the next digit (7) from the dividend after 58, then repeat: 587 / 85

Let's proceed to step 4:
587 divided by 85 is 6 with a remainder of 77.
Put 6 as the next digit of the answer. 
Result so far: 96.0
Deduct 510 from 587 and we're left with 77.
Include the next digit (9) from the dividend after 77, then repeat: 779 / 85

Moving on to step 5:
When dividing 779 by 85, we get 9 with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 969.0
Deduct 765 from 779 and we're left with 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 85

On to step 6:
85 goes into 141 1 times with a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 9691.0
Subtracting 85 from 141 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 7:
When dividing 560 by 85, we get 6 with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 9691.6
The remainder is 50 after subtracting 510 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
The number 85 fits into 500 5 times, leaving a remainder of 75.
The next digit of our result is 5. 
Result so far: 9691.65
Subtracting 425 from 500 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 9:
85 can be fit into 750 8 times, resulting in a remainder of 70.
The next digit of our result is 8. 
Result so far: 9691.658
Deduct 680 from 750 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
The number 85 fits into 700 8 times, leaving a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 9691.6588
If we subtract 680 from 700, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 9691.6588 with a remaining 0.0002.
