We look at the division of 786317 by 85 
We want to divide 786317 by 85.

Advancing to step 1:
The number 85 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 85

Going ahead to step 2:
When dividing 78 by 85, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Grab the next digit (6) from the dividend, add it to 78, then carry on: 786 / 85

Step 3:
85 goes into 786 9 times with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 765 from 786 to get 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 85

Advancing to step 4:
The number 85 fits into 213 2 times, leaving a remainder of 43.
Use 2 as the next digit of our solution. 
Result so far: 92.0
Subtracting 170 from 213 leaves us with 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 85

Advancing to step 5:
The number 85 fits into 431 5 times, leaving a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 925.0
If we take 425 away from 431, we end up with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 85

Step 6:
If we divide 67 by 85, we get 0 and a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 9250.0
Deduct 0 from 67 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 7:
The number 85 fits into 670 7 times, leaving a remainder of 75.
Put 7 as the next digit of the answer. 
Result so far: 9250.7
Subtracting 595 from 670 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.

Step 8:
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: 9250.78
If we subtract 680 from 750, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
85 can be fit into 700 8 times, resulting in a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 9250.788
The remainder is 20 after subtracting 680 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 9250.788 with a remainder of 0.002.
