647398 divided by 85 
We want to figure out the number of times 647398 can be divided by 85.

Step 1:
6 divided by 85 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 85

Moving on to step 2:
85 can be fit into 64 0 times, resulting in a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Take the next digit (7) from the dividend and append it to 64, then repeat: 647 / 85

On to step 3:
If we divide 647 by 85, we get 7 and a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 595 from 647 leaves us with 52.
Fetch the next digit (3) from the dividend, attach it to 52 and continue: 523 / 85

On to step 4:
523 divided by 85 is 6 with a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
The remainder is 13 after subtracting 510 from 523.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 85

Moving on to step 5:
The number 85 fits into 139 1 times, leaving a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 761.0
If we take 85 away from 139, we end up with 54.
Grab the next digit (8) from the dividend, add it to 54, then carry on: 548 / 85

Going ahead to step 6:
If we divide 548 by 85, we get 6 and a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 7616.0
Subtract 510 from 548 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
If we divide 380 by 85, we get 4 and a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 7616.4
Deduct 340 from 380 and we're left 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 8:
85 goes into 400 4 times with a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 7616.44
If we subtract 340 from 400, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 7616.44 with a remainder of 0.06.
