Let's divide 646916 by 85
We want to divide 646916 by 85.

Going ahead to step 1:
6 divided by 85 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 85

Going ahead to step 2:
If we divide 64 by 85, we get 0 and a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Bring next digit (6) of the dividend behind the 64 and repeat the process: 646 / 85

On to step 3:
The number 85 fits into 646 7 times, leaving a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 595 away from 646, we end up with 51.
Fetch the next digit (9) from the dividend, attach it to 51 and continue: 519 / 85

Advancing to step 4:
85 can be fit into 519 6 times, resulting in a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
If we subtract 510 from 519, we get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 85

On to step 5:
When dividing 91 by 85, we get 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 761.0
If we subtract 85 from 91, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 85

Advancing to step 6:
66 divided by 85 is 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 7610.0
Subtract 0 from 66 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 7:
85 goes into 660 7 times with a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 7610.7
If we take 595 away from 660, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 8:
The number 85 fits into 650 7 times, leaving a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 7610.77
The remainder is 55 after subtracting 595 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 7610.77 with a remaining 0.055.
