Let's divide 668871 by 85
We're looking to find how many times 85 goes into 668871.

Step 1:
85 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 85

Advancing to step 2:
66 divided by 85 is 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Fetch the next digit (8) from the dividend, attach it to 66 and continue: 668 / 85

Let's proceed to step 3:
85 goes into 668 7 times with a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 595 away from 668, we end up with 73.
Take the next digit (8) from the dividend and append it to 73, then repeat: 738 / 85

Moving on to step 4:
If we divide 738 by 85, we get 8 and a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Deduct 680 from 738 and we're left with 58.
Include the next digit (7) from the dividend after 58, then repeat: 587 / 85

Moving on to step 5:
When dividing 587 by 85, we get 6 with a remainder of 77.
The number 6 becomes the next digit in our result. 
Result so far: 786.0
Subtract 510 from 587 to get 77.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 85

Advancing to step 6:
771 divided by 85 is 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 7869.0
The remainder is 6 after subtracting 765 from 771.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
85 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 7869.0
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
600 divided by 85 is 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 7869.07
If we subtract 595 from 600, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
85 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 7869.07
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
500 divided by 85 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 7869.0705
If we subtract 425 from 500, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 11:
If we divide 750 by 85, we get 8 and a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 7869.07058
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.

Moving on to step 12:
If we divide 700 by 85, we get 8 and a remainder of 20.
The next digit of our result is 8. 
Result so far: 7869.070588
Subtracting 680 from 700 leaves us with 20.
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 outcome is 7869.070588, with a leftover of 2e-06.
