We divide 840971 by 85
We want to figure out the number of times 840971 can be divided by 85.

Going ahead to step 1:
If we divide 8 by 85, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 85

Going ahead to step 2:
84 divided by 85 is 0 with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Fetch the next digit (0) from the dividend, attach it to 84 and continue: 840 / 85

Advancing to step 3:
When dividing 840 by 85, we get 9 with a remainder of 75.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 765 from 840 to get 75.
Include the next digit (9) from the dividend after 75, then repeat: 759 / 85

On to step 4:
If we divide 759 by 85, we get 8 and a remainder of 79.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
If we take 680 away from 759, we end up with 79.
Take the next digit (7) from the dividend and append it to 79, then repeat: 797 / 85

Going ahead to step 5:
85 goes into 797 9 times with a remainder of 32.
The next digit of our result is 9. 
Result so far: 989.0
The remainder is 32 after subtracting 765 from 797.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 85

Let's proceed to step 6:
85 can be fit into 321 3 times, resulting in a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 9893.0
Subtract 255 from 321 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.

On to step 7:
The number 85 fits into 660 7 times, leaving a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 9893.7
If we subtract 595 from 660, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 8:
When dividing 650 by 85, we get 7 with a remainder of 55.
Record the quotient 7 as the next digit in the result. 
Result so far: 9893.77
Subtracting 595 from 650 leaves us with 55.
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 9893.77 with a remaining 0.055.
