We divide 8563108 by 866
Our goal is to divide 8563108 by 866.

On to step 1:
If we divide 8 by 866, 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.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 866

Moving on to step 2:
When dividing 85 by 866, we get 0 with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Include the next digit (6) from the dividend after 85, then repeat: 856 / 866

Moving on to step 3:
856 divided by 866 is 0 with a remainder of 856.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 856 and we're left with 856.
Grab the next digit (3) from the dividend, add it to 856, then carry on: 8563 / 866

Moving on to step 4:
If we divide 8563 by 866, we get 9 and a remainder of 769.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 7794 from 8563 leaves us with 769.
Include the next digit (1) from the dividend after 769, then repeat: 7691 / 866

Advancing to step 5:
866 goes into 7691 8 times with a remainder of 763.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
If we take 6928 away from 7691, we end up with 763.
Fetch the next digit (0) from the dividend, attach it to 763 and continue: 7630 / 866

On to step 6:
866 goes into 7630 8 times with a remainder of 702.
The next digit of our result is 8. 
Result so far: 988.0
If we subtract 6928 from 7630, we get 702.
Fetch the next digit (8) from the dividend, attach it to 702 and continue: 7028 / 866

Going ahead to step 7:
866 can be fit into 7028 8 times, resulting in a remainder of 100.
Use 8 as the next digit of our solution. 
Result so far: 9888.0
If we take 6928 away from 7028, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 8:
866 can be fit into 1000 1 times, resulting in a remainder of 134.
Use 1 as the next digit of our solution. 
Result so far: 9888.1
If we subtract 866 from 1000, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 9:
866 can be fit into 1340 1 times, resulting in a remainder of 474.
The number 1 becomes the next digit in our result. 
Result so far: 9888.11
Subtract 866 from 1340 to get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Our division results in 9888.11 with a remaining 0.474.
