85099557 ÷ 863 
We want to figure out the number of times 85099557 can be divided by 863.

Moving on to step 1:
If we divide 8 by 863, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 863

Step 2:
85 divided by 863 is 0 with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Fetch the next digit (0) from the dividend, attach it to 85 and continue: 850 / 863

Moving on to step 3:
When dividing 850 by 863, we get 0 with a remainder of 850.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 850 and we're left with 850.
Include the next digit (9) from the dividend after 850, then repeat: 8509 / 863

Let's proceed to step 4:
8509 divided by 863 is 9 with a remainder of 742.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 7767 from 8509, we get 742.
Grab the next digit (9) from the dividend, add it to 742, then carry on: 7429 / 863

On to step 5:
If we divide 7429 by 863, we get 8 and a remainder of 525.
Use 8 as the next digit of our solution. 
Result so far: 98.0
If we subtract 6904 from 7429, we get 525.
Bring next digit (5) of the dividend behind the 525 and repeat the process: 5255 / 863

Going ahead to step 6:
The number 863 fits into 5255 6 times, leaving a remainder of 77.
The number 6 becomes the next digit in our result. 
Result so far: 986.0
Subtracting 5178 from 5255 leaves us with 77.
Grab the next digit (5) from the dividend, add it to 77, then carry on: 775 / 863

Going ahead to step 7:
When dividing 775 by 863, we get 0 with a remainder of 775.
Use 0 as the next digit of our solution. 
Result so far: 9860.0
Subtract 0 from 775 to get 775.
Bring next digit (7) of the dividend behind the 775 and repeat the process: 7757 / 863

Going ahead to step 8:
7757 divided by 863 is 8 with a remainder of 853.
Put 8 as the next digit of the answer. 
Result so far: 98608.0
If we take 6904 away from 7757, we end up with 853.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8530, and continue the process.

Moving on to step 9:
If we divide 8530 by 863, we get 9 and a remainder of 763.
Write down 9 as next digit of the result. 
Result so far: 98608.9
Subtracting 7767 from 8530 leaves us with 763.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7630, and continue the process.

Let's proceed to step 10:
863 goes into 7630 8 times with a remainder of 726.
Write down 8 as next digit of the result. 
Result so far: 98608.98
If we take 6904 away from 7630, we end up with 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Advancing to step 11:
7260 divided by 863 is 8 with a remainder of 356.
Put 8 as the next digit of the answer. 
Result so far: 98608.988
Subtract 6904 from 7260 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Our division results in 98608.988 with a remaining 0.0356.
