We look at the division of 81566560 by 993 
We want to divide 81566560 by 993.

Moving on to step 1:
993 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 993

Advancing to step 2:
993 goes into 81 0 times with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Fetch the next digit (5) from the dividend, attach it to 81 and continue: 815 / 993

Step 3:
993 can be fit into 815 0 times, resulting in a remainder of 815.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 815 after subtracting 0 from 815.
Append the next digit (6) from the dividend to 815 and continue with: 8156 / 993

Step 4:
8156 divided by 993 is 8 with a remainder of 212.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 7944 from 8156 to get 212.
Grab the next digit (6) from the dividend, add it to 212, then carry on: 2126 / 993

Let's proceed to step 5:
If we divide 2126 by 993, we get 2 and a remainder of 140.
Put 2 as the next digit of the answer. 
Result so far: 82.0
If we subtract 1986 from 2126, we get 140.
Take the next digit (5) from the dividend and append it to 140, then repeat: 1405 / 993

On to step 6:
993 goes into 1405 1 times with a remainder of 412.
Put 1 as the next digit of the answer. 
Result so far: 821.0
Deduct 993 from 1405 and we're left with 412.
Bring next digit (6) of the dividend behind the 412 and repeat the process: 4126 / 993

Advancing to step 7:
993 goes into 4126 4 times with a remainder of 154.
Use 4 as the next digit of our solution. 
Result so far: 8214.0
Subtracting 3972 from 4126 leaves us with 154.
Include the next digit (0) from the dividend after 154, then repeat: 1540 / 993

Step 8:
If we divide 1540 by 993, we get 1 and a remainder of 547.
The number 1 becomes the next digit in our result. 
Result so far: 82141.0
Subtract 993 from 1540 to get 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Going ahead to step 9:
993 goes into 5470 5 times with a remainder of 505.
The next digit of our result is 5. 
Result so far: 82141.5
Deduct 4965 from 5470 and we're left with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Moving on to step 10:
5050 divided by 993 is 5 with a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 82141.55
Subtract 4965 from 5050 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

After the division, we end up with 82141.55 and a remainder of 0.085.
