We divide 81165086 by 766
We want to divide 81165086 by 766.

Moving on to step 1:
If we divide 8 by 766, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 766

Step 2:
81 divided by 766 is 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Grab the next digit (1) from the dividend, add it to 81, then carry on: 811 / 766

On to step 3:
If we divide 811 by 766, we get 1 and a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 45 after subtracting 766 from 811.
Take the next digit (6) from the dividend and append it to 45, then repeat: 456 / 766

On to step 4:
766 goes into 456 0 times with a remainder of 456.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 456, we end up with 456.
Append the next digit (5) from the dividend to 456 and continue with: 4565 / 766

Moving on to step 5:
If we divide 4565 by 766, we get 5 and a remainder of 735.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
Subtracting 3830 from 4565 leaves us with 735.
Fetch the next digit (0) from the dividend, attach it to 735 and continue: 7350 / 766

On to step 6:
The number 766 fits into 7350 9 times, leaving a remainder of 456.
The number 9 becomes the next digit in our result. 
Result so far: 1059.0
Subtract 6894 from 7350 to get 456.
Take the next digit (8) from the dividend and append it to 456, then repeat: 4568 / 766

Step 7:
4568 divided by 766 is 5 with a remainder of 738.
Record the quotient 5 as the next digit in the result. 
Result so far: 10595.0
If we take 3830 away from 4568, we end up with 738.
Append the next digit (6) from the dividend to 738 and continue with: 7386 / 766

Going ahead to step 8:
If we divide 7386 by 766, we get 9 and a remainder of 492.
Put 9 as the next digit of the answer. 
Result so far: 105959.0
Deduct 6894 from 7386 and we're left with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Advancing to step 9:
4920 divided by 766 is 6 with a remainder of 324.
Write down 6 as next digit of the result. 
Result so far: 105959.6
The remainder is 324 after subtracting 4596 from 4920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 10:
3240 divided by 766 is 4 with a remainder of 176.
Put 4 as the next digit of the answer. 
Result so far: 105959.64
If we subtract 3064 from 3240, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 11:
766 goes into 1760 2 times with a remainder of 228.
The number 2 becomes the next digit in our result. 
Result so far: 105959.642
If we subtract 1532 from 1760, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

On to step 12:
766 can be fit into 2280 2 times, resulting in a remainder of 748.
The number 2 becomes the next digit in our result. 
Result so far: 105959.6422
Subtract 1532 from 2280 to get 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

After the division, we end up with 105959.6422 and a remainder of 0.00748.
