86998885 divided by 766 
Let's see how many times 766 fits into 86998885.

Going ahead to step 1:
8 divided by 766 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 766

Let's proceed to step 2:
The number 766 fits into 86 0 times, leaving a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Include the next digit (9) from the dividend after 86, then repeat: 869 / 766

Going ahead to step 3:
766 goes into 869 1 times with a remainder of 103.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 766 from 869, we get 103.
Bring next digit (9) of the dividend behind the 103 and repeat the process: 1039 / 766

Step 4:
766 goes into 1039 1 times with a remainder of 273.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 766 away from 1039, we end up with 273.
Bring next digit (8) of the dividend behind the 273 and repeat the process: 2738 / 766

On to step 5:
766 goes into 2738 3 times with a remainder of 440.
The next digit of our result is 3. 
Result so far: 113.0
The remainder is 440 after subtracting 2298 from 2738.
Include the next digit (8) from the dividend after 440, then repeat: 4408 / 766

Step 6:
766 can be fit into 4408 5 times, resulting in a remainder of 578.
The next digit of our result is 5. 
Result so far: 1135.0
Subtracting 3830 from 4408 leaves us with 578.
Bring next digit (8) of the dividend behind the 578 and repeat the process: 5788 / 766

On to step 7:
If we divide 5788 by 766, we get 7 and a remainder of 426.
Write down 7 as next digit of the result. 
Result so far: 11357.0
Deduct 5362 from 5788 and we're left with 426.
Fetch the next digit (5) from the dividend, attach it to 426 and continue: 4265 / 766

Going ahead to step 8:
The number 766 fits into 4265 5 times, leaving a remainder of 435.
Record the quotient 5 as the next digit in the result. 
Result so far: 113575.0
Subtracting 3830 from 4265 leaves us with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Going ahead to step 9:
766 goes into 4350 5 times with a remainder of 520.
The next digit of our result is 5. 
Result so far: 113575.5
Deduct 3830 from 4350 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 10:
766 goes into 5200 6 times with a remainder of 604.
The number 6 becomes the next digit in our result. 
Result so far: 113575.56
Subtract 4596 from 5200 to get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Moving on to step 11:
If we divide 6040 by 766, we get 7 and a remainder of 678.
Use 7 as the next digit of our solution. 
Result so far: 113575.567
Deduct 5362 from 6040 and we're left with 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Going ahead to step 12:
The number 766 fits into 6780 8 times, leaving a remainder of 652.
The number 8 becomes the next digit in our result. 
Result so far: 113575.5678
The remainder is 652 after subtracting 6128 from 6780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Advancing to step 13:
The number 766 fits into 6520 8 times, leaving a remainder of 392.
Record the quotient 8 as the next digit in the result. 
Result so far: 113575.56788
Subtracting 6128 from 6520 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

In conclusion, the division gives 113575.56788 with a balance of 0.000392.
