Let's divide 87086930 by 866
We want to figure out the number of times 87086930 can be divided by 866.

Advancing to step 1:
866 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
Subtracting 0 from 8 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 866

Step 2:
866 can be fit into 87 0 times, resulting in a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Bring next digit (0) of the dividend behind the 87 and repeat the process: 870 / 866

Step 3:
The number 866 fits into 870 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 866 away from 870, we end up with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 866

Going ahead to step 4:
48 divided by 866 is 0 with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 48 and we're left with 48.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 866

On to step 5:
866 can be fit into 486 0 times, resulting in a remainder of 486.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Subtracting 0 from 486 leaves us with 486.
Append the next digit (9) from the dividend to 486 and continue with: 4869 / 866

Moving on to step 6:
4869 divided by 866 is 5 with a remainder of 539.
Use 5 as the next digit of our solution. 
Result so far: 1005.0
Subtract 4330 from 4869 to get 539.
Append the next digit (3) from the dividend to 539 and continue with: 5393 / 866

On to step 7:
When dividing 5393 by 866, we get 6 with a remainder of 197.
Record the quotient 6 as the next digit in the result. 
Result so far: 10056.0
If we take 5196 away from 5393, we end up with 197.
Include the next digit (0) from the dividend after 197, then repeat: 1970 / 866

Advancing to step 8:
866 goes into 1970 2 times with a remainder of 238.
Write down 2 as next digit of the result. 
Result so far: 100562.0
Deduct 1732 from 1970 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 9:
The number 866 fits into 2380 2 times, leaving a remainder of 648.
Record the quotient 2 as the next digit in the result. 
Result so far: 100562.2
Subtracting 1732 from 2380 leaves us with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

On to step 10:
The number 866 fits into 6480 7 times, leaving a remainder of 418.
Write down 7 as next digit of the result. 
Result so far: 100562.27
The remainder is 418 after subtracting 6062 from 6480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Step 11:
4180 divided by 866 is 4 with a remainder of 716.
The number 4 becomes the next digit in our result. 
Result so far: 100562.274
Subtract 3464 from 4180 to get 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

On to step 12:
7160 divided by 866 is 8 with a remainder of 232.
The number 8 becomes the next digit in our result. 
Result so far: 100562.2748
Deduct 6928 from 7160 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 13:
The number 866 fits into 2320 2 times, leaving a remainder of 588.
The next digit of our result is 2. 
Result so far: 100562.27482
Subtracting 1732 from 2320 leaves us with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Moving on to step 14:
866 can be fit into 5880 6 times, resulting in a remainder of 684.
Put 6 as the next digit of the answer. 
Result so far: 100562.274826
The remainder is 684 after subtracting 5196 from 5880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

On to step 15:
The number 866 fits into 6840 7 times, leaving a remainder of 778.
The next digit of our result is 7. 
Result so far: 100562.2748267
Subtract 6062 from 6840 to get 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

Moving on to step 16:
If we divide 7780 by 866, we get 8 and a remainder of 852.
The number 8 becomes the next digit in our result. 
Result so far: 100562.27482678
Subtracting 6928 from 7780 leaves us with 852.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8520, and continue the process.

In conclusion, the division gives 100562.27482678 with a balance of 8.52e-07.
