We look at the division of 98766991 by 866 
We're looking to find how many times 866 goes into 98766991.

Moving on to step 1:
866 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 866

Step 2:
866 can be fit into 98 0 times, resulting in a remainder of 98.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 98 after subtracting 0 from 98.
Append the next digit (7) from the dividend to 98 and continue with: 987 / 866

Advancing to step 3:
If we divide 987 by 866, we get 1 and a remainder of 121.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 866 away from 987, we end up with 121.
Take the next digit (6) from the dividend and append it to 121, then repeat: 1216 / 866

Step 4:
866 goes into 1216 1 times with a remainder of 350.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 866 away from 1216, we end up with 350.
Append the next digit (6) from the dividend to 350 and continue with: 3506 / 866

Moving on to step 5:
866 goes into 3506 4 times with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 114.0
Subtract 3464 from 3506 to get 42.
Append the next digit (9) from the dividend to 42 and continue with: 429 / 866

Step 6:
429 divided by 866 is 0 with a remainder of 429.
Put 0 as the next digit of the answer. 
Result so far: 1140.0
Subtract 0 from 429 to get 429.
Include the next digit (9) from the dividend after 429, then repeat: 4299 / 866

Going ahead to step 7:
If we divide 4299 by 866, we get 4 and a remainder of 835.
The number 4 becomes the next digit in our result. 
Result so far: 11404.0
Subtracting 3464 from 4299 leaves us with 835.
Append the next digit (1) from the dividend to 835 and continue with: 8351 / 866

Let's proceed to step 8:
866 goes into 8351 9 times with a remainder of 557.
Write down 9 as next digit of the result. 
Result so far: 114049.0
Deduct 7794 from 8351 and we're left with 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Let's proceed to step 9:
866 goes into 5570 6 times with a remainder of 374.
The next digit of our result is 6. 
Result so far: 114049.6
If we take 5196 away from 5570, we end up with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Going ahead to step 10:
The number 866 fits into 3740 4 times, leaving a remainder of 276.
Record the quotient 4 as the next digit in the result. 
Result so far: 114049.64
Subtract 3464 from 3740 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 11:
If we divide 2760 by 866, we get 3 and a remainder of 162.
Write down 3 as next digit of the result. 
Result so far: 114049.643
If we subtract 2598 from 2760, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 12:
1620 divided by 866 is 1 with a remainder of 754.
Use 1 as the next digit of our solution. 
Result so far: 114049.6431
Subtracting 866 from 1620 leaves us with 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Step 13:
866 can be fit into 7540 8 times, resulting in a remainder of 612.
The number 8 becomes the next digit in our result. 
Result so far: 114049.64318
Deduct 6928 from 7540 and we're left with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Going ahead to step 14:
When dividing 6120 by 866, we get 7 with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 114049.643187
Subtract 6062 from 6120 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 15:
If we divide 580 by 866, we get 0 and a remainder of 580.
The next digit of our result is 0. 
Result so far: 114049.643187
The remainder is 580 after subtracting 0 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

On to step 16:
866 can be fit into 5800 6 times, resulting in a remainder of 604.
Record the quotient 6 as the next digit in the result. 
Result so far: 114049.64318706
Subtract 5196 from 5800 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.

In conclusion, the division gives 114049.64318706 with a balance of 6.04e-07.
