On to step 3:
99 can be fit into 866 8 times, resulting in a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 792 from 866 and we're left with 74.
Append the next digit (9) from the dividend to 74 and continue with: 749 / 99

Step 4:
749 divided by 99 is 7 with a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
If we take 693 away from 749, we end up with 56.
Append the next digit (9) from the dividend to 56 and continue with: 569 / 99

Advancing to step 5:
When dividing 569 by 99, we get 5 with a remainder of 74.
The next digit of our result is 5. 
Result so far: 875.0
Subtracting 495 from 569 leaves us with 74.
Grab the next digit (0) from the dividend, add it to 74, then carry on: 740 / 99

Let's proceed to step 6:
The number 99 fits into 740 7 times, leaving a remainder of 47.
The next digit of our result is 7. 
Result so far: 8757.0
If we take 693 away from 740, we end up with 47.
Grab the next digit (8) from the dividend, add it to 47, then carry on: 478 / 99

Going ahead to step 7:
The number 99 fits into 478 4 times, leaving a remainder of 82.
The next digit of our result is 4. 
Result so far: 87574.0
Subtract 396 from 478 to get 82.
Take the next digit (9) from the dividend and append it to 82, then repeat: 829 / 99

Going ahead to step 8:
99 can be fit into 829 8 times, resulting in a remainder of 37.
The number 8 becomes the next digit in our result. 
Result so far: 875748.0
Subtracting 792 from 829 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 9:
When dividing 370 by 99, we get 3 with a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 875748.3
Subtract 297 from 370 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 10:
730 divided by 99 is 7 with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 875748.37
Subtracting 693 from 730 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 11:
The number 99 fits into 370 3 times, leaving a remainder of 73.
The next digit of our result is 3. 
Result so far: 875748.373
Subtracting 297 from 370 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 12:
99 goes into 730 7 times with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 875748.3737
If we subtract 693 from 730, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 13:
When dividing 370 by 99, we get 3 with a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 875748.37373
Subtracting 297 from 370 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 14:
If we divide 730 by 99, we get 7 and a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 875748.373737
Subtracting 693 from 730 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 15:
If we divide 370 by 99, we get 3 and a remainder of 73.
Use 3 as the next digit of our solution. 
Result so far: 875748.3737373
If we take 297 away from 370, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 16:
730 divided by 99 is 7 with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 875748.37373737
If we take 693 away from 730, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

After the division, we end up with 875748.37373737 and a remainder of 3.7e-08.
