We look at the division of 90681760 by 99 
Let's see how many times 99 fits into 90681760.

Going ahead to step 1:
The number 99 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 99

Step 2:
The number 99 fits into 90 0 times, leaving a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Append the next digit (6) from the dividend to 90 and continue with: 906 / 99

Let's proceed to step 3:
When dividing 906 by 99, we get 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 891 away from 906, we end up with 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 99

On to step 4:
158 divided by 99 is 1 with a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 91.0
If we subtract 99 from 158, we get 59.
Append the next digit (1) from the dividend to 59 and continue with: 591 / 99

Step 5:
If we divide 591 by 99, we get 5 and a remainder of 96.
Use 5 as the next digit of our solution. 
Result so far: 915.0
If we take 495 away from 591, we end up with 96.
Take the next digit (7) from the dividend and append it to 96, then repeat: 967 / 99

On to step 6:
If we divide 967 by 99, we get 9 and a remainder of 76.
The next digit of our result is 9. 
Result so far: 9159.0
If we subtract 891 from 967, we get 76.
Include the next digit (6) from the dividend after 76, then repeat: 766 / 99

Going ahead to step 7:
If we divide 766 by 99, we get 7 and a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 91597.0
Subtracting 693 from 766 leaves us with 73.
Bring next digit (0) of the dividend behind the 73 and repeat the process: 730 / 99

Let's proceed to step 8:
99 can be fit into 730 7 times, resulting in a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 915977.0
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.

Let's proceed to step 9:
If we divide 370 by 99, we get 3 and a remainder of 73.
The next digit of our result is 3. 
Result so far: 915977.3
Deduct 297 from 370 and we're left 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.

On to step 10:
If we divide 730 by 99, we get 7 and a remainder of 37.
The next digit of our result is 7. 
Result so far: 915977.37
Deduct 693 from 730 and we're left 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.

Step 11:
When dividing 370 by 99, we get 3 with a remainder of 73.
Write down 3 as next digit of the result. 
Result so far: 915977.373
Deduct 297 from 370 and we're left 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 12:
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: 915977.3737
Subtract 693 from 730 to 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.

Moving on to step 13:
The number 99 fits into 370 3 times, leaving a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 915977.37373
Deduct 297 from 370 and we're left 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.

On to step 14:
99 can be fit into 730 7 times, resulting in a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 915977.373737
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 15:
99 goes into 370 3 times with a remainder of 73.
Put 3 as the next digit of the answer. 
Result so far: 915977.3737373
If we subtract 297 from 370, we 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.

Step 16:
When dividing 730 by 99, we get 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 915977.37373737
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.

After the division, we end up with 915977.37373737 and a remainder of 3.7e-08.
