We look at the division of 89075533 by 990 
Let's see how many times 990 fits into 89075533.

Step 1:
If we divide 8 by 990, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 990

Going ahead to step 2:
990 goes into 89 0 times with a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 89, we end up with 89.
Append the next digit (0) from the dividend to 89 and continue with: 890 / 990

Let's proceed to step 3:
890 divided by 990 is 0 with a remainder of 890.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 890 leaves us with 890.
Bring next digit (7) of the dividend behind the 890 and repeat the process: 8907 / 990

Moving on to step 4:
When dividing 8907 by 990, we get 8 with a remainder of 987.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 7920 from 8907 to get 987.
Bring next digit (5) of the dividend behind the 987 and repeat the process: 9875 / 990

Step 5:
When dividing 9875 by 990, we get 9 with a remainder of 965.
Write down 9 as next digit of the result. 
Result so far: 89.0
Subtracting 8910 from 9875 leaves us with 965.
Grab the next digit (5) from the dividend, add it to 965, then carry on: 9655 / 990

Moving on to step 6:
If we divide 9655 by 990, we get 9 and a remainder of 745.
Use 9 as the next digit of our solution. 
Result so far: 899.0
If we take 8910 away from 9655, we end up with 745.
Append the next digit (3) from the dividend to 745 and continue with: 7453 / 990

Moving on to step 7:
The number 990 fits into 7453 7 times, leaving a remainder of 523.
The number 7 becomes the next digit in our result. 
Result so far: 8997.0
The remainder is 523 after subtracting 6930 from 7453.
Append the next digit (3) from the dividend to 523 and continue with: 5233 / 990

Moving on to step 8:
The number 990 fits into 5233 5 times, leaving a remainder of 283.
Use 5 as the next digit of our solution. 
Result so far: 89975.0
If we subtract 4950 from 5233, we get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Step 9:
990 goes into 2830 2 times with a remainder of 850.
The number 2 becomes the next digit in our result. 
Result so far: 89975.2
Subtract 1980 from 2830 to get 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

On to step 10:
990 can be fit into 8500 8 times, resulting in a remainder of 580.
Write down 8 as next digit of the result. 
Result so far: 89975.28
Subtract 7920 from 8500 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 11:
990 goes into 5800 5 times with a remainder of 850.
Use 5 as the next digit of our solution. 
Result so far: 89975.285
If we take 4950 away from 5800, we end up with 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

On to step 12:
990 can be fit into 8500 8 times, resulting in a remainder of 580.
Put 8 as the next digit of the answer. 
Result so far: 89975.2858
If we subtract 7920 from 8500, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 13:
If we divide 5800 by 990, we get 5 and a remainder of 850.
The number 5 becomes the next digit in our result. 
Result so far: 89975.28585
Subtracting 4950 from 5800 leaves us with 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

Moving on to step 14:
If we divide 8500 by 990, we get 8 and a remainder of 580.
Record the quotient 8 as the next digit in the result. 
Result so far: 89975.285858
If we take 7920 away from 8500, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 15:
990 goes into 5800 5 times with a remainder of 850.
Use 5 as the next digit of our solution. 
Result so far: 89975.2858585
Subtract 4950 from 5800 to get 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

Advancing to step 16:
990 goes into 8500 8 times with a remainder of 580.
Record the quotient 8 as the next digit in the result. 
Result so far: 89975.28585858
If we take 7920 away from 8500, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

The final result is 89975.28585858 with a remainder of 5.8e-07.
