We divide 988775 by 90
We're looking to find how many times 90 goes into 988775.

Going ahead to step 1:
If we divide 9 by 90, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 90

Advancing to step 2:
98 divided by 90 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 90 from 98 leaves us with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 90

Let's proceed to step 3:
When dividing 88 by 90, we get 0 with a remainder of 88.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 88 leaves us with 88.
Include the next digit (7) from the dividend after 88, then repeat: 887 / 90

Advancing to step 4:
90 can be fit into 887 9 times, resulting in a remainder of 77.
Use 9 as the next digit of our solution. 
Result so far: 109.0
If we subtract 810 from 887, we get 77.
Append the next digit (7) from the dividend to 77 and continue with: 777 / 90

Going ahead to step 5:
90 goes into 777 8 times with a remainder of 57.
Record the quotient 8 as the next digit in the result. 
Result so far: 1098.0
Subtract 720 from 777 to get 57.
Take the next digit (5) from the dividend and append it to 57, then repeat: 575 / 90

On to step 6:
90 can be fit into 575 6 times, resulting in a remainder of 35.
The number 6 becomes the next digit in our result. 
Result so far: 10986.0
If we take 540 away from 575, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 7:
90 goes into 350 3 times with a remainder of 80.
Use 3 as the next digit of our solution. 
Result so far: 10986.3
Subtracting 270 from 350 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 8:
800 divided by 90 is 8 with a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 10986.38
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
800 divided by 90 is 8 with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 10986.388
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 10986.388 with a remainder of 0.008.
