We divide 988174 by 90
We want to figure out the number of times 988174 can be divided by 90.

Moving on to step 1:
9 divided by 90 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
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

Let's proceed to step 2:
90 goes into 98 1 times with a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 90 from 98 leaves us with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 90

Moving on to step 3:
90 can be fit into 88 0 times, resulting in a remainder of 88.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 88 to get 88.
Fetch the next digit (1) from the dividend, attach it to 88 and continue: 881 / 90

Going ahead to step 4:
90 goes into 881 9 times with a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 109.0
Subtracting 810 from 881 leaves us with 71.
Fetch the next digit (7) from the dividend, attach it to 71 and continue: 717 / 90

Let's proceed to step 5:
When dividing 717 by 90, we get 7 with a remainder of 87.
Use 7 as the next digit of our solution. 
Result so far: 1097.0
If we take 630 away from 717, we end up with 87.
Grab the next digit (4) from the dividend, add it to 87, then carry on: 874 / 90

Let's proceed to step 6:
874 divided by 90 is 9 with a remainder of 64.
Record the quotient 9 as the next digit in the result. 
Result so far: 10979.0
If we subtract 810 from 874, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 7:
The number 90 fits into 640 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 10979.7
The remainder is 10 after subtracting 630 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
90 goes into 100 1 times with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 10979.71
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
100 divided by 90 is 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 10979.711
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 10979.711 and a remainder of 0.001.
