We divide 997594 by 90
Our goal is to divide 997594 by 90.

Step 1:
90 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 90

Advancing to step 2:
90 can be fit into 99 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 90 away from 99, we end up with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 90

Let's proceed to step 3:
90 goes into 97 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 90 from 97 leaves us with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 90

Step 4:
75 divided by 90 is 0 with a remainder of 75.
The next digit of our result is 0. 
Result so far: 110.0
Deduct 0 from 75 and we're left with 75.
Grab the next digit (9) from the dividend, add it to 75, then carry on: 759 / 90

On to step 5:
90 goes into 759 8 times with a remainder of 39.
Write down 8 as next digit of the result. 
Result so far: 1108.0
If we subtract 720 from 759, we get 39.
Append the next digit (4) from the dividend to 39 and continue with: 394 / 90

Advancing to step 6:
394 divided by 90 is 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 11084.0
If we subtract 360 from 394, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
If we divide 340 by 90, we get 3 and a remainder of 70.
The number 3 becomes the next digit in our result. 
Result so far: 11084.3
Subtract 270 from 340 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
90 can be fit into 700 7 times, resulting in a remainder of 70.
The next digit of our result is 7. 
Result so far: 11084.37
Subtract 630 from 700 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 9:
90 can be fit into 700 7 times, resulting in a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 11084.377
If we subtract 630 from 700, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 11084.377, with a leftover of 0.007.
