We look at the division of 875290 by 90 
We want to figure out the number of times 875290 can be divided by 90.

On to step 1:
8 divided by 90 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 90

Step 2:
If we divide 87 by 90, we get 0 and a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Take the next digit (5) from the dividend and append it to 87, then repeat: 875 / 90

Advancing to step 3:
90 goes into 875 9 times with a remainder of 65.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 810 from 875 leaves us with 65.
Grab the next digit (2) from the dividend, add it to 65, then carry on: 652 / 90

Going ahead to step 4:
90 goes into 652 7 times with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
Deduct 630 from 652 and we're left with 22.
Take the next digit (9) from the dividend and append it to 22, then repeat: 229 / 90

On to step 5:
If we divide 229 by 90, we get 2 and a remainder of 49.
Write down 2 as next digit of the result. 
Result so far: 972.0
The remainder is 49 after subtracting 180 from 229.
Bring next digit (0) of the dividend behind the 49 and repeat the process: 490 / 90

Step 6:
490 divided by 90 is 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 9725.0
If we take 450 away from 490, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
90 can be fit into 400 4 times, resulting in a remainder of 40.
The next digit of our result is 4. 
Result so far: 9725.4
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
The number 90 fits into 400 4 times, leaving a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 9725.44
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 9725.44 with a balance of 0.04.
