We look at the division of 172751 by 90 
We want to divide 172751 by 90.

Advancing to step 1:
90 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 90

Moving on to step 2:
When dividing 17 by 90, we get 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 90

Step 3:
The number 90 fits into 172 1 times, leaving a remainder of 82.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 90 from 172 and we're left with 82.
Grab the next digit (7) from the dividend, add it to 82, then carry on: 827 / 90

Moving on to step 4:
90 can be fit into 827 9 times, resulting in a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 810 from 827, we get 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 90

Going ahead to step 5:
175 divided by 90 is 1 with a remainder of 85.
Put 1 as the next digit of the answer. 
Result so far: 191.0
The remainder is 85 after subtracting 90 from 175.
Append the next digit (1) from the dividend to 85 and continue with: 851 / 90

Advancing to step 6:
If we divide 851 by 90, we get 9 and a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 1919.0
If we subtract 810 from 851, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 7:
When dividing 410 by 90, we get 4 with a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 1919.4
If we subtract 360 from 410, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
500 divided by 90 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 1919.45
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
90 can be fit into 500 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 1919.455
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 1919.455 with a balance of 0.005.
