We're dividing 115250 by 90 
Let's see how many times 90 fits into 115250.

Going ahead to step 1:
90 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 90

Going ahead to step 2:
When dividing 11 by 90, we get 0 with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 90

Moving on to step 3:
90 goes into 115 1 times with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 90 from 115 leaves us with 25.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 90

Moving on to step 4:
252 divided by 90 is 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 180 from 252 and we're left with 72.
Bring next digit (5) of the dividend behind the 72 and repeat the process: 725 / 90

Let's proceed to step 5:
When dividing 725 by 90, we get 8 with a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
Deduct 720 from 725 and we're left with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 90

Advancing to step 6:
If we divide 50 by 90, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 1280.0
Subtract 0 from 50 to 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.

Moving on to step 7:
If we divide 500 by 90, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 1280.5
If we take 450 away from 500, we end up 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.

Going ahead 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: 1280.55
Deduct 450 from 500 and we're left 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.

The final outcome is 1280.55, with a leftover of 0.05.
