We look at the division of 115352 by 90 
We want to figure out the number of times 115352 can be divided by 90.

Let's proceed to step 1:
The number 90 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 90

Going ahead to step 2:
The number 90 fits into 11 0 times, leaving a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 90

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
The remainder is 25 after subtracting 90 from 115.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 90

On to step 4:
90 goes into 253 2 times with a remainder of 73.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 180 from 253 and we're left with 73.
Include the next digit (5) from the dividend after 73, then repeat: 735 / 90

Going ahead to step 5:
90 can be fit into 735 8 times, resulting in a remainder of 15.
The next digit of our result is 8. 
Result so far: 128.0
The remainder is 15 after subtracting 720 from 735.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 90

Going ahead to step 6:
When dividing 152 by 90, we get 1 with a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 1281.0
If we take 90 away from 152, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 7:
If we divide 620 by 90, we get 6 and a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 1281.6
Subtracting 540 from 620 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 8:
The number 90 fits into 800 8 times, leaving a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 1281.68
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
90 can be fit into 800 8 times, resulting in a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 1281.688
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 1281.688 with a remaining 0.008.
