We look at the division of 90542 by 36 
We're looking to find how many times 36 goes into 90542.

On to step 1:
The number 36 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 36

On to step 2:
If we divide 90 by 36, we get 2 and a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 72 from 90, we get 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 36

On to step 3:
When dividing 185 by 36, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtract 180 from 185 to get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 36

Going ahead to step 4:
36 goes into 54 1 times with a remainder of 18.
The next digit of our result is 1. 
Result so far: 251.0
Deduct 36 from 54 and we're left with 18.
Bring next digit (2) of the dividend behind the 18 and repeat the process: 182 / 36

Advancing to step 5:
36 can be fit into 182 5 times, resulting in a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 2515.0
Subtract 180 from 182 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 6:
36 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2515.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
36 can be fit into 200 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 2515.05
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
36 goes into 200 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 2515.055
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 2515.055 with a remainder of 0.002.
