We look at the division of 431515 by 36 
We want to divide 431515 by 36.

On to step 1:
The number 36 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 36

Advancing to step 2:
The number 36 fits into 43 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 36 from 43 and we're left with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 36

On to step 3:
71 divided by 36 is 1 with a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 36 from 71 to get 35.
Include the next digit (5) from the dividend after 35, then repeat: 355 / 36

On to step 4:
355 divided by 36 is 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 119.0
Subtracting 324 from 355 leaves us with 31.
Append the next digit (1) from the dividend to 31 and continue with: 311 / 36

Advancing to step 5:
If we divide 311 by 36, we get 8 and a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 1198.0
Deduct 288 from 311 and we're left with 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 36

Going ahead to step 6:
When dividing 235 by 36, we get 6 with a remainder of 19.
The next digit of our result is 6. 
Result so far: 11986.0
The remainder is 19 after subtracting 216 from 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
190 divided by 36 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 11986.5
The remainder is 10 after subtracting 180 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 36, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 11986.52
If we take 72 away from 100, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
When dividing 280 by 36, we get 7 with a remainder of 28.
The next digit of our result is 7. 
Result so far: 11986.527
Subtract 252 from 280 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
36 goes into 280 7 times with a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 11986.5277
If we take 252 away from 280, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 11986.5277 and a remainder of 0.00028.
