We look at the division of 15831 by 36 
We're looking to find how many times 36 goes into 15831.

Going ahead to step 1:
36 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 36

Going ahead to step 2:
The number 36 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 36

Let's proceed to step 3:
36 goes into 158 4 times with a remainder of 14.
The next digit of our result is 4. 
Result so far: 4.0
If we take 144 away from 158, we end up with 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 36

Let's proceed to step 4:
36 goes into 143 3 times with a remainder of 35.
The next digit of our result is 3. 
Result so far: 43.0
If we subtract 108 from 143, we get 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 36

Let's proceed to step 5:
The number 36 fits into 351 9 times, leaving a remainder of 27.
The next digit of our result is 9. 
Result so far: 439.0
The remainder is 27 after subtracting 324 from 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 6:
When dividing 270 by 36, we get 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 439.7
Subtracting 252 from 270 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
36 can be fit into 180 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 439.75
Subtracting 180 from 180 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
36 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 439.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
36 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 439.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 439.75, and the remainder is 0.0.
