311235 divided by 15 
We're looking to find how many times 15 goes into 311235.

Advancing to step 1:
3 divided by 15 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 15

Step 2:
The number 15 fits into 31 2 times, leaving a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 30 away from 31, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 15

Let's proceed to step 3:
11 divided by 15 is 0 with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 11 and we're left with 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 15

Going ahead to step 4:
When dividing 112 by 15, we get 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 207.0
Subtract 105 from 112 to get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 15

On to step 5:
When dividing 73 by 15, we get 4 with a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 2074.0
The remainder is 13 after subtracting 60 from 73.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 15

Let's proceed to step 6:
15 goes into 135 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 20749.0
The remainder is 0 after subtracting 135 from 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
15 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20749.0
If we take 0 away from 0, we end up 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.

Let's proceed to step 8:
If we divide 0 by 15, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20749.0
If we subtract 0 from 0, we 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 20749.0, and the remainder is 0.0.
