We're dividing 312651 by 15 
We're looking to find how many times 15 goes into 312651.

Moving on to step 1:
The number 15 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 15

Step 2:
15 can be fit into 31 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 30 from 31 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 15

Let's proceed to step 3:
When dividing 12 by 15, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 15

Moving on to step 4:
When dividing 126 by 15, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 208.0
Deduct 120 from 126 and we're left with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 15

Advancing to step 5:
65 divided by 15 is 4 with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 2084.0
Subtract 60 from 65 to get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 15

On to step 6:
15 goes into 51 3 times with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 20843.0
Deduct 45 from 51 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
When dividing 60 by 15, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 20843.4
If we subtract 60 from 60, 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.

Let's proceed to step 8:
When dividing 0 by 15, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 20843.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
15 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: 20843.4
Subtracting 0 from 0 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.

The quotient of the division is 20843.4, and the remainder is 0.0.
