We look at the division of 312448 by 15 
Our goal is to divide 312448 by 15.

Let's proceed to step 1:
When dividing 3 by 15, we get 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.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 15

Moving on to step 2:
The number 15 fits into 31 2 times, leaving a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 1 after subtracting 30 from 31.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 15

Going ahead to step 3:
When dividing 12 by 15, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 15

On to step 4:
15 can be fit into 124 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 208.0
Subtract 120 from 124 to get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 15

Advancing to step 5:
If we divide 44 by 15, we get 2 and a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 2082.0
If we subtract 30 from 44, we get 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 15

Moving on to step 6:
15 goes into 148 9 times with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 20829.0
If we subtract 135 from 148, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
130 divided by 15 is 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 20829.8
Deduct 120 from 130 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
If we divide 100 by 15, we get 6 and a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 20829.86
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
When dividing 100 by 15, we get 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 20829.866
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 20829.866 and a remainder of 0.001.
