We look at the division of 315472 by 15 
Our goal is to divide 315472 by 15.

Advancing to step 1:
15 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 15

Step 2:
The number 15 fits into 31 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 30 from 31 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 15

Step 3:
15 divided by 15 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we take 15 away from 15, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 15

Moving on to step 4:
15 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 210.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 15

Moving on to step 5:
15 goes into 47 3 times with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 2103.0
If we subtract 45 from 47, we get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 15

Going ahead to step 6:
The number 15 fits into 22 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 21031.0
Deduct 15 from 22 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
70 divided by 15 is 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 21031.4
Deduct 60 from 70 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.

Let's proceed to step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 21031.46
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
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: 21031.466
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.

The final result is 21031.466 with a remainder of 0.001.
