We're dividing 318497 by 15 
We want to divide 318497 by 15.

Step 1:
When dividing 3 by 15, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 15

Moving on to step 2:
The number 15 fits into 31 2 times, leaving a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 1 after subtracting 30 from 31.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 15

Advancing to step 3:
18 divided by 15 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtracting 15 from 18 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 15

Advancing to step 4:
When dividing 34 by 15, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 212.0
Subtracting 30 from 34 leaves us with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 15

Moving on to step 5:
49 divided by 15 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 2123.0
The remainder is 4 after subtracting 45 from 49.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 15

On to step 6:
15 can be fit into 47 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 21233.0
Deduct 45 from 47 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
When dividing 20 by 15, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 21233.1
Subtract 15 from 20 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
If we divide 50 by 15, we get 3 and a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 21233.13
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 21233.133
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 21233.133 with a remainder of 0.0005.
