316486 ÷ 15 
Let's see how many times 15 fits into 316486.

Moving on to step 1:
15 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 15

Advancing to step 2:
15 goes into 31 2 times with 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.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 15

Let's proceed to step 3:
16 divided by 15 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we take 15 away from 16, we end up with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 15

Step 4:
If we divide 14 by 15, we get 0 and a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 210.0
If we subtract 0 from 14, we get 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 15

Let's proceed to step 5:
148 divided by 15 is 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 2109.0
If we subtract 135 from 148, we get 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 15

Let's proceed to step 6:
When dividing 136 by 15, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 21099.0
Subtract 135 from 136 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
15 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 21099.0
Subtract 0 from 10 to 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 8:
100 divided by 15 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 21099.06
Subtract 90 from 100 to 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.

Let's proceed to step 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 21099.066
Deduct 90 from 100 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.

The final outcome is 21099.066, with a leftover of 0.001.
