455982 ÷ 15 
We're looking to find how many times 15 goes into 455982.

Moving on to step 1:
If we divide 4 by 15, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 15

Moving on to step 2:
15 goes into 45 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 45 from 45 leaves us with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 15

Let's proceed to step 3:
When dividing 5 by 15, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 30.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 15

Going ahead to step 4:
15 goes into 59 3 times with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 303.0
Deduct 45 from 59 and we're left with 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 15

On to step 5:
When dividing 148 by 15, we get 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 3039.0
The remainder is 13 after subtracting 135 from 148.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 15

Advancing to step 6:
15 can be fit into 132 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 30398.0
Subtract 120 from 132 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
15 goes into 120 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 30398.8
Subtracting 120 from 120 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.

Going ahead to step 8:
When dividing 0 by 15, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 30398.8
If we take 0 away from 0, we end up 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.

Step 9:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 30398.8
Deduct 0 from 0 and we're left 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 final outcome is 30398.8, with a leftover of 0.0.
