We divide 480817 by 15
We're looking to find how many times 15 goes into 480817.

Step 1:
When dividing 4 by 15, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 15

Advancing to step 2:
15 can be fit into 48 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 45 from 48 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 15

Moving on to step 3:
If we divide 30 by 15, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 32.0
The remainder is 0 after subtracting 30 from 30.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 15

Moving on to step 4:
8 divided by 15 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 320.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 15

On to step 5:
When dividing 81 by 15, we get 5 with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 3205.0
The remainder is 6 after subtracting 75 from 81.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 15

Going ahead to step 6:
15 goes into 67 4 times with a remainder of 7.
The next digit of our result is 4. 
Result so far: 32054.0
If we subtract 60 from 67, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
15 goes into 70 4 times with a remainder of 10.
The next digit of our result is 4. 
Result so far: 32054.4
Subtracting 60 from 70 leaves us 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:
When dividing 100 by 15, we get 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 32054.46
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.

Advancing to step 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 32054.466
Subtracting 90 from 100 leaves us 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 32054.466, with a leftover of 0.001.
