We divide 80319 by 15
We want to divide 80319 by 15.

Going ahead to step 1:
8 divided by 15 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 15

Step 2:
15 can be fit into 80 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 75 from 80, we get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 15

On to step 3:
15 goes into 53 3 times with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
Subtracting 45 from 53 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 15

Step 4:
15 goes into 81 5 times with a remainder of 6.
The next digit of our result is 5. 
Result so far: 535.0
The remainder is 6 after subtracting 75 from 81.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 15

On to step 5:
15 can be fit into 69 4 times, resulting in a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 5354.0
If we take 60 away from 69, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 6:
When dividing 90 by 15, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 5354.6
Subtracting 90 from 90 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.

Step 7:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5354.6
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.

Let's proceed to step 8:
If we divide 0 by 15, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5354.6
Subtracting 0 from 0 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.

The final outcome is 5354.6, with a leftover of 0.0.
