780519 divided by 15 
We want to divide 780519 by 15.

Moving on to step 1:
If we divide 7 by 15, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 15

Advancing to step 2:
The number 15 fits into 78 5 times, leaving a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 75 away from 78, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 15

Moving on to step 3:
If we divide 30 by 15, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 52.0
Subtracting 30 from 30 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 15

Moving on to step 4:
When dividing 5 by 15, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 520.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 15

Going ahead to step 5:
When dividing 51 by 15, we get 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 5203.0
Deduct 45 from 51 and we're left with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 15

On to step 6:
15 goes into 69 4 times with a remainder of 9.
The next digit of our result is 4. 
Result so far: 52034.0
Subtract 60 from 69 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
When dividing 90 by 15, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 52034.6
If we subtract 90 from 90, we get 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:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 52034.6
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.

Going ahead to step 9:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 52034.6
The remainder is 0 after subtracting 0 from 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 result is 52034.6 with a remainder of 0.0.
