We're dividing 779349 by 15 
Let's see how many times 15 fits into 779349.

Advancing to step 1:
If we divide 7 by 15, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 15

Going ahead to step 2:
15 can be fit into 77 5 times, resulting in a remainder of 2.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 75 from 77 to get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 15

Going ahead to step 3:
The number 15 fits into 29 1 times, leaving a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtracting 15 from 29 leaves us with 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 15

Let's proceed to step 4:
143 divided by 15 is 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 519.0
Subtract 135 from 143 to get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 15

Advancing to step 5:
The number 15 fits into 84 5 times, leaving a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 5195.0
If we take 75 away from 84, we end up with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 15

Let's proceed to step 6:
The number 15 fits into 99 6 times, leaving a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 51956.0
Deduct 90 from 99 and we're left 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.

Let's proceed to step 7:
90 divided by 15 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 51956.6
If we take 90 away from 90, 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.

Let's proceed to step 8:
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: 51956.6
Subtract 0 from 0 to 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.

Moving on to step 9:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 51956.6
Subtract 0 from 0 to 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.

The final result is 51956.6 with a remainder of 0.0.
