Let's divide 779172 by 15
Let's see how many times 15 fits into 779172.

Advancing to step 1:
7 divided by 15 is 0 with 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 (7) from the dividend to 7 and continue with: 77 / 15

Going ahead to step 2:
When dividing 77 by 15, we get 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 2 after subtracting 75 from 77.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 15

Going ahead to step 3:
15 goes into 29 1 times with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 51.0
Subtracting 15 from 29 leaves us with 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 15

On to step 4:
If we divide 141 by 15, we get 9 and a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 519.0
Subtract 135 from 141 to get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 15

Advancing to step 5:
The number 15 fits into 67 4 times, leaving a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 5194.0
Deduct 60 from 67 and we're left with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 15

Going ahead to step 6:
15 can be fit into 72 4 times, resulting in a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 51944.0
The remainder is 12 after subtracting 60 from 72.
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 can be fit into 120 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 51944.8
If we subtract 120 from 120, 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.

Step 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 51944.8
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.

Let's proceed to step 9:
15 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 51944.8
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.

In conclusion, the division gives 51944.8 with a balance of 0.0.
