We look at the division of 779707 by 15 
We want to figure out the number of times 779707 can be divided by 15.

Moving on to step 1:
7 divided by 15 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 15

Advancing to step 2:
15 can be fit into 77 5 times, resulting in a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 75 from 77 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 15

Going ahead to step 3:
29 divided by 15 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
The remainder is 14 after subtracting 15 from 29.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 15

Going ahead to step 4:
If we divide 147 by 15, we get 9 and a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 519.0
Deduct 135 from 147 and we're left with 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 15

Step 5:
If we divide 120 by 15, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 5198.0
The remainder is 0 after subtracting 120 from 120.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 15

Step 6:
The number 15 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 51980.0
Subtracting 0 from 7 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
When dividing 70 by 15, we get 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 51980.4
If we subtract 60 from 70, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 15, we get 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 51980.46
If we take 90 away from 100, we end up 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.

Moving on to step 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 51980.466
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 51980.466, with a leftover of 0.001.
