We look at the division of 775278 by 15 
We're looking to find how many times 15 goes into 775278.

Moving on to step 1:
15 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in 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

On to step 2:
If we divide 77 by 15, we get 5 and a remainder of 2.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 75 from 77 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 15

On to step 3:
If we divide 25 by 15, we get 1 and a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Subtract 15 from 25 to get 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 15

Let's proceed to step 4:
15 can be fit into 102 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 516.0
If we subtract 90 from 102, we get 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 15

Step 5:
127 divided by 15 is 8 with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 5168.0
If we subtract 120 from 127, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 15

Moving on to step 6:
The number 15 fits into 78 5 times, leaving a remainder of 3.
The next digit of our result is 5. 
Result so far: 51685.0
If we take 75 away from 78, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
15 goes into 30 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 51685.2
The remainder is 0 after subtracting 30 from 30.
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 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 51685.2
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.

Let's proceed to step 9:
0 divided by 15 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 51685.2
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 51685.2 with a remainder of 0.0.
