778815 ÷ 10 
We're looking to find how many times 10 goes into 778815.

Step 1:
When dividing 7 by 10, we get 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.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 10

Advancing to step 2:
If we divide 77 by 10, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 70 from 77, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 10

Going ahead to step 3:
10 goes into 78 7 times with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Subtract 70 from 78 to get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 10

Going ahead to step 4:
10 goes into 88 8 times with a remainder of 8.
The next digit of our result is 8. 
Result so far: 778.0
The remainder is 8 after subtracting 80 from 88.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 10

On to step 5:
If we divide 81 by 10, we get 8 and a remainder of 1.
The next digit of our result is 8. 
Result so far: 7788.0
The remainder is 1 after subtracting 80 from 81.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 10

On to step 6:
The number 10 fits into 15 1 times, leaving a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 77881.0
Subtract 10 from 15 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
When dividing 50 by 10, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 77881.5
Deduct 50 from 50 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.

Advancing to step 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 77881.5
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.

Advancing to step 9:
When dividing 0 by 10, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 77881.5
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.

In conclusion, the division gives 77881.5 with a balance of 0.0.
