78828457 divided by 815 
We want to divide 78828457 by 815.

On to step 1:
815 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 815

Moving on to step 2:
815 can be fit into 78 0 times, resulting in a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Take the next digit (8) from the dividend and append it to 78, then repeat: 788 / 815

Let's proceed to step 3:
If we divide 788 by 815, we get 0 and a remainder of 788.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 788, we get 788.
Bring next digit (2) of the dividend behind the 788 and repeat the process: 7882 / 815

Advancing to step 4:
7882 divided by 815 is 9 with a remainder of 547.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 7335 from 7882 leaves us with 547.
Append the next digit (8) from the dividend to 547 and continue with: 5478 / 815

Step 5:
If we divide 5478 by 815, we get 6 and a remainder of 588.
Use 6 as the next digit of our solution. 
Result so far: 96.0
Subtracting 4890 from 5478 leaves us with 588.
Bring next digit (4) of the dividend behind the 588 and repeat the process: 5884 / 815

Step 6:
815 goes into 5884 7 times with a remainder of 179.
Put 7 as the next digit of the answer. 
Result so far: 967.0
The remainder is 179 after subtracting 5705 from 5884.
Fetch the next digit (5) from the dividend, attach it to 179 and continue: 1795 / 815

Going ahead to step 7:
When dividing 1795 by 815, we get 2 with a remainder of 165.
Write down 2 as next digit of the result. 
Result so far: 9672.0
If we subtract 1630 from 1795, we get 165.
Fetch the next digit (7) from the dividend, attach it to 165 and continue: 1657 / 815

Going ahead to step 8:
The number 815 fits into 1657 2 times, leaving a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 96722.0
The remainder is 27 after subtracting 1630 from 1657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 9:
815 goes into 270 0 times with a remainder of 270.
The next digit of our result is 0. 
Result so far: 96722.0
Subtract 0 from 270 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 10:
2700 divided by 815 is 3 with a remainder of 255.
Put 3 as the next digit of the answer. 
Result so far: 96722.03
The remainder is 255 after subtracting 2445 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 11:
When dividing 2550 by 815, we get 3 with a remainder of 105.
The number 3 becomes the next digit in our result. 
Result so far: 96722.033
The remainder is 105 after subtracting 2445 from 2550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

In conclusion, the division gives 96722.033 with a balance of 0.0105.
