We look at the division of 830688 by 80 
Let's see how many times 80 fits into 830688.

Step 1:
If we divide 8 by 80, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 80

On to step 2:
80 can be fit into 83 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 80 from 83, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 80

Advancing to step 3:
30 divided by 80 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 30 to get 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 80

Moving on to step 4:
The number 80 fits into 306 3 times, leaving a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
If we take 240 away from 306, we end up with 66.
Bring next digit (8) of the dividend behind the 66 and repeat the process: 668 / 80

Advancing to step 5:
80 can be fit into 668 8 times, resulting in a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 1038.0
The remainder is 28 after subtracting 640 from 668.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 80

Step 6:
If we divide 288 by 80, we get 3 and a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 10383.0
The remainder is 48 after subtracting 240 from 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
When dividing 480 by 80, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 10383.6
Subtracting 480 from 480 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.

Moving on to step 8:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10383.6
If we subtract 0 from 0, 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 9:
0 divided by 80 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10383.6
If we subtract 0 from 0, 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.

In conclusion, the division gives 10383.6 with a balance of 0.0.
