680915 divided by 80 
We want to figure out the number of times 680915 can be divided by 80.

Advancing to step 1:
6 divided by 80 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 80

Advancing to step 2:
The number 80 fits into 68 0 times, leaving a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Include the next digit (0) from the dividend after 68, then repeat: 680 / 80

On to step 3:
680 divided by 80 is 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 640 from 680 and we're left with 40.
Fetch the next digit (9) from the dividend, attach it to 40 and continue: 409 / 80

Step 4:
If we divide 409 by 80, we get 5 and a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
If we take 400 away from 409, we end up with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 80

Let's proceed to step 5:
If we divide 91 by 80, we get 1 and a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 851.0
The remainder is 11 after subtracting 80 from 91.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 80

Step 6:
80 goes into 115 1 times with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 8511.0
Subtract 80 from 115 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 7:
80 goes into 350 4 times with a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 8511.4
If we subtract 320 from 350, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
300 divided by 80 is 3 with a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 8511.43
The remainder is 60 after subtracting 240 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
When dividing 600 by 80, we get 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 8511.437
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 8511.4375
If we subtract 400 from 400, 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.

Moving on to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8511.4375
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.

Let's proceed to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8511.4375
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.

In conclusion, the division gives 8511.4375 with a balance of 0.0.
