518811 divided by 80 
Let's see how many times 80 fits into 518811.

Moving on to step 1:
When dividing 5 by 80, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 80

Advancing to step 2:
The number 80 fits into 51 0 times, leaving a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Grab the next digit (8) from the dividend, add it to 51, then carry on: 518 / 80

On to step 3:
If we divide 518 by 80, we get 6 and a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 480 from 518, we get 38.
Include the next digit (8) from the dividend after 38, then repeat: 388 / 80

Going ahead to step 4:
80 goes into 388 4 times with a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Deduct 320 from 388 and we're left with 68.
Bring next digit (1) of the dividend behind the 68 and repeat the process: 681 / 80

On to step 5:
If we divide 681 by 80, we get 8 and a remainder of 41.
The number 8 becomes the next digit in our result. 
Result so far: 648.0
The remainder is 41 after subtracting 640 from 681.
Grab the next digit (1) from the dividend, add it to 41, then carry on: 411 / 80

Going ahead to step 6:
When dividing 411 by 80, we get 5 with a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 6485.0
If we take 400 away from 411, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
When dividing 110 by 80, we get 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 6485.1
Subtracting 80 from 110 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
80 can be fit into 300 3 times, resulting in a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 6485.13
If we take 240 away from 300, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
The number 80 fits into 600 7 times, leaving a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 6485.137
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.

On to step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 6485.1375
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 6485.1375
If we take 0 away from 0, we end up 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 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 6485.1375
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.

In conclusion, the division gives 6485.1375 with a balance of 0.0.
