We're dividing 521511 by 80 
We want to divide 521511 by 80.

Moving on to step 1:
80 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 80

Advancing to step 2:
The number 80 fits into 52 0 times, leaving a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Append the next digit (1) from the dividend to 52 and continue with: 521 / 80

Advancing to step 3:
If we divide 521 by 80, we get 6 and a remainder of 41.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 480 from 521 to get 41.
Append the next digit (5) from the dividend to 41 and continue with: 415 / 80

Moving on to step 4:
80 can be fit into 415 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 65.0
Subtract 400 from 415 to get 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 80

Let's proceed to step 5:
The number 80 fits into 151 1 times, leaving a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 651.0
The remainder is 71 after subtracting 80 from 151.
Append the next digit (1) from the dividend to 71 and continue with: 711 / 80

Going ahead to step 6:
80 goes into 711 8 times with a remainder of 71.
The number 8 becomes the next digit in our result. 
Result so far: 6518.0
If we take 640 away from 711, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 7:
80 goes into 710 8 times with a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 6518.8
The remainder is 70 after subtracting 640 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
If we divide 700 by 80, we get 8 and a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 6518.88
If we subtract 640 from 700, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 6518.88 with a balance of 0.06.
