520604 ÷ 80 
We want to divide 520604 by 80.

Advancing to step 1:
The number 80 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 80

Going ahead to step 2:
52 divided by 80 is 0 with a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Take the next digit (0) from the dividend and append it to 52, then repeat: 520 / 80

Let's proceed to step 3:
If we divide 520 by 80, we get 6 and a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 480 from 520, we get 40.
Append the next digit (6) from the dividend to 40 and continue with: 406 / 80

Going ahead to step 4:
80 can be fit into 406 5 times, resulting in a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
The remainder is 6 after subtracting 400 from 406.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 80

Moving on to step 5:
80 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 650.0
Subtract 0 from 60 to get 60.
Grab the next digit (4) from the dividend, add it to 60, then carry on: 604 / 80

Step 6:
If we divide 604 by 80, we get 7 and a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 6507.0
The remainder is 44 after subtracting 560 from 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 7:
When dividing 440 by 80, we get 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 6507.5
Subtracting 400 from 440 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 6507.55
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.

After the division, we end up with 6507.55 and a remainder of 0.0.
