We're dividing 570311 by 80 
Our goal is to divide 570311 by 80.

Step 1:
When dividing 5 by 80, we get 0 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.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 80

On to step 2:
If we divide 57 by 80, we get 0 and a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Bring next digit (0) of the dividend behind the 57 and repeat the process: 570 / 80

Advancing to step 3:
80 can be fit into 570 7 times, resulting in a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 10 after subtracting 560 from 570.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 80

On to step 4:
The number 80 fits into 103 1 times, leaving a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
Subtract 80 from 103 to get 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 80

Moving on to step 5:
If we divide 231 by 80, we get 2 and a remainder of 71.
Record the quotient 2 as the next digit in the result. 
Result so far: 712.0
If we take 160 away from 231, we end up with 71.
Include the next digit (1) from the dividend after 71, then repeat: 711 / 80

On to step 6:
80 can be fit into 711 8 times, resulting in a remainder of 71.
The number 8 becomes the next digit in our result. 
Result so far: 7128.0
Deduct 640 from 711 and we're left 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.

Step 7:
710 divided by 80 is 8 with a remainder of 70.
The next digit of our result is 8. 
Result so far: 7128.8
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.

Let's proceed to step 8:
If we divide 700 by 80, we get 8 and a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 7128.88
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.

The final result is 7128.88 with a remainder of 0.06.
