We're dividing 657571 by 80 
Our goal is to divide 657571 by 80.

Let's proceed to step 1:
6 divided by 80 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 80

Let's proceed to step 2:
If we divide 65 by 80, we get 0 and a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Bring next digit (7) of the dividend behind the 65 and repeat the process: 657 / 80

Let's proceed to step 3:
If we divide 657 by 80, we get 8 and a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 640 from 657, we get 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 80

Step 4:
The number 80 fits into 175 2 times, leaving a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
Deduct 160 from 175 and we're left with 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 80

Going ahead to step 5:
80 goes into 157 1 times with a remainder of 77.
The number 1 becomes the next digit in our result. 
Result so far: 821.0
Subtracting 80 from 157 leaves us with 77.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 80

Advancing to step 6:
If we divide 771 by 80, we get 9 and a remainder of 51.
The next digit of our result is 9. 
Result so far: 8219.0
If we subtract 720 from 771, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 7:
The number 80 fits into 510 6 times, leaving a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 8219.6
Subtracting 480 from 510 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.

Going ahead to step 8:
When dividing 300 by 80, we get 3 with a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 8219.63
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.

Let's proceed to step 9:
If we divide 600 by 80, we get 7 and a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 8219.637
Deduct 560 from 600 and we're left 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.

Step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 8219.6375
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.

Advancing to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 8219.6375
If we subtract 0 from 0, 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.

Step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8219.6375
If we subtract 0 from 0, 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.

The final result is 8219.6375 with a remainder of 0.0.
