We're dividing 487591 by 80 
We're looking to find how many times 80 goes into 487591.

Going ahead to step 1:
The number 80 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 80

Step 2:
48 divided by 80 is 0 with a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Append the next digit (7) from the dividend to 48 and continue with: 487 / 80

Let's proceed to step 3:
80 goes into 487 6 times with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 480 from 487 and we're left with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 80

Moving on to step 4:
If we divide 75 by 80, we get 0 and a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
Subtracting 0 from 75 leaves us with 75.
Fetch the next digit (9) from the dividend, attach it to 75 and continue: 759 / 80

Advancing to step 5:
The number 80 fits into 759 9 times, leaving a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 609.0
If we subtract 720 from 759, we get 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 80

Step 6:
When dividing 391 by 80, we get 4 with a remainder of 71.
Use 4 as the next digit of our solution. 
Result so far: 6094.0
Deduct 320 from 391 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.

Let's proceed to step 7:
80 can be fit into 710 8 times, resulting in a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 6094.8
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.

Step 8:
When dividing 700 by 80, we get 8 with a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 6094.88
Subtracting 640 from 700 leaves us 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.

The quotient of the division is 6094.88, and the remainder is 0.06.
