We're dividing 491587 by 80 
We want to divide 491587 by 80.

Step 1:
The number 80 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 80

Step 2:
80 can be fit into 49 0 times, resulting in a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Take the next digit (1) from the dividend and append it to 49, then repeat: 491 / 80

Moving on to step 3:
80 can be fit into 491 6 times, resulting in a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 11 after subtracting 480 from 491.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 80

Step 4:
When dividing 115 by 80, we get 1 with a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 61.0
Subtract 80 from 115 to get 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 80

Step 5:
358 divided by 80 is 4 with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 614.0
The remainder is 38 after subtracting 320 from 358.
Take the next digit (7) from the dividend and append it to 38, then repeat: 387 / 80

Moving on to step 6:
80 can be fit into 387 4 times, resulting in a remainder of 67.
The number 4 becomes the next digit in our result. 
Result so far: 6144.0
Subtract 320 from 387 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 7:
When dividing 670 by 80, we get 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 6144.8
Subtract 640 from 670 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
300 divided by 80 is 3 with a remainder of 60.
The next digit of our result is 3. 
Result so far: 6144.83
Subtract 240 from 300 to 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.

On to step 9:
If we divide 600 by 80, we get 7 and a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 6144.837
Subtract 560 from 600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 6144.8375
Subtract 400 from 400 to 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.

Let's proceed to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 6144.8375
Deduct 0 from 0 and we're left with 0.
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 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6144.8375
The remainder is 0 after subtracting 0 from 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 quotient of the division is 6144.8375, and the remainder is 0.0.
