317391 divided by 80 
We're looking to find how many times 80 goes into 317391.

Moving on to step 1:
The number 80 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 80

On to step 2:
80 goes into 31 0 times with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (7) from the dividend, add it to 31, then carry on: 317 / 80

Going ahead to step 3:
When dividing 317 by 80, we get 3 with a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 240 from 317 leaves us with 77.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 80

Step 4:
773 divided by 80 is 9 with a remainder of 53.
The next digit of our result is 9. 
Result so far: 39.0
The remainder is 53 after subtracting 720 from 773.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 80

On to step 5:
80 goes into 539 6 times with a remainder of 59.
Put 6 as the next digit of the answer. 
Result so far: 396.0
If we subtract 480 from 539, we get 59.
Grab the next digit (1) from the dividend, add it to 59, then carry on: 591 / 80

Let's proceed to step 6:
80 can be fit into 591 7 times, resulting in a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 3967.0
If we take 560 away from 591, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
80 can be fit into 310 3 times, resulting in a remainder of 70.
Use 3 as the next digit of our solution. 
Result so far: 3967.3
If we take 240 away from 310, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
The number 80 fits into 700 8 times, leaving a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 3967.38
The remainder is 60 after subtracting 640 from 700.
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:
When dividing 600 by 80, we get 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 3967.387
Subtracting 560 from 600 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.

On to step 10:
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: 3967.3875
Subtracting 400 from 400 leaves us 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.

Step 11:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3967.3875
If we take 0 away from 0, we end up 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.

Step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3967.3875
If we take 0 away from 0, we end up 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.

Our division results in 3967.3875 with a remaining 0.0.
