We divide 317186 by 80
We want to figure out the number of times 317186 can be divided by 80.

On to step 1:
When dividing 3 by 80, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 80

Step 2:
80 goes into 31 0 times with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Take the next digit (7) from the dividend and append it to 31, then repeat: 317 / 80

Advancing to step 3:
80 goes into 317 3 times with a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 240 from 317 to get 77.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 80

Step 4:
80 goes into 771 9 times with a remainder of 51.
The next digit of our result is 9. 
Result so far: 39.0
Subtracting 720 from 771 leaves us with 51.
Grab the next digit (8) from the dividend, add it to 51, then carry on: 518 / 80

Moving on to step 5:
When dividing 518 by 80, we get 6 with a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 396.0
Subtract 480 from 518 to get 38.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 80

Step 6:
386 divided by 80 is 4 with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 3964.0
If we take 320 away from 386, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 7:
If we divide 660 by 80, we get 8 and a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 3964.8
Deduct 640 from 660 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
When dividing 200 by 80, we get 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 3964.82
Deduct 160 from 200 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.

Moving on to step 9:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 3964.825
If we take 400 away from 400, 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.

On to step 10:
0 divided by 80 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3964.825
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.

On to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3964.825
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.

In conclusion, the division gives 3964.825 with a balance of 0.0.
