We're dividing 318560 by 80 
Let's see how many times 80 fits into 318560.

Advancing to step 1:
3 divided by 80 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 80

Going ahead to step 2:
When dividing 31 by 80, we get 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Take the next digit (8) from the dividend and append it to 31, then repeat: 318 / 80

Advancing to step 3:
When dividing 318 by 80, we get 3 with a remainder of 78.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 78 after subtracting 240 from 318.
Append the next digit (5) from the dividend to 78 and continue with: 785 / 80

Going ahead to step 4:
785 divided by 80 is 9 with a remainder of 65.
The next digit of our result is 9. 
Result so far: 39.0
Subtract 720 from 785 to get 65.
Include the next digit (6) from the dividend after 65, then repeat: 656 / 80

Moving on to step 5:
656 divided by 80 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 398.0
Deduct 640 from 656 and we're left with 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 80

Moving on to step 6:
The number 80 fits into 160 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 3982.0
Subtracting 160 from 160 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.

Let's proceed to step 7:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3982.0
Subtracting 0 from 0 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.

On to step 8:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3982.0
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.

After the division, we end up with 3982.0 and a remainder of 0.0.
