318904 divided by 80 
Our goal is to divide 318904 by 80.

Advancing to step 1:
80 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 80

Going ahead to step 2:
If we divide 31 by 80, we get 0 and a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 80

Advancing to step 3:
The number 80 fits into 318 3 times, leaving a remainder of 78.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 240 away from 318, we end up with 78.
Grab the next digit (9) from the dividend, add it to 78, then carry on: 789 / 80

Going ahead to step 4:
80 goes into 789 9 times with a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtracting 720 from 789 leaves us with 69.
Include the next digit (0) from the dividend after 69, then repeat: 690 / 80

Going ahead to step 5:
690 divided by 80 is 8 with a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 398.0
The remainder is 50 after subtracting 640 from 690.
Include the next digit (4) from the dividend after 50, then repeat: 504 / 80

Step 6:
504 divided by 80 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 3986.0
If we subtract 480 from 504, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
When dividing 240 by 80, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3986.3
The remainder is 0 after subtracting 240 from 240.
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 8:
80 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3986.3
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.

On to step 9:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3986.3
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.

The quotient of the division is 3986.3, and the remainder is 0.0.
