We look at the division of 313054 by 80 
We want to divide 313054 by 80.

Step 1:
The number 80 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 80

On to step 2:
If we divide 31 by 80, we get 0 and a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 80

Going ahead to step 3:
If we divide 313 by 80, we get 3 and a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 73 after subtracting 240 from 313.
Take the next digit (0) from the dividend and append it to 73, then repeat: 730 / 80

Let's proceed to step 4:
If we divide 730 by 80, we get 9 and a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 39.0
The remainder is 10 after subtracting 720 from 730.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 80

Let's proceed to step 5:
80 can be fit into 105 1 times, resulting in a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 391.0
Subtracting 80 from 105 leaves us with 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 80

Let's proceed to step 6:
80 can be fit into 254 3 times, resulting in a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 3913.0
Subtracting 240 from 254 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
When dividing 140 by 80, we get 1 with a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 3913.1
Deduct 80 from 140 and we're left with 60.
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 8:
80 can be fit into 600 7 times, resulting in a remainder of 40.
The next digit of our result is 7. 
Result so far: 3913.17
If we subtract 560 from 600, we 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.

Moving on to step 9:
If we divide 400 by 80, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 3913.175
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.

Advancing to step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3913.175
If we subtract 0 from 0, we 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.

Moving on to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3913.175
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.

The final result is 3913.175 with a remainder of 0.0.
