313840 divided by 12 
We want to divide 313840 by 12.

Moving on to step 1:
3 divided by 12 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 12

Going ahead to step 2:
If we divide 31 by 12, we get 2 and a remainder of 7.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 24 from 31, we get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 12

On to step 3:
12 goes into 73 6 times with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
The remainder is 1 after subtracting 72 from 73.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 12

Moving on to step 4:
If we divide 18 by 12, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 261.0
If we subtract 12 from 18, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 12

Moving on to step 5:
The number 12 fits into 64 5 times, leaving a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 2615.0
Subtract 60 from 64 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 12

Advancing to step 6:
40 divided by 12 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 26153.0
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
12 can be fit into 40 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 26153.3
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
12 goes into 40 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 26153.33
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 26153.33 with a balance of 0.004.
