Let's divide 311386 by 12
We're looking to find how many times 12 goes into 311386.

Advancing to step 1:
If we divide 3 by 12, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 12

Advancing to step 2:
12 can be fit into 31 2 times, resulting in a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 7 after subtracting 24 from 31.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 12

On to step 3:
If we divide 71 by 12, we get 5 and a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtract 60 from 71 to get 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 12

Let's proceed to step 4:
12 can be fit into 113 9 times, resulting in a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 259.0
If we subtract 108 from 113, we get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 12

Step 5:
The number 12 fits into 58 4 times, leaving a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 2594.0
Deduct 48 from 58 and we're left with 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 12

Going ahead to step 6:
The number 12 fits into 106 8 times, leaving a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 25948.0
If we subtract 96 from 106, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
If we divide 100 by 12, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 25948.8
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
When dividing 40 by 12, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 25948.83
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.

On to step 9:
40 divided by 12 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 25948.833
Subtract 36 from 40 to get 4.
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 25948.833 with a balance of 0.0004.
