311393 divided by 12 
Let's see how many times 12 fits into 311393.

Advancing to step 1:
3 divided by 12 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 12

Let's proceed to step 2:
12 goes into 31 2 times with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 24 from 31 and we're left with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 12

Going ahead to step 3:
If we divide 71 by 12, we get 5 and a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 60 from 71 and we're left with 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 12

Advancing to step 4:
113 divided by 12 is 9 with 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 (9) from the dividend and append it to 5, then repeat: 59 / 12

Step 5:
59 divided by 12 is 4 with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 2594.0
Deduct 48 from 59 and we're left with 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 12

Step 6:
The number 12 fits into 113 9 times, leaving a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 25949.0
Subtracting 108 from 113 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
12 goes into 50 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 25949.4
If we subtract 48 from 50, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
If we divide 20 by 12, we get 1 and a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 25949.41
Subtract 12 from 20 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 25949.416
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
When dividing 80 by 12, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 25949.4166
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 25949.4166, with a leftover of 8e-05.
