We look at the division of 307396 by 12 
Our goal is to divide 307396 by 12.

Moving on to step 1:
The number 12 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 12

Moving on to step 2:
When dividing 30 by 12, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 6 after subtracting 24 from 30.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 12

Moving on to step 3:
67 divided by 12 is 5 with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 60 from 67 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 12

Going ahead to step 4:
12 can be fit into 73 6 times, resulting in a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 256.0
The remainder is 1 after subtracting 72 from 73.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 12

Going ahead to step 5:
When dividing 19 by 12, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 2561.0
Subtracting 12 from 19 leaves us with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 12

Let's proceed to step 6:
12 can be fit into 76 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 25616.0
Subtract 72 from 76 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.

Moving on to step 7:
40 divided by 12 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 25616.3
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.

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: 25616.33
If we take 36 away from 40, we end up 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.

The final result is 25616.33 with a remainder of 0.004.
