We look at the division of 396130 by 12 
Let's see how many times 12 fits into 396130.

Let's proceed to step 1:
The number 12 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 12

Going ahead to step 2:
The number 12 fits into 39 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 36 from 39 to get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 12

Let's proceed to step 3:
12 can be fit into 36 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Deduct 36 from 36 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 12

Step 4:
12 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 330.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 12

On to step 5:
12 goes into 13 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 3301.0
The remainder is 1 after subtracting 12 from 13.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 12

Step 6:
12 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 33010.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
12 goes into 100 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 33010.8
The remainder is 4 after subtracting 96 from 100.
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 8:
40 divided by 12 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 33010.83
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.

Moving on to step 9:
When dividing 40 by 12, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 33010.833
Subtracting 36 from 40 leaves us 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.

Our division results in 33010.833 with a remaining 0.0004.
