396136 ÷ 12 
Let's see how many times 12 fits into 396136.

Going ahead 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
If we subtract 0 from 3, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 12

Going ahead to step 2:
39 divided by 12 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 36 from 39 to get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 12

Step 3:
If we divide 36 by 12, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Deduct 36 from 36 and we're left with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 12

Going ahead to step 4:
If we divide 1 by 12, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 330.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 12

Moving on to step 5:
The number 12 fits into 13 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 3301.0
Deduct 12 from 13 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 12

Advancing to step 6:
The number 12 fits into 16 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 33011.0
If we take 12 away from 16, 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.

On to step 7:
If we divide 40 by 12, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 33011.3
If we subtract 36 from 40, 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.

On to step 8:
12 goes into 40 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 33011.33
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.

The quotient of the division is 33011.33, and the remainder is 0.004.
