388504 ÷ 12 
Our goal is to divide 388504 by 12.

Moving on to step 1:
12 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 12

Step 2:
12 can be fit into 38 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 3.0
If we take 36 away from 38, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 12

Advancing to step 3:
The number 12 fits into 28 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 32.0
Deduct 24 from 28 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 12

Going ahead to step 4:
If we divide 45 by 12, we get 3 and a remainder of 9.
The next digit of our result is 3. 
Result so far: 323.0
The remainder is 9 after subtracting 36 from 45.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 12

On to step 5:
If we divide 90 by 12, we get 7 and a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 3237.0
If we subtract 84 from 90, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 12

Moving on to step 6:
64 divided by 12 is 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 32375.0
Subtract 60 from 64 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:
If we divide 40 by 12, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 32375.3
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.

Let's proceed to step 8:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 32375.33
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.

Our division results in 32375.33 with a remaining 0.004.
