We look at the division of 380812 by 12 
We want to figure out the number of times 380812 can be divided by 12.

Let's proceed to step 1:
12 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 12

Going ahead to step 2:
12 goes into 38 3 times with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 36 from 38 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 12

Going ahead to step 3:
20 divided by 12 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we subtract 12 from 20, we get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 12

Let's proceed to step 4:
12 goes into 88 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 317.0
Subtract 84 from 88 to get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 12

Let's proceed to step 5:
41 divided by 12 is 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3173.0
If we take 36 away from 41, we end up with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 12

Going ahead to step 6:
12 goes into 52 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 31734.0
If we take 48 away from 52, 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.

Step 7:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 31734.3
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.

Going ahead to step 8:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 31734.33
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.

The quotient of the division is 31734.33, and the remainder is 0.004.
