We're dividing 287668 by 12 
We're looking to find how many times 12 goes into 287668.

Let's proceed to step 1:
12 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 12

Let's proceed to step 2:
28 divided by 12 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 24 away from 28, we end up with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 12

Step 3:
47 divided by 12 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 23.0
The remainder is 11 after subtracting 36 from 47.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 12

Let's proceed to step 4:
12 can be fit into 116 9 times, resulting in a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 239.0
The remainder is 8 after subtracting 108 from 116.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 12

Step 5:
When dividing 86 by 12, we get 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 2397.0
The remainder is 2 after subtracting 84 from 86.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 12

Moving on to step 6:
12 can be fit into 28 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 23972.0
Subtracting 24 from 28 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.

Moving on to step 7:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 23972.3
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:
When dividing 40 by 12, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 23972.33
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.

The quotient of the division is 23972.33, and the remainder is 0.004.
