We're dividing 285312 by 12 
Let's see how many times 12 fits into 285312.

Let's proceed to step 1:
If we divide 2 by 12, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 12

On to step 2:
When dividing 28 by 12, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 24 from 28 to get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 12

Step 3:
45 divided by 12 is 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 36 from 45 leaves us with 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 12

On to step 4:
93 divided by 12 is 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 237.0
Subtracting 84 from 93 leaves us with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 12

Let's proceed to step 5:
12 can be fit into 91 7 times, resulting in a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 2377.0
Deduct 84 from 91 and we're left with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 12

Moving on to step 6:
If we divide 72 by 12, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 23776.0
The remainder is 0 after subtracting 72 from 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
When dividing 0 by 12, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 23776.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
When dividing 0 by 12, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 23776.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 23776.0 with a remaining 0.0.
