We look at the division of 284864 by 12 
Let's see how many times 12 fits into 284864.

Advancing to step 1:
When dividing 2 by 12, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 12

Let's proceed to step 2:
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: 2.0
If we take 24 away from 28, we end up with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 12

Let's proceed to step 3:
The number 12 fits into 44 3 times, leaving a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we subtract 36 from 44, we get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 12

Advancing to step 4:
88 divided by 12 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 237.0
If we subtract 84 from 88, we get 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 12

On to step 5:
The number 12 fits into 46 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 2373.0
If we take 36 away from 46, we end up with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 12

Going ahead to step 6:
The number 12 fits into 104 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 23738.0
If we take 96 away from 104, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 23738.6
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
When dividing 80 by 12, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 23738.66
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 23738.66 with a remainder of 0.008.
