285982 ÷ 12 
We want to divide 285982 by 12.

Moving on to step 1:
2 divided by 12 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 12

On to step 2:
When dividing 28 by 12, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 24 from 28 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 12

On to step 3:
The number 12 fits into 45 3 times, leaving a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we take 36 away from 45, we end up with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 12

Going ahead to step 4:
99 divided by 12 is 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 238.0
Deduct 96 from 99 and we're left with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 12

Let's proceed to step 5:
12 can be fit into 38 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 2383.0
Subtracting 36 from 38 leaves us with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 12

Let's proceed to step 6:
If we divide 22 by 12, we get 1 and a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 23831.0
Subtract 12 from 22 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
The number 12 fits into 100 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 23831.8
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
When dividing 40 by 12, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 23831.83
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.

Advancing to step 9:
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: 23831.833
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.

Our division results in 23831.833 with a remaining 0.0004.
