We look at the division of 33982 by 12 
We want to divide 33982 by 12.

Step 1:
12 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 12

Moving on to step 2:
33 divided by 12 is 2 with a remainder of 9.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 24 from 33, we get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 12

Advancing to step 3:
12 goes into 99 8 times with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we take 96 away from 99, 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 4:
38 divided by 12 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 283.0
Deduct 36 from 38 and we're left with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 12

On to step 5:
If we divide 22 by 12, we get 1 and a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 2831.0
Deduct 12 from 22 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 6:
12 can be fit into 100 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 2831.8
If we subtract 96 from 100, 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 7:
40 divided by 12 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 2831.83
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.

On to step 8:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 2831.833
If we take 36 away from 40, 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.

The final result is 2831.833 with a remainder of 0.0004.
