Let's divide 3984 by 30
We want to figure out the number of times 3984 can be divided by 30.

Moving on to step 1:
The number 30 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 30

Moving on to step 2:
30 can be fit into 39 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 30 away from 39, we end up with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 30

Moving on to step 3:
98 divided by 30 is 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 90 away from 98, we end up with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 30

Moving on to step 4:
84 divided by 30 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 132.0
Deduct 60 from 84 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 5:
30 can be fit into 240 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 132.8
Subtract 240 from 240 to 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.

Going ahead to step 6:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 132.8
If we take 0 away from 0, we end up 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.

Advancing to step 7:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 132.8
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.

In conclusion, the division gives 132.8 with a balance of 0.0.
