11988 ÷ 30 
We want to figure out the number of times 11988 can be divided by 30.

On to step 1:
When dividing 1 by 30, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 30

Let's proceed to step 2:
The number 30 fits into 11 0 times, leaving a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 30

On to step 3:
If we divide 119 by 30, we get 3 and a remainder of 29.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 90 from 119, we get 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 30

On to step 4:
30 goes into 298 9 times with a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtract 270 from 298 to get 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 30

Step 5:
The number 30 fits into 288 9 times, leaving a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 399.0
Deduct 270 from 288 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 6:
When dividing 180 by 30, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 399.6
If we subtract 180 from 180, 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.

Let's proceed to step 7:
The number 30 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 399.6
Subtract 0 from 0 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.

Advancing to step 8:
0 divided by 30 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 399.6
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 399.6 with a remaining 0.0.
