We're dividing 110981 by 30 
The aim is to understand the frequency of 30 in 110981.

Going ahead to step 1:
1 divided by 30 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 30

On to step 2:
If we divide 11 by 30, we get 0 and a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 30

Moving on to step 3:
The number 30 fits into 110 3 times, leaving a remainder of 20.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 90 from 110, we get 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 30

Step 4:
209 divided by 30 is 6 with a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we subtract 180 from 209, we get 29.
Take the next digit (8) from the dividend and append it to 29, then repeat: 298 / 30

On to step 5:
The number 30 fits into 298 9 times, leaving a remainder of 28.
The next digit of our result is 9. 
Result so far: 369.0
The remainder is 28 after subtracting 270 from 298.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 30

Let's proceed to step 6:
281 divided by 30 is 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 3699.0
Subtracting 270 from 281 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
The number 30 fits into 110 3 times, leaving a remainder of 20.
The next digit of our result is 3. 
Result so far: 3699.3
Subtract 90 from 110 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 3699.36
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
When dividing 200 by 30, we get 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 3699.366
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 3699.366 and a remainder of 0.002.
