121360 ÷ 30 
The aim is to understand the frequency of 30 in 121360.

Advancing to step 1:
30 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 30

Step 2:
The number 30 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 30

Step 3:
121 divided by 30 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 120 away from 121, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 30

On to step 4:
30 can be fit into 13 0 times, resulting in a remainder of 13.
The next digit of our result is 0. 
Result so far: 40.0
If we take 0 away from 13, we end up with 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 30

On to step 5:
If we divide 136 by 30, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 404.0
If we subtract 120 from 136, we get 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 30

Going ahead to step 6:
The number 30 fits into 160 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 4045.0
Subtracting 150 from 160 leaves us 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.

Moving on to step 7:
If we divide 100 by 30, we get 3 and a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 4045.3
If we subtract 90 from 100, we 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.

Going ahead to step 8:
30 goes into 100 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 4045.33
Subtracting 90 from 100 leaves us 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.

The final result is 4045.33 with a remainder of 0.01.
