Let's divide 6610 by 30
The aim is to understand the frequency of 30 in 6610.

Advancing to step 1:
30 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 30

Step 2:
30 goes into 66 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 60 from 66 and we're left with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 30

Going ahead to step 3:
The number 30 fits into 61 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 22.0
Subtract 60 from 61 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 30

Let's proceed to step 4:
30 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 220.0
Subtract 0 from 10 to 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.

Step 5:
When dividing 100 by 30, we get 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 220.3
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.

Advancing to step 6:
When dividing 100 by 30, we get 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 220.33
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.

After the division, we end up with 220.33 and a remainder of 0.01.
