We're dividing 613600 by 30 
The aim is to understand the frequency of 30 in 613600.

Moving on to step 1:
The number 30 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 30

Let's proceed to step 2:
If we divide 61 by 30, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 60 from 61 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 30

Step 3:
The number 30 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we take 0 away from 13, we end up with 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 30

Advancing to step 4:
30 can be fit into 136 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 204.0
Subtracting 120 from 136 leaves us with 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 30

On to step 5:
If we divide 160 by 30, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 2045.0
The remainder is 10 after subtracting 150 from 160.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 30

Moving on to step 6:
100 divided by 30 is 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 20453.0
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.

On to step 7:
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: 20453.3
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.

Going ahead to step 8:
If we divide 100 by 30, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 20453.33
Deduct 90 from 100 and we're left 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.

Our division results in 20453.33 with a remaining 0.01.
