We divide 720430 by 30
The aim is to understand the frequency of 30 in 720430.

Let's proceed to step 1:
30 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 30

Going ahead to step 2:
The number 30 fits into 72 2 times, leaving a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 60 from 72, we get 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 30

Let's proceed to step 3:
When dividing 120 by 30, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtracting 120 from 120 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 30

Going ahead to step 4:
The number 30 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 240.0
If we take 0 away from 4, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 30

Going ahead to step 5:
When dividing 43 by 30, we get 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 2401.0
If we subtract 30 from 43, we get 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 30

Let's proceed to step 6:
When dividing 130 by 30, we get 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 24014.0
If we take 120 away from 130, we end up 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.

Let's proceed to step 7:
30 can be fit into 100 3 times, resulting in a remainder of 10.
The next digit of our result is 3. 
Result so far: 24014.3
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.

Step 8:
100 divided by 30 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 24014.33
Subtract 90 from 100 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.

The final result is 24014.33 with a remainder of 0.01.
