We divide 717198 by 30
The aim is to understand the frequency of 30 in 717198.

Advancing to step 1:
7 divided by 30 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 30

Moving on to step 2:
If we divide 71 by 30, we get 2 and a remainder of 11.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 60 from 71 and we're left with 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 30

Step 3:
117 divided by 30 is 3 with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we subtract 90 from 117, we get 27.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 30

Step 4:
If we divide 271 by 30, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 239.0
Subtract 270 from 271 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 30

Let's proceed to step 5:
The number 30 fits into 19 0 times, leaving a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 2390.0
Subtracting 0 from 19 leaves us with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 30

Going ahead to step 6:
30 goes into 198 6 times with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 23906.0
Subtract 180 from 198 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
The number 30 fits into 180 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 23906.6
Subtract 180 from 180 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
When dividing 0 by 30, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 23906.6
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 23906.6
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 23906.6 with a remainder of 0.0.
