We look at the division of 325398 by 30 
The aim is to understand the frequency of 30 in 325398.

On to step 1:
The number 30 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 30

Going ahead to step 2:
32 divided by 30 is 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 30 away from 32, we end up with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 30

Let's proceed to step 3:
The number 30 fits into 25 0 times, leaving a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 25 leaves us with 25.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 30

Step 4:
The number 30 fits into 253 8 times, leaving a remainder of 13.
The next digit of our result is 8. 
Result so far: 108.0
The remainder is 13 after subtracting 240 from 253.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 30

Moving on to step 5:
The number 30 fits into 139 4 times, leaving a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 1084.0
If we subtract 120 from 139, we get 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 30

Step 6:
30 goes into 198 6 times with a remainder of 18.
The next digit of our result is 6. 
Result so far: 10846.0
Deduct 180 from 198 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
30 can be fit into 180 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 10846.6
The remainder is 0 after subtracting 180 from 180.
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:
If we divide 0 by 30, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10846.6
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.

Moving on to step 9:
0 divided by 30 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10846.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 10846.6 with a remaining 0.0.
