We look at the division of 259409 by 30 
The aim is to understand the frequency of 30 in 259409.

On to step 1:
30 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 30

Advancing to step 2:
30 can be fit into 25 0 times, resulting in a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 30

Let's proceed to step 3:
If we divide 259 by 30, we get 8 and a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 240 from 259 to get 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 30

Going ahead to step 4:
194 divided by 30 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Deduct 180 from 194 and we're left with 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 30

Let's proceed to step 5:
30 goes into 140 4 times with a remainder of 20.
The next digit of our result is 4. 
Result so far: 864.0
Subtracting 120 from 140 leaves us with 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 30

Advancing to step 6:
If we divide 209 by 30, we get 6 and a remainder of 29.
Record the quotient 6 as the next digit in the result. 
Result so far: 8646.0
The remainder is 29 after subtracting 180 from 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
30 goes into 290 9 times with a remainder of 20.
The next digit of our result is 9. 
Result so far: 8646.9
Subtract 270 from 290 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 8646.96
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
When dividing 200 by 30, we get 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 8646.966
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 8646.966 with a balance of 0.002.
