We're dividing 256709 by 30 
The aim is to understand the frequency of 30 in 256709.

Moving on to step 1:
When dividing 2 by 30, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 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.
Fetch the next digit (6) from the dividend, attach it to 25 and continue: 256 / 30

On to step 3:
If we divide 256 by 30, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 16 after subtracting 240 from 256.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 30

Advancing to step 4:
30 goes into 167 5 times with a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 85.0
If we subtract 150 from 167, we get 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 30

Moving on to step 5:
The number 30 fits into 170 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 855.0
If we subtract 150 from 170, we get 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 30

On to step 6:
30 can be fit into 209 6 times, resulting in a remainder of 29.
The number 6 becomes the next digit in our result. 
Result so far: 8556.0
If we take 180 away from 209, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
290 divided by 30 is 9 with a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 8556.9
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.

On to step 8:
The number 30 fits into 200 6 times, leaving a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 8556.96
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
If we divide 200 by 30, we get 6 and a remainder of 20.
The next digit of our result is 6. 
Result so far: 8556.966
Subtracting 180 from 200 leaves us 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.

Our division results in 8556.966 with a remaining 0.002.
