We look at the division of 562207 by 30 
The aim is to understand the frequency of 30 in 562207.

Advancing to step 1:
If we divide 5 by 30, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 30

On to step 2:
When dividing 56 by 30, we get 1 with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 26 after subtracting 30 from 56.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 30

On to step 3:
When dividing 262 by 30, we get 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtract 240 from 262 to get 22.
Bring next digit (2) of the dividend behind the 22 and repeat the process: 222 / 30

Step 4:
The number 30 fits into 222 7 times, leaving a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 187.0
Subtract 210 from 222 to get 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 30

Moving on to step 5:
120 divided by 30 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 1874.0
Deduct 120 from 120 and we're left with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 30

Step 6:
30 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 18740.0
Subtract 0 from 7 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
When dividing 70 by 30, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 18740.2
If we subtract 60 from 70, we 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.

On to step 8:
If we divide 100 by 30, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 18740.23
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.

Step 9:
The number 30 fits into 100 3 times, leaving a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 18740.233
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.

The final outcome is 18740.233, with a leftover of 0.001.
