We look at the division of 563128 by 30 
The aim is to understand the frequency of 30 in 563128.

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

Let's proceed to step 2:
56 divided by 30 is 1 with a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 30 from 56 to get 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 30

On to step 3:
If we divide 263 by 30, we get 8 and a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 240 from 263, we get 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 30

Let's proceed to step 4:
30 goes into 231 7 times with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 187.0
Subtract 210 from 231 to get 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 30

Going ahead to step 5:
30 can be fit into 212 7 times, resulting in a remainder of 2.
The next digit of our result is 7. 
Result so far: 1877.0
Subtract 210 from 212 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 30

On to step 6:
When dividing 28 by 30, we get 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 18770.0
Subtracting 0 from 28 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 7:
280 divided by 30 is 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 18770.9
Subtracting 270 from 280 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.

Let's proceed to step 8:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 18770.93
Deduct 90 from 100 and we're left 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.

Step 9:
If we divide 100 by 30, we get 3 and a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 18770.933
Deduct 90 from 100 and we're left 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 quotient of the division is 18770.933, and the remainder is 0.001.
