572541 ÷ 30 
The aim is to understand the frequency of 30 in 572541.

Advancing to step 1:
5 divided by 30 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 30

On to step 2:
57 divided by 30 is 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 30 from 57, we get 27.
Include the next digit (2) from the dividend after 27, then repeat: 272 / 30

On to step 3:
272 divided by 30 is 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 19.0
The remainder is 2 after subtracting 270 from 272.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 30

Advancing to step 4:
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: 190.0
Subtract 0 from 25 to get 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 30

Advancing to step 5:
254 divided by 30 is 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 1908.0
If we take 240 away from 254, we end up with 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 30

Let's proceed to step 6:
141 divided by 30 is 4 with a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 19084.0
Subtracting 120 from 141 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
30 goes into 210 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 19084.7
If we subtract 210 from 210, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
0 divided by 30 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19084.7
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.

Going ahead to step 9:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 19084.7
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.

After the division, we end up with 19084.7 and a remainder of 0.0.
