We look at the division of 570933 by 30 
The aim is to understand the frequency of 30 in 570933.

Advancing to step 1:
30 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 30

Moving on to step 2:
The number 30 fits into 57 1 times, leaving a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 30 away from 57, we end up with 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 30

Advancing to step 3:
30 can be fit into 270 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 270 from 270 to get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 30

Advancing to step 4:
If we divide 9 by 30, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 190.0
Subtract 0 from 9 to get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 30

Advancing to step 5:
If we divide 93 by 30, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 1903.0
Subtracting 90 from 93 leaves us with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 30

Let's proceed to step 6:
The number 30 fits into 33 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 19031.0
If we subtract 30 from 33, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
The number 30 fits into 30 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 19031.1
Deduct 30 from 30 and we're left with 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:
If we divide 0 by 30, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 19031.1
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
0 divided by 30 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 19031.1
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.

In conclusion, the division gives 19031.1 with a balance of 0.0.
