We're dividing 571690 by 30 
The aim is to understand the frequency of 30 in 571690.

Advancing to step 1:
When dividing 5 by 30, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 30

On to step 2:
When dividing 57 by 30, we get 1 with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 30 from 57 and we're left with 27.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 30

Advancing to step 3:
30 can be fit into 271 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 19.0
The remainder is 1 after subtracting 270 from 271.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 30

On to step 4:
If we divide 16 by 30, we get 0 and a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 190.0
Subtracting 0 from 16 leaves us with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 30

Let's proceed to step 5:
30 can be fit into 169 5 times, resulting in a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 1905.0
Subtracting 150 from 169 leaves us with 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 30

On to step 6:
When dividing 190 by 30, we get 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 19056.0
Subtract 180 from 190 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.

Moving on to step 7:
100 divided by 30 is 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 19056.3
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.

Moving on to step 8:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 19056.33
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 19056.33 with a balance of 0.01.
