571111 ÷ 30 
The aim is to understand the frequency of 30 in 571111.

Step 1:
30 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 30

Let's proceed to step 2:
If we divide 57 by 30, we get 1 and 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.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 30

On to step 3:
30 goes into 271 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 1 after subtracting 270 from 271.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 30

Step 4:
If we divide 11 by 30, we get 0 and a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 190.0
If we subtract 0 from 11, we get 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 30

Advancing to step 5:
The number 30 fits into 111 3 times, leaving a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 1903.0
Subtracting 90 from 111 leaves us with 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 30

Let's proceed to step 6:
30 can be fit into 211 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 19037.0
Deduct 210 from 211 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
30 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 19037.0
Subtract 0 from 10 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.

Going ahead to step 8:
30 goes into 100 3 times with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 19037.03
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.

Advancing to 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: 19037.033
If we take 90 away from 100, we end up 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 19037.033, and the remainder is 0.001.
