508831 ÷ 30 
The aim is to understand the frequency of 30 in 508831.

Advancing to step 1:
If we divide 5 by 30, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 30

Let's proceed to step 2:
When dividing 50 by 30, we get 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 30 from 50 to get 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 30

Moving on to step 3:
30 can be fit into 208 6 times, resulting in a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 180 from 208 and we're left with 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 30

Moving on to step 4:
When dividing 288 by 30, we get 9 with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 169.0
If we take 270 away from 288, we end up with 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 30

Moving on to step 5:
183 divided by 30 is 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 1696.0
If we subtract 180 from 183, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 30

Moving on to step 6:
If we divide 31 by 30, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 16961.0
If we take 30 away from 31, we end up 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.

Advancing to step 7:
30 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 16961.0
If we take 0 away from 10, 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.

Going ahead to step 8:
100 divided by 30 is 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 16961.03
If we subtract 90 from 100, we 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 9:
100 divided by 30 is 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 16961.033
If we subtract 90 from 100, we 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.

Our division results in 16961.033 with a remaining 0.001.
