Let's divide 520933 by 30
The aim is to understand the frequency of 30 in 520933.

Advancing to step 1:
The number 30 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 30

Going ahead to step 2:
30 can be fit into 52 1 times, resulting in a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 30 from 52, we get 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 30

Going ahead to step 3:
The number 30 fits into 220 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 17.0
If we subtract 210 from 220, we get 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 30

Moving on to step 4:
30 goes into 109 3 times with a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 173.0
If we subtract 90 from 109, we get 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 30

Moving on to step 5:
30 can be fit into 193 6 times, resulting in a remainder of 13.
The next digit of our result is 6. 
Result so far: 1736.0
The remainder is 13 after subtracting 180 from 193.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 30

Moving on to step 6:
30 can be fit into 133 4 times, resulting in a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 17364.0
Subtracting 120 from 133 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
If we divide 130 by 30, we get 4 and a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 17364.4
The remainder is 10 after subtracting 120 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
When dividing 100 by 30, we get 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 17364.43
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.

On to step 9:
When dividing 100 by 30, we get 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 17364.433
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.

The quotient of the division is 17364.433, and the remainder is 0.001.
