533506 divided by 30 
The aim is to understand the frequency of 30 in 533506.

Let's proceed to step 1:
If we divide 5 by 30, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 30

Moving on to step 2:
30 can be fit into 53 1 times, resulting in a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 30 from 53, we get 23.
Include the next digit (3) from the dividend after 23, then repeat: 233 / 30

On to step 3:
30 goes into 233 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtract 210 from 233 to get 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 30

Step 4:
30 goes into 235 7 times with a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 177.0
Deduct 210 from 235 and we're left with 25.
Take the next digit (0) from the dividend and append it to 25, then repeat: 250 / 30

On to step 5:
30 can be fit into 250 8 times, resulting in a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 1778.0
Deduct 240 from 250 and we're left with 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 30

Step 6:
30 goes into 106 3 times with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 17783.0
If we take 90 away from 106, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
When dividing 160 by 30, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 17783.5
Deduct 150 from 160 and we're left 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 8:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 17783.53
Subtract 90 from 100 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.

Advancing to step 9:
30 goes into 100 3 times with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 17783.533
Deduct 90 from 100 and we're left 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.

After the division, we end up with 17783.533 and a remainder of 0.001.
