We're dividing 532135 by 30 
The aim is to understand the frequency of 30 in 532135.

On to step 1:
30 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 30

Going ahead to step 2:
The number 30 fits into 53 1 times, leaving a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 30 from 53, we get 23.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 30

On to step 3:
232 divided by 30 is 7 with a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 210 from 232 leaves us with 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 30

Moving on to step 4:
When dividing 221 by 30, we get 7 with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 177.0
Deduct 210 from 221 and we're left with 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 30

Moving on to step 5:
30 goes into 113 3 times with a remainder of 23.
The next digit of our result is 3. 
Result so far: 1773.0
If we subtract 90 from 113, we get 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 30

On to step 6:
If we divide 235 by 30, we get 7 and a remainder of 25.
The next digit of our result is 7. 
Result so far: 17737.0
If we take 210 away from 235, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
The number 30 fits into 250 8 times, leaving a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 17737.8
Subtract 240 from 250 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.

On to step 8:
When dividing 100 by 30, we get 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 17737.83
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: 17737.833
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.

After the division, we end up with 17737.833 and a remainder of 0.001.
