We look at the division of 591632 by 30 
The aim is to understand the frequency of 30 in 591632.

Advancing to step 1:
5 divided by 30 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 30

Step 2:
The number 30 fits into 59 1 times, leaving a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 30 from 59 and we're left with 29.
Take the next digit (1) from the dividend and append it to 29, then repeat: 291 / 30

Moving on to step 3:
The number 30 fits into 291 9 times, leaving a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 270 from 291 and we're left with 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 30

Let's proceed to step 4:
30 can be fit into 216 7 times, resulting in a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 197.0
If we subtract 210 from 216, we get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 30

Step 5:
30 can be fit into 63 2 times, resulting in a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 1972.0
If we subtract 60 from 63, we get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 30

Step 6:
32 divided by 30 is 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 19721.0
If we subtract 30 from 32, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
30 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 19721.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
200 divided by 30 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 19721.06
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
200 divided by 30 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 19721.066
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 19721.066, and the remainder is 0.002.
