We divide 553999 by 30
The aim is to understand the frequency of 30 in 553999.

Moving 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
The remainder is 5 after subtracting 0 from 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 30

Going ahead to step 2:
55 divided by 30 is 1 with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 30 away from 55, we end up with 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 30

Let's proceed to step 3:
30 can be fit into 253 8 times, resulting in a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 240 from 253, we get 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 30

Step 4:
30 goes into 139 4 times with a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 184.0
If we subtract 120 from 139, we get 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 30

On to step 5:
199 divided by 30 is 6 with a remainder of 19.
The next digit of our result is 6. 
Result so far: 1846.0
Subtract 180 from 199 to get 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 30

On to step 6:
When dividing 199 by 30, we get 6 with a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 18466.0
If we take 180 away from 199, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
If we divide 190 by 30, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 18466.6
If we subtract 180 from 190, 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.

Advancing to step 8:
When dividing 100 by 30, we get 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 18466.63
If we take 90 away from 100, 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 9:
When dividing 100 by 30, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 18466.633
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.

In conclusion, the division gives 18466.633 with a balance of 0.001.
