Let's divide 599597 by 30
The aim is to understand the frequency of 30 in 599597.

Going ahead to step 1:
30 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 30

Moving on to step 2:
When dividing 59 by 30, we get 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 30 away from 59, we end up with 29.
Take the next digit (9) from the dividend and append it to 29, then repeat: 299 / 30

On to step 3:
299 divided by 30 is 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 270 from 299 to get 29.
Grab the next digit (5) from the dividend, add it to 29, then carry on: 295 / 30

Advancing to step 4:
30 goes into 295 9 times with a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 199.0
The remainder is 25 after subtracting 270 from 295.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 30

On to step 5:
When dividing 259 by 30, we get 8 with a remainder of 19.
The next digit of our result is 8. 
Result so far: 1998.0
If we take 240 away from 259, we end up with 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 30

Step 6:
30 can be fit into 197 6 times, resulting in a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 19986.0
If we subtract 180 from 197, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
The number 30 fits into 170 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 19986.5
The remainder is 20 after subtracting 150 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
If we divide 200 by 30, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 19986.56
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
If we divide 200 by 30, we get 6 and a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 19986.566
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.

After the division, we end up with 19986.566 and a remainder of 0.002.
