We divide 602658 by 30
The aim is to understand the frequency of 30 in 602658.

Advancing to step 1:
30 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 30

On to step 2:
The number 30 fits into 60 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 60 from 60 and we're left with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 30

Advancing to step 3:
If we divide 2 by 30, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 30

Step 4:
26 divided by 30 is 0 with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 200.0
Deduct 0 from 26 and we're left with 26.
Take the next digit (5) from the dividend and append it to 26, then repeat: 265 / 30

Let's proceed to step 5:
If we divide 265 by 30, we get 8 and a remainder of 25.
The next digit of our result is 8. 
Result so far: 2008.0
Subtracting 240 from 265 leaves us with 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 30

Step 6:
When dividing 258 by 30, we get 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 20088.0
The remainder is 18 after subtracting 240 from 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
When dividing 180 by 30, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 20088.6
Subtract 180 from 180 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
0 divided by 30 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20088.6
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20088.6
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 20088.6 with a balance of 0.0.
