We're dividing 261603 by 30 
The aim is to understand the frequency of 30 in 261603.

Going ahead to step 1:
30 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 30

Step 2:
30 can be fit into 26 0 times, resulting in a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Take the next digit (1) from the dividend and append it to 26, then repeat: 261 / 30

Step 3:
30 can be fit into 261 8 times, resulting in a remainder of 21.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 240 from 261 and we're left with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 30

On to step 4:
216 divided by 30 is 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
If we take 210 away from 216, we end up with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 30

Advancing to step 5:
60 divided by 30 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 872.0
Deduct 60 from 60 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 30

Step 6:
When dividing 3 by 30, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 8720.0
The remainder is 3 after subtracting 0 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
The number 30 fits into 30 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 8720.1
Deduct 30 from 30 and we're left 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.

Step 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8720.1
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 9:
When dividing 0 by 30, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8720.1
If we subtract 0 from 0, we 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.

In conclusion, the division gives 8720.1 with a balance of 0.0.
