We look at the division of 261122 by 30 
The aim is to understand the frequency of 30 in 261122.

Let's proceed to step 1:
If we divide 2 by 30, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 30

Let's proceed to step 2:
30 goes into 26 0 times with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 26 to get 26.
Append the next digit (1) from the dividend to 26 and continue with: 261 / 30

Advancing to step 3:
261 divided by 30 is 8 with a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 240 from 261, we get 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 30

Let's proceed to step 4:
30 goes into 211 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 87.0
The remainder is 1 after subtracting 210 from 211.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 30

Advancing to step 5:
30 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 870.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 30

On to step 6:
If we divide 122 by 30, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 8704.0
If we take 120 away from 122, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
If we divide 20 by 30, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 8704.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 8704.06
If we take 180 away from 200, we end up 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.

Step 9:
30 goes into 200 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 8704.066
Subtract 180 from 200 to 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.

In conclusion, the division gives 8704.066 with a balance of 0.002.
