343105 ÷ 30 
The aim is to understand the frequency of 30 in 343105.

Step 1:
30 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 30

On to step 2:
If we divide 34 by 30, we get 1 and a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 30 from 34 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 30

On to step 3:
If we divide 43 by 30, we get 1 and a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 30 from 43 leaves us with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 30

Moving on to step 4:
If we divide 131 by 30, we get 4 and a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 114.0
Subtracting 120 from 131 leaves us with 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 30

Step 5:
The number 30 fits into 110 3 times, leaving a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 1143.0
Subtract 90 from 110 to get 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 30

Step 6:
30 can be fit into 205 6 times, resulting in a remainder of 25.
The next digit of our result is 6. 
Result so far: 11436.0
If we take 180 away from 205, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 7:
If we divide 250 by 30, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 11436.8
Subtract 240 from 250 to 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.

Going ahead 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: 11436.83
Subtracting 90 from 100 leaves us 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.

On to step 9:
When dividing 100 by 30, we get 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 11436.833
Deduct 90 from 100 and we're left 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.

After the division, we end up with 11436.833 and a remainder of 0.001.
