We divide 343459 by 30
The aim is to understand the frequency of 30 in 343459.

Going ahead to step 1:
When dividing 3 by 30, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 30

Step 2:
34 divided by 30 is 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
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

Moving on to step 3:
When dividing 43 by 30, we get 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 30 from 43 and we're left with 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 30

Advancing to step 4:
30 goes into 134 4 times with a remainder of 14.
The next digit of our result is 4. 
Result so far: 114.0
If we take 120 away from 134, we end up with 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 30

Let's proceed to step 5:
The number 30 fits into 145 4 times, leaving a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 1144.0
The remainder is 25 after subtracting 120 from 145.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 30

Step 6:
If we divide 259 by 30, we get 8 and a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 11448.0
If we subtract 240 from 259, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
30 goes into 190 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 11448.6
Deduct 180 from 190 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.

Step 8:
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: 11448.63
If we subtract 90 from 100, we 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.

Moving on to step 9:
100 divided by 30 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 11448.633
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.

After the division, we end up with 11448.633 and a remainder of 0.001.
