343885 divided by 30 
The aim is to understand the frequency of 30 in 343885.

Advancing to step 1:
If we divide 3 by 30, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 30

Advancing to step 2:
The number 30 fits into 34 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 4 after subtracting 30 from 34.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 30

Let's proceed to step 3:
When dividing 43 by 30, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 30 from 43, we get 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 30

Step 4:
When dividing 138 by 30, we get 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
Deduct 120 from 138 and we're left with 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 30

Let's proceed to step 5:
The number 30 fits into 188 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 1146.0
Deduct 180 from 188 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 30

On to step 6:
When dividing 85 by 30, we get 2 with a remainder of 25.
The next digit of our result is 2. 
Result so far: 11462.0
If we take 60 away from 85, 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.

Advancing to step 7:
The number 30 fits into 250 8 times, leaving a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 11462.8
If we subtract 240 from 250, 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.

Going ahead to step 8:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 11462.83
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.

Let's proceed to step 9:
The number 30 fits into 100 3 times, leaving a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 11462.833
If we take 90 away from 100, we end up 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.

In conclusion, the division gives 11462.833 with a balance of 0.001.
