We're dividing 340951 by 30 
The aim is to understand the frequency of 30 in 340951.

Step 1:
30 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 30

Going ahead to step 2:
When dividing 34 by 30, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 30 from 34 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 30

Going ahead to step 3:
30 can be fit into 40 1 times, resulting in a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 30 from 40 to get 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 30

Advancing to step 4:
When dividing 109 by 30, we get 3 with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 113.0
Subtract 90 from 109 to get 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 30

Step 5:
The number 30 fits into 195 6 times, leaving a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 1136.0
If we take 180 away from 195, we end up with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 30

Step 6:
The number 30 fits into 151 5 times, leaving a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 11365.0
Subtract 150 from 151 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
If we divide 10 by 30, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 11365.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 30 is 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 11365.03
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.

Advancing to step 9:
30 can be fit into 100 3 times, resulting in a remainder of 10.
The next digit of our result is 3. 
Result so far: 11365.033
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.

Our division results in 11365.033 with a remaining 0.001.
