We're dividing 334175 by 15 
The aim is to understand the frequency of 15 in 334175.

Advancing to step 1:
When dividing 3 by 15, we get 0 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 (3) from the dividend, add it to 3, then carry on: 33 / 15

Going ahead to step 2:
15 can be fit into 33 2 times, resulting in a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 30 away from 33, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 15

Let's proceed to step 3:
34 divided by 15 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we take 30 away from 34, we end up with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 15

Step 4:
41 divided by 15 is 2 with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 222.0
Deduct 30 from 41 and we're left with 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 15

Moving on to step 5:
15 can be fit into 117 7 times, resulting in a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 2227.0
If we take 105 away from 117, we end up with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 15

Moving on to step 6:
If we divide 125 by 15, we get 8 and a remainder of 5.
The next digit of our result is 8. 
Result so far: 22278.0
If we take 120 away from 125, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 22278.3
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
15 goes into 50 3 times with a remainder of 5.
The next digit of our result is 3. 
Result so far: 22278.33
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 22278.33, with a leftover of 0.005.
