We're dividing 171095 by 15 
The aim is to understand the frequency of 15 in 171095.

Going ahead to step 1:
1 divided by 15 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 15

On to step 2:
When dividing 17 by 15, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 15 from 17 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 15

Step 3:
When dividing 21 by 15, we get 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 15 from 21 leaves us with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 15

Moving on to step 4:
When dividing 60 by 15, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
Subtract 60 from 60 to get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 15

Let's proceed to step 5:
When dividing 9 by 15, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 1140.0
Subtract 0 from 9 to get 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 15

Going ahead to step 6:
95 divided by 15 is 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 11406.0
If we subtract 90 from 95, we 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.

Let's proceed to step 7:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 11406.3
If we subtract 45 from 50, we 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:
If we divide 50 by 15, we get 3 and a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 11406.33
If we take 45 away from 50, 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.

In conclusion, the division gives 11406.33 with a balance of 0.005.
