We're dividing 186050 by 15 
The aim is to understand the frequency of 15 in 186050.

Let's proceed to step 1:
When dividing 1 by 15, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 15

Step 2:
If we divide 18 by 15, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 15 from 18, we get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 15

Going ahead to step 3:
15 goes into 36 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 30 from 36 leaves us with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 15

Step 4:
15 can be fit into 60 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
If we subtract 60 from 60, we get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 15

Moving on to step 5:
15 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 1240.0
If we subtract 0 from 5, we get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 15

Moving on to step 6:
When dividing 50 by 15, we get 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 12403.0
The remainder is 5 after subtracting 45 from 50.
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 7:
When dividing 50 by 15, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 12403.3
Deduct 45 from 50 and we're left 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.

Let's proceed to step 8:
15 goes into 50 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 12403.33
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.

Our division results in 12403.33 with a remaining 0.005.
