2650 divided by 15 
The aim is to understand the frequency of 15 in 2650.

Let's proceed to step 1:
15 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 15

Step 2:
When dividing 26 by 15, we get 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 11 after subtracting 15 from 26.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 15

Going ahead to step 3:
15 can be fit into 115 7 times, resulting in a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 105 away from 115, we end up with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 15

Moving on to step 4:
15 goes into 100 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 176.0
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.

On to step 5:
15 goes into 100 6 times with a remainder of 10.
The next digit of our result is 6. 
Result so far: 176.6
If we subtract 90 from 100, 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.

On to step 6:
The number 15 fits into 100 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 176.66
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.

After the division, we end up with 176.66 and a remainder of 0.01.
