Here is a Python solution for the problem:

```python
def reverse_id(n):
reversed_id = 0
while n 0:
digit = n % 10
if digit == 0 and reversed_id == 0:
n //= 10
continue
reversed_id = reversed_id * 10 + digit
n //= 10
return reversed_id

# Test cases
print(reverse_id(18760)) # Output: 6781
print(reverse_id(23075)) # Output: 5732
print(reverse_id(10000)) # Output: 1
print(reverse_id(99999)) # Output: 99999
```

This Python function `reverse_id` takes an integer `n` as input and processes it as follows:

1. It initializes `reversed_id` to 0. This variable will hold the reversed ID.
2. It enters a while loop that continues as long as `n` is greater than 0.
3. Inside the loop, it calculates the last digit of `n` by taking `n` modulo 10.
4. If this digit is 0 and `reversed_id` is still 0, it means we are dealing with a leading zero in the original ID. In this case, it simply discards the zero by dividing `n` by 10 (using integer division) and continues to the next iteration of the loop.
5. If the digit is not a leading zero, it adds it to `reversed_id`, effectively appending it to the end of the reversed ID.
6. It then removes the last digit from `n` by dividing it by 10 (using integer division).
7. Once the loop is finished (i.e., all digits of `n` have been processed), it returns `reversed_id`.

The test cases at the end of the script demonstrate the function's usage and confirm that it works as expected.
