Sure, I can help you with that. Here's a step-by-step solution in Python:

1. First, we need to define a list of delivered tracking numbers in ascending order. Let's call it "delivered_numbers".

2. Next, we need to prompt the user to enter the tracking number they want to search for. Let's call this input "search_number".

3. We can use binary search algorithm to efficiently search for the tracking number in the "delivered_numbers" list. Binary search works by repeatedly dividing the search space in half until the target number is found or the search space is empty.

4. To implement binary search, we need to define a function called "binary_search" that takes the "delivered_numbers" list and the "search_number" as parameters.

5. Inside the "binary_search" function, we need to initialize two variables: "low" and "high". "low" will be the index of the first element in the search space, and "high" will be the index of the last element in the search space.

6. We also need to initialize a variable called "comparisons" to keep track of the number of comparisons made during the search process. We start with 0 comparisons.

7. Now, we can start the binary search algorithm. We will use a while loop that continues until the search space is empty (i.e., "low" becomes greater than "high").

8. Inside the while loop, we calculate the middle index of the search space using the formula: middle = (low + high) // 2.

9. We compare the tracking number at the middle index with the "search_number". If they are equal, we return "Delivered" and the number of comparisons made so far.

10. If the tracking number at the middle index is greater than the "search_number", we update the "high" variable to be one less than the middle index.

11. If the tracking number at the middle index is less than the "search_number", we update the "low" variable to be one more than the middle index.

12. We also increment the "comparisons" variable by 1 for each comparison made.

13. If the while loop finishes without finding a match, we return "Not-delivered" and the number of comparisons made.

14. Finally, we call the "binary_search" function with the "delivered_numbers" list and the "search_number" inputted by the user. We print the result and the number of comparisons made.

Here's the Python code for the above steps:

```python
def binary_search(delivered_numbers, search_number):
low = 0
high = len(delivered_numbers) - 1
comparisons = 0

while low

        middle = (low + high) // 2
        comparisons += 1

if delivered_numbers[middle] == search_number:
            return "Delivered", comparisons
        elif delivered_numbers[middle] < search_number:
            low = middle + 1
        else:
            high = middle - 1

return "Not-delivered", comparisons

# Example usage
delivered_numbers = [123, 456, 789, 101112, 131415]
search_number = int(input("Enter the tracking number to search: "))

result, comparisons = binary_search(delivered_numbers, search_number)
print(result)
print("Number of comparisons:", comparisons)
```

Please note that you need to replace the "delivered_numbers" list with your actual list of delivered tracking numbers in ascending order.
