The problem you're referring to is a classic problem in dynamic programming. The problem can be solved by using the concept of Fibonacci series. Here's a step-by-step solution in Python:

1. Define a function, let's call it `count_ways`, that takes an integer `n` as an argument. This integer represents the number of stairs.

```python
def count_ways(n):
```

2. If `n` is 1 or 2, return `n` because there is only one way to reach the first stair (one step) and
