Here is a step-by-step solution in Python:

1. First, we need to accept two integers as input. Let's call the first integer `num` and the second integer `k`.

```python
num = int(input("Enter the number: "))
k = int(input("Enter the number of digits to reverse: "))
```

2. Next, we need to extract the last `k` digits from `num`. We can do this by converting `num` to a string, slicing the last `k` characters, and then converting back to an integer.

```python
last_k_digits = int(str(num)[-k:])
```

3. Now, we need to reverse these `k` digits. We can do this by converting `last_k_digits` to a string, reversing the string using slicing, and then converting back to an integer.

```python
reversed_digits = int(str(last_k_digits)[::-1])
```

4. Finally, we need to replace the last `k` digits of `num` with `reversed_digits`. We can do this by subtracting `last_k_digits` from `num`, and then adding `reversed_digits`.

```python
num = num - last_k_digits
num = num + reversed_digits
```

5. Print the final result.

```python
print("The number after reversing the last k digits is: ", num)
```

Please note that this solution assumes that `num` has at least `k` digits. If `num` has fewer than `k` digits, the program will reverse all the digits of `num`.
