Possible interpretations and corrections:
* "How many times does it rain in... ?" This is the most likely interpretation, but we need to know the place or time period. For example:
* "How many times does it rain in a year?" (pleut combien de fois par an?)
* "How many times does it rain in Paris?" (pleut combien de fois à Paris?)
* "It rains how many times in... ?" This could be a sentence fragment, like:
* "It rains how many times in a year, I wonder?" (Il pleut combien de fois par an, je me demande?)
