problem_description: Statement
  
  Takahashi likes the sound when he buys a drink from a vending machine.
  
  That sound can be heard by spending A yen (the currency of Japan) each time.
  
  Takahashi has B yen. He will hear the sound as many times as he can with that
  money, but at most C times, as he would be satisfied at that time.
  
  How many times will he hear the sound?
