Uwagi
Metoda Divide wykonuje dzielenie całkowite; wszystkie pozostałe wyniki z dzielenia są odrzucane. Aby wykonać dzielenie liczb całkowitych przy zachowaniu reszty, wywołaj metodę DivRem . Aby pobrać tylko resztę, wywołaj metodę Remainder .
Metoda Divide może być używana przez języki, które nie obsługują przeciążenia operatora. Jego zachowanie jest identyczne z dzieleniem przy użyciu operatora dzielenia.
