Bismillahir Rahmaanir Raheem is repeated in the Holy Quran  114 Times

Every sura in the Quran opens with the statement "In the name of God, Most Gracious, Most Merciful," known as the Bismillah, with the exception of Sura 9 (Surah Tuba).

Surah Naml, which is the 27th Chapter, has the entire bismillahir rahmanir raheem in the 30th verse. This is why Surah Naml is known as the Surah with two bismillahs.
