How can a single surah be divided between two rak'ahs in prayer, and is it permissible to divide it from any point within the surah?

It is permissible to divide a Surah over two Rak'ahs in prayer, with a preference for lengthening the recitation in the first Rak'ah and shortening it in the second. It is better to recite a complete Surah in each Rak'ah, even if it is short, and when dividing a Surah, the meaning must be taken into consideration.
