As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.

There are 14 Sajdah Tilawat in The Quran which are indicated by the word ‘As Sajdah’ shown in the margin and also on the specific verse. The 14 verses are as follows,

1) Surah Al A’Raf (7) Ayat 206
2) Surah Al Ra’d (13) Ayat 15
3) Surah Al Nahl (16) Ayat 50
4) Surah Bani Israeel (17) Ayat 109
5) Surah Maryam (19) Ayat 58
6) Surah Al Haj (22) Ayat 18
7) Surah Al Furqan (25) Ayat 60
8) Surah Al Naml (27) Ayat 26
9) Surah As Sajdah (32) Ayat 15
10) Surah Saad (38) Ayat 24
11) Surah Hameem Sajdah (41) Ayat 38
12) Surah Al Najam (53) Ayat 62
13) Surah Inshiqaq (84) Ayat 21
14) Surah Al Alaq (96) Ayat 19
When one recites or hears any of these verses, it is necessary (wajib) to perform sajdah tilawat. One should try to perform the sajdah as soon as possible. In the case that one forgot, it would remain necessary (wajib) to perform it.[1]
The procedure of Sajidah Tilawat is in the state of Wudhu stand up and say: 'Allahu Akbar' without raising the hands; then go straight down into Sajdah; read 'Subhaana Rabbiyal A'ala' three times; arise out of Sajdah and 'whilst standing up say; 'Allahu Akbar'. There is no Tasleem (Salaam) after standing up. Although it is better to begin and end this Sajdah from a standing position, it is also correct to commence and terminate it from the Jalsa (sitting) position[2].
Sajdatut Tilawat is prohibited whilst the sun is rising, precisely at noon, and from the time the color of the sun changes before sunset until the sun has fully set.
You should average the amount of Quran you read without doing Sajdah Tilawah and accordingly perform the Sajdahs.
