If someone recites an aayah of sujud repeatedly for memorization, how many times does he/she make the sujud

Assalaamualaikum. I am trying to memorize the Qur'an in sha Allaah. Some surah's have aayah of sujood. So, if I repeatedly recite that soorah many times for memorization, how many times do I have to make the sujood? As many times as I recited, or is just one enough. Please give references to your answers. JazaakAllaahu khair
