Have you considered using any of the add-ons that are designed with memorizing lengthy text specifically in mind?

LPCG, AnkiPoetry, Cloze Overlapper, Verse cloze, etc.

See for links –

Memorise Poems effectively

There is an add-on to create cloze cards automatically from the longer text: LPCG (Lyrics/Poetry Cloze Generator) You may want to play a little with the settings, but it should generate the right material for you.
