Splitting a page into several, how much will it hurt seo?

Question

Search Engine Optimization

We decided to break one article into pages.
Let's say there is a page - Bricks, now figuratively - silicate brick, facing brick, brick for partitions.
And I want to make from 1 page - 4.
1 - a brief description that was at the very beginning of the general page
2,3,4 - these are articles from the first general article (the text will be taken from the general page of bricks)
How will Yasha react to this? What is the same text on another page, but at the same time it is not on the previous one?
Should the text be removed from the general page first and wait, or can it be removed from the general page and immediately transferred to subpages?

Answer 1

It will respond well, just relink and, in addition to the old text, add at least a little more unique one.
