The Rebbe describes the following as a core teaching of the Baal Shem Tov:
Not only are the pirouettes of a leaf as it falls off a tree,
the quivering of a blade of grass in the wind,
and all the details of the world around you
all brought into being, given life and directed every moment from Above—
but beyond that:
Every nuance is an essential component of a grand and G‑dly scheme, the gestalt of all those vital minutiae.
Every moment burns with the pulse of G‑d’s desire.
Meditate on this. And then think:
How much more so the details of my daily life.

Where does free will fit in?
Yes, our free will and every choice we make is also part of that grand scheme. Even the wrong choice eventually leads the right way.
We have several important articles on the concept of free choice. Among them:
Free Will in Judaism
Why It's Okay That Free Will Is Paradoxical
Amen, Rabbi Freeman. Additionally, sometimes the decisions we are forced to make is b/c of the choices others made. But our merciful and gracious GD perfects our steps. When we look back, we find ourselves in a better place. Trust GD He knows what He is doing for us. Thank you.
