How does he get sin(theta)/theta / 1+ sintheta/theta *1/costheta

I don't understand how he goes from sinetheta/theta + tantheta to sin(theta)/theta / 1+ sintheta/theta *1/costheta

to me it looks like he just brought up the theta like theta/1 and just bumped up the theta but i know you cant do that.

3. The attempt at a solution

Ive tried too many times, there is my question if anyone can help. I appreciate it.
