Zener is a bad way to do that.

I know but it's simple and doesn't 5 other xsistors.

No it ain't simple and worse than just putting resistors in series.
Zener is justified only where a stable voltage needed with unstable source.
Otherwise you dissipate the same power plus the zener dissipation.
It is the worst way. Like using heavy electric motor as a hammer to drive in nails. Will work but do you think it is a goid use of a motor and is it convenient?
