qgis - split regular polygons in regular sub-polygons


In QGIS, I have a layer containing 62 equal-sized, quadratic polygons: enter image description here


I want to split each polygon regularly into 9 quadratic sub-polygons and tried the polygon divider tool. Results are fine for upright polygons, but somewhat rotated input polygons get non-quadratic sub-polygons: enter image description here


Problematic are the irregular alginment and rotation of the input polygons; the sub-polygons should fit the input polygons (e.g. have the same rotation). However, perhaps someone can indicate a solution to this problem?
