Division of polygon into irregular shape and varying area of polygons [closed]

Question

I have a major polygon showing in the following image and its area is 264387.097089999995660 hectare (area can be in any unit, mostly in hectare),

I want to divide this polygon into any numbers of sub polygon (like 20 sub-polygon, 329 sub-polygon, more or less in number). e.g., showing following image, I divide it into 20 sub-polygon but the area of all 20 sub-polygon is equal.

I have area of all 20 sub-polygon e.g., ( 2900312, 7100312, 4900312, 8500456, and so on)hectare.

I want to divide this major polygon into any number of irregular sub polygon according to the given area not in equal. How can I divide it?

I am trying to do it in QGIS using polygon divider plugin, also in ArcGIS. Also trying in PostGIS using K-mean Cluster function but didn't get desired result.

Answer 1

ST_Subdivide it:

Divides geometry into parts using rectilinear lines, until each part can be represented using no more than max_vertices

select st_subdivide(geometry, 200) as geom
from "your_table"
