The columns on the front of this almirah are not placed by dividing the width into equal parts. They are placed by geometry, and getting them wrong would ruin the outline.
Each bowed end is an arc. That arc has to run out and become the flat front of the cabinet, and there is exactly one point where it does so smoothly - the tangent point, where the curve is already travelling in the same direction as the straight section it meets. Put the dividing column an inch inside that point and the curve is cut off before it has finished, leaving a visible kink at the join. Put it an inch outside and the flat front starts before the column, so a short flat runs where the eye expects curve.
Our artisans find that point on the drawing first and then confirm it on the built carcass with a straightedge laid along the flat front. The straightedge should touch the curve at one place only. Where it does, the column goes.
Everything else - flute spacing, panel widths, apron divisions - is then set out from those column positions, not the other way round.
