In this thesis, theory calculations for the triple-differential Z+jet cross section are presented that are suitable for PDF fits with CMS data from the LHC at $\sqrt{s} = 13\,\text{TeV}$. These calculations are performed at NNLO and provided in the form of interpolation grids. An implementation of an automated pipeline for the creation of interpolation grids is offered and was used for this analysis. The cross section is presented as a function of the transverse Z boson momentum $p_\mathrm{T}^\mathrm{Z}$, two rapidity variables $y_\mathrm{b}$ and $y^*$ of the Z+jet system, and an angular variable $\phi^*_\eta$ of the dimuon system. An analysis is performed on the resulting interpolation quality and the contribution of different partonic channels to the cross section. (migrated from EKP Invenio record 49067)
