Installing CUDA toolkit on debian linux 10 (buster)

Hi!
I am trying to install the CUDA toolkit on debian linux 10 (buster). My graphics card is GeForce GT 610 which have support for Nvidia-390.xx, therefore I have chosen CUDA 9.0. When installing with the local deb file I get the message: The following packages have unmet dependencies:
cuda : Depends: cuda-9-0 (>= 9.0.176) but it is not going to be installed
E: Unable to correct problems, you have held broken packages. I have tried fixing it with aptitude but it still will not install. What am I doing wrong and is there any way to install the CUDA toolkit on debian?
