Extremely easy. Just look at your image format setting and your card size, then consult the chart on page 362 of your D850 User's Manual. That chart uses a 64GB card as their example capacity. The 12-bit compressed NEF files in the full 8256x5504 pixel resolution stores about 800 image files per 64GB. Just determine your own simple (round number) math for your card size and camera settings.
