This problem is not common, but not unheard of. The teeth on the starter drive gear are worn. Replacing this gear may (or may not) solve your problem. Because of the grinding, the teeth on the flywheel ring gear are also likely to be worn. New teeth on the starter gear may be enough to engage the flywheel properly, so you can get a few more (dozen) years from your car.
If the flywheel teeth are too worn, however, you must remove the tranny to fix the flywheel. Fortunately, a quick fix is possible. Because a 4-cylinder engine ALWAYS stops in one of two positions (180 degrees apart), only two spots on the ring gear will be hammered. You can remove the flywheel (or flexplate) from the 8-bolt crank, turn it 90-degrees relative to the crank, and re-bolt it. Now the bad teeth are completely out of the way and will not interfer with initial engagement.
If you must remove the flywheel, BE SURE to take the time to install a new rear main engine seal.
