If you're looking just to resolve your issue, have you tried using any of the free subnet calculators found on the Internet?

Is your question more about understanding how to subdivide a network?

The question doesn't give enough information but if subnetting 10.10.93.0 into a Class C, you could use a subnet mask of 255.255.255.192 (/26) which would give you 4 equal subnets with 62 usable addresses in each.
