Compute 10^785 mod 23

I don't want the solution right away but could someone please point me in the right direction? I know there must be some trick to somehow 'cancel' the huge exponent but I don't know how to play with it.

Damn, I messed up the tags again. Final version (I hope!):

10⁷⁸⁵ = 10^(23·34)+3 = 10^23·34 · 10³ = (10²³)³⁴ · 10³

As 23 is prime, x²³ mod 23 is 1 for all non-zero x. So:

(10²³)³⁴ · 10³ = 1³⁴ · 10³ = 10³ mod 23 = 1000 mod 23 = 8
