Cannot get mod to return correct value

I am trying to solve:
In Matlab, mod(3^233,353) = 92
But the correct answer is 248.
Is the number to large? Is this a configuration issue? Is there not enough digits being kept for the calculation? Do I need to do this another way?

3^233 is an integer. Its value is roughly 1.5e111. So it needs 112 digits to record the integer value accurately. Double-precision data can't do that. I don't think MATLAB is the right tool for this.
