first, when you write the expressions down to divide them, make sure
to include _every_ power of x. if there is a power missing in the
given problem, fill it in with a 0 to hold that place. for example,
if you were dividing x - 1 into 2x^3 + x - 5, you'd write it like this:
x - 1 ) 2x^3 + 0x^2 + 1x - 5
it is five digits
the term 1/345 is the 50th term.
