Sure Angela,
 Take the original decimal (base ten) number and call it A.
 Put a spot on your paper where you will write the equivalent base 5 number from left to right.
 Divide A by 5 into a quotient Q and a remainder R.
 Write the remainder R down in the first (ones) column for the base 5 equivalent.
 Now let A take on the value of Q.
 Divide A by 5 into a new quotient Q and a new remainder R.
 Write the remainder R down in the next (working leftwards) column for the base 5 equivalent.
 Repeat from step 5 until A is zero.
Example: 419 in base 10.
419 ÷ 5 = 83 r 4, so Base 5 is now: _ _ _ 4.
83 ÷ 5 = 16 r 3, so Base 5 is now: _ _ 3 4.
16 ÷ 5 = 3 r 1, so Base 5 is now: _ 1 3 4.
3 ÷ 5 = 0 r 3, so Base 5 is now: 3 1 3 4.
So 419 in base 10 is 3134 in base 5.
Cheers,
Stephen La Rocque.
