+       [2 0 2]
+   , 127 in base 126 will be:
+       [1 1]
+   and so on.
+
+   We will use the sucessive division method: do a integer division of the number
+   to the base until the quotient is zero, and take the reminders backwards. For
+   example, if we want to converto 127 to base 5:
+
+       127 / 5 = 25 rem 2
+        25 / 5 =  5 rem 0
+         5 / 5 =  1 rem 0
+         1 / 5 =  0 rem 1
+   
+   so, 127 in base 5 is 1002.
+
+   The maximum digits this method can return is 65. Max size for a long is base 2
+   is 64, so if you obtain a result with 65 digits is very probable that the
+   conversion has failed.
+
+   If the number is negative and the base is possitive, we return the conversion
+   of the absolute value. You must take care of the sign in your implementation.
+
