Yu gotta hav more rules than that. 50^7 is a number, so yukan . . . divide NE number yu kan thank av intu NE other number yukan . . . thank av. . . . yu also menshun 5^n....perhaps yu divide thin intu 50^7????? . . . so yukan divide 5^n intu NE number for evree n yu kan thank av. . . . 5^99999 is a number. so yukan divide it intu nuther number. . . . Perhaps yu want a frakshun that dont hav NE LEFTOVER.... Zampel...50/5=10...leftover=0. look good. . . . Then tri 50/5^2=50/25...leftover=0. Then 50/5^3=50/125=0.4, , , that hav leftover > 0.....
