Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-3" was replaced by "^(-3)".

(2): ".494" was replaced by "(494/1000)".

Step  1  :

            247
 Simplify   ———
            500

Equation at the end of step  1  :

                 247
  (1 • (10-3)) • ———
                 500

Step  2  :

 2.1     10 = 2•5

(10)^-3 = (2•5)^(-3) = (2)^(-3) • (5)^(-3)

Equation at the end of step  2  :

                            247
  (1 • ((2)(-3)•(5)(-3))) • ———
                            500

Step  3  :

Final result :

    247            
  —————— = 0.00049
