 This is the only way I know to do this.......  

 

       .370

27 [  100

          81

        ------

           190

           189

          ------

               100

 

Notice, Mellie.....the same pattern would start all over, again.....(and keep repeating )

 

So.....the first ten digits are......... 0.3083083083
