these are the two arrays i have

fri =

1 2 3

j =

     0     1     2     3     4     5     6
i want to divide each element inside fri by one value of j at once. ex : 1/0,2/0,3/0 after that 1/1,2/1/3/1 and so on.
when i perform Xij = j./fri it gives an error that matrix sizes must be equal.(logically this is wrong as i see). is there any way to perform this operation and get values? any help will be highly appreciated.

>> fri = 1:3;
>> j = 0:6;
>> bsxfun(@rdivide,j(:),fri)
ans =
   0.00000   0.00000   0.00000
   1.00000   0.50000   0.33333
   2.00000   1.00000   0.66667
   3.00000   1.50000   1.00000
   4.00000   2.00000   1.33333
   5.00000   2.50000   1.66667
   6.00000   3.00000   2.00000

accordingly i need to get a matrix with 0 and 1. if no remainder for the division output is 1 and if there is an remainder output is 0. any help i will be thankful because this is my last part of my thesis and i got bit stuck. thank you

fri = 1:3
j = 0:6
j = j'

result  = j./fri
