Division inside an array

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

oh thank you very much. another small favour please. is there anyway to get modulus of these answers in a matrix like this. what i need is to find the modulus of these divisions and find whether they are equal to 0 or greater than 0. thank you

[Stephen23]

Use mod, e.g.:

M = bsxfun(@rdivide,j(:),fri);
mod(M,2)==0

[Mohamed Musni]

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

[Pawel Jastrzebski]

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

result  = j./fri

please

 can guide me how to get this matrix
