I have an array of 19361 samples. i want to divide it such that each array has 365 samples. 19361 is not perfactly divisible by 365. How can I do that?

Depends. What do you want to do for the leftovers? How will this be used downstream in your code?

Thanks for the reply. I want to keep the leftovers and store them. there are 53 full array and leftocvers should be stored in 54th array.

Here's how to partition your row or column vector of data into a matrix with 365 rows and m columns. The last column may contain trailing NaN values as fillers.
% Create data
data = rand(1,19361);
n = 365; %number of elements per group
% add NaNs to the end of your data to
% create enough samples to split evenly
% into n-sample groups.
extraNeeded = n - mod(numel(data),n);
% Concatenate vertically
% if data is a row vector it will be changed to a column vector
data = [data(:); nan(extraNeeded,1)];
% partition your data
dataSections = reshape(data,n,[]);
Result
size(dataSections)
ans =
365 54
Group j can be accessed by
dataSections(:,j)
