How do you want to divide the image? Do you want 3 blocks horizontally and 2 blocks vertically or some other arrangement?

Any arrangement but all should be equally divided.

This code shows one example. However, this will only work if the number of pixels in the image can be evenly divided into blocks
I = imread('pears.png');
blocks = mat2cell(I, size(I,1)/2*ones(1,2), size(I,2)/3*ones(1,3), 3);
count = 1;
for i=1:size(blocks,1)
for j=1:size(blocks,2)
subplot(2,3,count)
imshow(blocks{i,j});
count = count + 1;
end
end

It seems that the number of pixels in row and column of your images cannot be evenly divided. Is it acceptable if a few pixels are ignored? At maximum, only 1-2 lines of pixels will be deleted.

You can use blockproc(). See attached demos.
