fullsegments = floor(columns/spacing);
partialsegment = columns - fullsegments * spacing;
segmentwidths = spacing * ones(1,fullsegments);
if partialsegment > 0
  segmentwidths(end+1) = partialsegment;
end
segments = mat2cell(BinaryImage, rows, segmentwidths);

Now segments{1}, segments{2} and so on will be the portions between where the lines would be. If the spacing did not exactly divide the number of columns then the segments{end} will be width less than spacing.

Your code has

rectangle('Position',[value 3 2 40],'facecolor','g');

so you do know where the rectangles are going. They are going at row 3, column "value", width 2, height 40. If you prefer to work in the coordinates above, call imcrop() passing in that same vector you are passing in as your Position.
