May be something like this :

        Mat paste(frame_height, frame_width,CV_8UC3);
        Rect r(0,0,0,0);
        for (int i = 0,k=0; i < 10; i++)
        {
            for (int j = 0; j < 10; j++,k++)
            {
                r.width = divided[i].cols;
                r.height = divided[i].rows;
                divided[k].copyTo(paste(r));
                r.y+= r.height;
            }
            r.y=0;
            r.x+= r.width;
        }
        imshow("paste",paste);
        waitKey(0);

May be something like this :for you puzzle (it is not really image processing but it is funny):

        Mat paste(frame_height, frame_width,CV_8UC3);
        Rect r(0,0,0,0);
        vector<int> pos(100);
        for (int i=0;i<100;i++)
            pos[i]=i;
        RNG rg;
        for (int i = 0; i < 1000; i++)
        {
            int k=rg.uniform(0,100);
            swap(pos[0],pos[k]);
        }
        for (int i = 0,k=0; i < 10; i++)
        {
            for (int j = 0; j < 10; j++,k++)
            {
                r.width = divided[i].cols;
                r.height = divided[i].rows;
                divided[k].copyTo(paste(r));
divided[pos[k]].copyTo(paste(r));
                r.y+= r.height;
            }
            r.y=0;
            r.x+= r.width;
        }
        imshow("paste",paste);
        waitKey(0);
