How to draw graph after dividing two set of points?

Dear Experts,
I have two sets of numbers, Data = (34,54,25,28), errors are(5,6,4,6).
MC = (56,34,58,14), errors are (7,6,9,3).
I want to plot a graph after dividing each number from each bin. I can draw a tgraph for one set of numbers by following this code. Could you please suggest me what should I add to do that operation ?

Thanks in Advance.

{
   auto c1 = new TCanvas("c4","c4",200,0,600,400);
   c1->DrawFrame(0.05,0,0.34,12000);
   double x[] = {0.1, 0.15, 0.21, 0.32};
   double y[] = {2168,8859,6347,7602};
   double ex[] = {0, 0, 0, 0, 0};
   double ey[] = {238,302,280,385};
   auto ge = new TGraphErrors(4, x, y, ex, ey);
   ge->SetMarkerStyle(20);
   ge->Draw("P");
   //ge->Draw("AL");

   c1->Update();
   //c1->GetFrame()->SetFillColor(1);
   c1->GetFrame()->SetBorderSize(12);
   c1->Modified();

   ge->GetXaxis()->SetTitle("Momentum");
   ge->GetYaxis()->SetTitle("Yield");

}

Simply do by looping over the arrays x and y and perform the operation you need.
