Step number 3 is to compare the number 33 with the given number. Below is code in C++ where you can check it.
#include<iostream>
using namespace std;
int main()
{
  int step,n,half,first,last,ext;
  int list[] = {1,2,3,4,10,11,16,25,32,33,45,47,51,69,75};
  first = 0;
  last = 14;
  ext = 0;
  step = 0;
  cout<< "Entry number to find: ";
  cin>> n;
  while (first <= last and ext == 0)
  {
    half = (first+last)/2;
    step=step+1;
    cout << "Step: " << step;
    cout << " Compare the number " << list[half] << " with "  << n <<endl;
    if (n == list[half])
      ext = 1;
    if (n < list[half])
      last=half-1;
    if (n > list[half])
      first=half+1;
  }
