                        Next, we divide 5 by 3,

                                                          5= 3+ 2.


                        The remainder


                                                          2= 5 − 3.


                        Substituting our equations for 5 and 3,


                           2= 5 − 3= (4)103 +(−11)37 − [(−5)103 +(14)37] =(9)103 +(−25)37.


                        Finally, we divide the last two remainders,



                                                          3= 2+ 1.

                        The last remainder

                                                          1= 3 − 2.



                        Substituting our equations for 3 and 2,
