a$)$ Input $2$ positive numbers, the first one is the Dividend, and the second one is the Divisor b$)$ If they do not evenly divide, then the program outputs the Residue and asks to input two new numbers c$)$ If they evenly divide, then the program outputs the Quotient and asks to input two new numbers d$)$ When the Dividend entered is $999$ the program will output $999$ and stop. e$)$ If the Divisor is larger than the Dividend, your program will switch them and proceed to point b$)$
