Euclidean division says a = bq + r, where q is the quotient, r is the remainder, b is dividend and in our problem a = p, therefore
\n" ); document.write( "p = 9b + 7
\n" ); document.write( "now with b = 1, then p = 16
\n" ); document.write( "now b = 3
\n" ); document.write( "16 = 5*3 +r
\n" ); document.write( "r = 16 - 15 = 1
\n" ); document.write( " \n" ); document.write( "

\n" );
