\r\n" );
document.write( "    The remainder of divisibility by 9 of the number N is the same,\r\n" );
document.write( "    as the remainder of the sum of digits of the number N when divided by 9.\r\n" );
document.write( "

\r
\n" ); document.write( "\n" ); document.write( "

\r\n" );
document.write( "The number  274563358  has the sum of its digits  2+7+4+5+6+3+3+5+8 = 43.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, the number 274563358  itself,  when divided by 9, gives the same remainder \r\n" );
document.write( "as the sum of its digits 43 divided by 9, i.e. 43 mod 9 = 7.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence,  when divided by 9 gives the same remainder as the number  = 16807 when divided by 9.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Again, the number 16807 has the sum of the digits  1+6+8+7 = 22.\r\n" );
document.write( "\r\n" );
document.write( "Therefore, the answer to the problem's question is 22 mod 9 = 4.\r\n" );
