550÷11=50 And here 5^2 +5^2 +0^2 =50  find another three digit number  which is divisible by 11 and the  quotient is the sum of the    square of  the every digit of   the dividend.    /

242/11=22  2^2 +4^2 +2^2 =24≠22 !
$$\mathrm{242}/\mathrm{11}=\mathrm{22} \\ $$$$\mathrm{2}^{\mathrm{2}} +\mathrm{4}^{\mathrm{2}} +\mathrm{2}^{\mathrm{2}} =\mathrm{24}\neq\mathrm{22}\:! \\ $$
