\begin{array}{c}\phantom{\times99}793\\\underline{\times\phantom{999}27}\\\end{array}

First line up the numbers vertically and match the places from the right like this.

\begin{array}{c}\phantom{\times99}793\\\underline{\times\phantom{999}27}\\\phantom{\times9}5551\\\end{array}

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 793 with 7. Write the result 5551 at the end leaving 0 spaces to the right like this.

\begin{array}{c}\phantom{\times99}793\\\underline{\times\phantom{999}27}\\\phantom{\times9}5551\\\underline{\phantom{\times}1586\phantom{9}}\\\end{array}

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 793 with 2. Write the result 1586 at the end leaving 1 spaces to the right like this.

\begin{array}{c}\phantom{\times99}793\\\underline{\times\phantom{999}27}\\\phantom{\times9}5551\\\underline{\phantom{\times}1586\phantom{9}}\\\phantom{\times}21411\end{array}

Now add the intermediate results to get final answer.
