\begin{array}{c}\phantom{\times9}19\\\underline{\times\phantom{9}12}\\\end{array}
First line up the numbers vertically and match the places from the right like this.
\begin{array}{c}\phantom{\times9}19\\\underline{\times\phantom{9}12}\\\phantom{\times9}38\\\end{array}
Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 19 with 2. Write the result 38 at the end leaving 0 spaces to the right like this.
\begin{array}{c}\phantom{\times9}19\\\underline{\times\phantom{9}12}\\\phantom{\times9}38\\\underline{\phantom{\times}19\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 19 with 1. Write the result 19 at the end leaving 1 spaces to the right like this.
\begin{array}{c}\phantom{\times9}19\\\underline{\times\phantom{9}12}\\\phantom{\times9}38\\\underline{\phantom{\times}19\phantom{9}}\\\phantom{\times}228\end{array}
Now add the intermediate results to get final answer.
