Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}42\\\underline{\times\phantom{99}42}\\\end{array}$$

Now multiply the first number with the $1^{st}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 42 with 2. Write the result 84 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}42\\\underline{\times\phantom{99}42}\\\phantom{\times99}84\\\end{array}$$

Now multiply the first number with the $2^{nd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 42 with 4. Write the result 168 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}42\\\underline{\times\phantom{99}42}\\\phantom{\times99}84\\\underline{\phantom{\times}168\phantom{9}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}42\\\underline{\times\phantom{99}42}\\\phantom{\times99}84\\\underline{\phantom{\times}168\phantom{9}}\\\phantom{\times}1764\end{array}$$
