Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times999}42\\\underline{\times\phantom{99}456}\\\end{array}$$

Now multiply the first number with the $1^{st}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 42 with 6. Write the result 252 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}42\\\underline{\times\phantom{99}456}\\\phantom{\times99}252\\\end{array}$$

Now multiply the first number with the $2^{nd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 42 with 5. Write the result 210 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}42\\\underline{\times\phantom{99}456}\\\phantom{\times99}252\\\phantom{\times9}210\phantom{9}\\\end{array}$$

Now multiply the first number with the $3^{rd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 42 with 4. Write the result 168 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}42\\\underline{\times\phantom{99}456}\\\phantom{\times99}252\\\phantom{\times9}210\phantom{9}\\\underline{\phantom{\times}168\phantom{99}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times999}42\\\underline{\times\phantom{99}456}\\\phantom{\times99}252\\\phantom{\times9}210\phantom{9}\\\underline{\phantom{\times}168\phantom{99}}\\\phantom{\times}19152\end{array}$$
