Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times9}403\\\underline{\times\phantom{99}21}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 403 with 1. Write the result 403 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9}403\\\underline{\times\phantom{99}21}\\\phantom{\times9}403\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 403 with 2. Write the result 806 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9}403\\\underline{\times\phantom{99}21}\\\phantom{\times9}403\\\underline{\phantom{\times}806\phantom{9}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times9}403\\\underline{\times\phantom{99}21}\\\phantom{\times9}403\\\underline{\phantom{\times}806\phantom{9}}\\\phantom{\times}8463\end{array}$$
