Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}255\\\underline{\times\phantom{99}306}\\\end{array}$$

Now multiply the first number with the $1^{st}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 255 with 6. Write the result 1530 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}255\\\underline{\times\phantom{99}306}\\\phantom{\times9}1530\\\end{array}$$

Now multiply the first number with the $2^{nd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 255 with 0. Write the result 0 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}255\\\underline{\times\phantom{99}306}\\\phantom{\times9}1530\\\phantom{\times9999}0\phantom{9}\\\end{array}$$

Now multiply the first number with the $3^{rd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 255 with 3. Write the result 765 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}255\\\underline{\times\phantom{99}306}\\\phantom{\times9}1530\\\phantom{\times9999}0\phantom{9}\\\underline{\phantom{\times}765\phantom{99}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}255\\\underline{\times\phantom{99}306}\\\phantom{\times9}1530\\\phantom{\times9999}0\phantom{9}\\\underline{\phantom{\times}765\phantom{99}}\\\phantom{\times}78030\end{array}$$
