Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times999}789\\\underline{\times\phantom{999}455}\\\end{array}$$

Now multiply the first number with the $1^{st}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 789 with 5. Write the result 3945 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}789\\\underline{\times\phantom{999}455}\\\phantom{\times99}3945\\\end{array}$$

Now multiply the first number with the $2^{nd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 789 with 5. Write the result 3945 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}789\\\underline{\times\phantom{999}455}\\\phantom{\times99}3945\\\phantom{\times9}3945\phantom{9}\\\end{array}$$

Now multiply the first number with the $3^{rd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 789 with 4. Write the result 3156 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}789\\\underline{\times\phantom{999}455}\\\phantom{\times99}3945\\\phantom{\times9}3945\phantom{9}\\\underline{\phantom{\times}3156\phantom{99}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times999}789\\\underline{\times\phantom{999}455}\\\phantom{\times99}3945\\\phantom{\times9}3945\phantom{9}\\\underline{\phantom{\times}3156\phantom{99}}\\\phantom{\times}358995\end{array}$$
