Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}23685\\\underline{\times\phantom{99999}84}\\\end{array}$$

Now multiply the first number with the $1^{st}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 23685 with 4. Write the result 94740 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}23685\\\underline{\times\phantom{99999}84}\\\phantom{\times99}94740\\\end{array}$$

Now multiply the first number with the $2^{nd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 23685 with 8. Write the result 189480 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}23685\\\underline{\times\phantom{99999}84}\\\phantom{\times99}94740\\\underline{\phantom{\times}189480\phantom{9}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}23685\\\underline{\times\phantom{99999}84}\\\phantom{\times99}94740\\\underline{\phantom{\times}189480\phantom{9}}\\\phantom{\times}1989540\end{array}$$
