Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}850\\\underline{\times\phantom{999}21}\\\end{array}$$

Now multiply the first number with the $1^{st}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 850 with 1. Write the result 850 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}850\\\underline{\times\phantom{999}21}\\\phantom{\times99}850\\\end{array}$$

Now multiply the first number with the $2^{nd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 850 with 2. Write the result 1700 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}850\\\underline{\times\phantom{999}21}\\\phantom{\times99}850\\\underline{\phantom{\times}1700\phantom{9}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}850\\\underline{\times\phantom{999}21}\\\phantom{\times99}850\\\underline{\phantom{\times}1700\phantom{9}}\\\phantom{\times}17850\end{array}$$
