Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}3812\\\underline{\times\phantom{999}258}\\\end{array}$$

Now multiply the first number with the $1^{st}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 3812 with 8. Write the result 30496 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}3812\\\underline{\times\phantom{999}258}\\\phantom{\times9}30496\\\end{array}$$

Now multiply the first number with the $2^{nd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 3812 with 5. Write the result 19060 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}3812\\\underline{\times\phantom{999}258}\\\phantom{\times9}30496\\\phantom{\times}19060\phantom{9}\\\end{array}$$

Now multiply the first number with the $3^{rd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 3812 with 2. Write the result 7624 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}3812\\\underline{\times\phantom{999}258}\\\phantom{\times9}30496\\\phantom{\times}19060\phantom{9}\\\underline{\phantom{\times}7624\phantom{99}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}3812\\\underline{\times\phantom{999}258}\\\phantom{\times9}30496\\\phantom{\times}19060\phantom{9}\\\underline{\phantom{\times}7624\phantom{99}}\\\phantom{\times}983496\end{array}$$
