Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times9999}400\\\underline{\times\phantom{999}2820}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 400 with 0. Write the result 0 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9999}400\\\underline{\times\phantom{999}2820}\\\phantom{\times9999999}0\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 400 with 2. Write the result 800 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9999}400\\\underline{\times\phantom{999}2820}\\\phantom{\times9999999}0\\\phantom{\times999}800\phantom{9}\\\end{array}$$

Now multiply the first number with the 3^{rd} digit in 2^{nd} number to get intermediate results. That is Multiply 400 with 8. Write the result 3200 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9999}400\\\underline{\times\phantom{999}2820}\\\phantom{\times9999999}0\\\phantom{\times999}800\phantom{9}\\\phantom{\times9}3200\phantom{99}\\\end{array}$$

Now multiply the first number with the 4^{th} digit in 2^{nd} number to get intermediate results. That is Multiply 400 with 2. Write the result 800 at the end leaving 3 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9999}400\\\underline{\times\phantom{999}2820}\\\phantom{\times9999999}0\\\phantom{\times999}800\phantom{9}\\\phantom{\times9}3200\phantom{99}\\\underline{\phantom{\times9}800\phantom{999}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times9999}400\\\underline{\times\phantom{999}2820}\\\phantom{\times9999999}0\\\phantom{\times999}800\phantom{9}\\\phantom{\times9}3200\phantom{99}\\\underline{\phantom{\times9}800\phantom{999}}\\\phantom{\times}1128000\end{array}$$
