Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times999}1200\\\underline{\times\phantom{999}1200}\\\end{array}$$

Now multiply the first number with the $1^{st}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 1200 with 0. Write the result 0 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}1200\\\underline{\times\phantom{999}1200}\\\phantom{\times9999999}0\\\end{array}$$

Now multiply the first number with the $2^{nd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 1200 with 0. Write the result 0 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}1200\\\underline{\times\phantom{999}1200}\\\phantom{\times9999999}0\\\phantom{\times999999}0\phantom{9}\\\end{array}$$

Now multiply the first number with the $3^{rd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 1200 with 2. Write the result 2400 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}1200\\\underline{\times\phantom{999}1200}\\\phantom{\times9999999}0\\\phantom{\times999999}0\phantom{9}\\\phantom{\times9}2400\phantom{99}\\\end{array}$$

Now multiply the first number with the $4^{th}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 1200 with 1. Write the result 1200 at the end leaving 3 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}1200\\\underline{\times\phantom{999}1200}\\\phantom{\times9999999}0\\\phantom{\times999999}0\phantom{9}\\\phantom{\times9}2400\phantom{99}\\\underline{\phantom{\times}1200\phantom{999}}\\\end{array}$$

Now add the intermediate results to get final answer.
