Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times9999}7777\\\underline{\times\phantom{9999}7777}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 7777 with 7. Write the result 54439 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9999}7777\\\underline{\times\phantom{9999}7777}\\\phantom{\times999}54439\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 7777 with 7. Write the result 54439 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9999}7777\\\underline{\times\phantom{9999}7777}\\\phantom{\times999}54439\\\phantom{\times99}54439\phantom{9}\\\end{array}$$

Now multiply the first number with the 3^{rd} digit in 2^{nd} number to get intermediate results. That is Multiply 7777 with 7. Write the result 54439 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9999}7777\\\underline{\times\phantom{9999}7777}\\\phantom{\times999}54439\\\phantom{\times99}54439\phantom{9}\\\phantom{\times9}54439\phantom{99}\\\end{array}$$

Now multiply the first number with the 4^{th} digit in 2^{nd} number to get intermediate results. That is Multiply 7777 with 7. Write the result 54439 at the end leaving 3 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9999}7777\\\underline{\times\phantom{9999}7777}\\\phantom{\times999}54439\\\phantom{\times99}54439\phantom{9}\\\phantom{\times9}54439\phantom{99}\\\underline{\phantom{\times}54439\phantom{999}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times9999}7777\\\underline{\times\phantom{9999}7777}\\\phantom{\times999}54439\\\phantom{\times99}54439\phantom{9}\\\phantom{\times9}54439\phantom{99}\\\underline{\phantom{\times}54439\phantom{999}}\\\phantom{\times}60481729\end{array}$$
