Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}256\\\underline{\times\phantom{99}256}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 256 with 6. Write the result 1536 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}256\\\underline{\times\phantom{99}256}\\\phantom{\times9}1536\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 256 with 5. Write the result 1280 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}256\\\underline{\times\phantom{99}256}\\\phantom{\times9}1536\\\phantom{\times}1280\phantom{9}\\\end{array}$$

Now multiply the first number with the 3^{rd} digit in 2^{nd} number to get intermediate results. That is Multiply 256 with 2. Write the result 512 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}256\\\underline{\times\phantom{99}256}\\\phantom{\times9}1536\\\phantom{\times}1280\phantom{9}\\\underline{\phantom{\times}512\phantom{99}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}256\\\underline{\times\phantom{99}256}\\\phantom{\times9}1536\\\phantom{\times}1280\phantom{9}\\\underline{\phantom{\times}512\phantom{99}}\\\phantom{\times}65536\end{array}$$
