Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99999}64\\\underline{\times\phantom{99}15625}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 64 with 5. Write the result 320 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99999}64\\\underline{\times\phantom{99}15625}\\\phantom{\times9999}320\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 64 with 2. Write the result 128 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99999}64\\\underline{\times\phantom{99}15625}\\\phantom{\times9999}320\\\phantom{\times999}128\phantom{9}\\\end{array}$$

Now multiply the first number with the 3^{rd} digit in 2^{nd} number to get intermediate results. That is Multiply 64 with 6. Write the result 384 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99999}64\\\underline{\times\phantom{99}15625}\\\phantom{\times9999}320\\\phantom{\times999}128\phantom{9}\\\phantom{\times99}384\phantom{99}\\\end{array}$$

Now multiply the first number with the 4^{th} digit in 2^{nd} number to get intermediate results. That is Multiply 64 with 5. Write the result 320 at the end leaving 3 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99999}64\\\underline{\times\phantom{99}15625}\\\phantom{\times9999}320\\\phantom{\times999}128\phantom{9}\\\phantom{\times99}384\phantom{99}\\\phantom{\times9}320\phantom{999}\\\end{array}$$

Now multiply the first number with the 5^{th} digit in 2^{nd} number to get intermediate results. That is Multiply 64 with 1. Write the result 64 at the end leaving 4 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99999}64\\\underline{\times\phantom{99}15625}\\\phantom{\times9999}320\\\phantom{\times999}128\phantom{9}\\\phantom{\times99}384\phantom{99}\\\phantom{\times9}320\phantom{999}\\\underline{\phantom{\times9}64\phantom{9999}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99999}64\\\underline{\times\phantom{99}15625}\\\phantom{\times9999}320\\\phantom{\times999}128\phantom{9}\\\phantom{\times99}384\phantom{99}\\\phantom{\times9}320\phantom{999}\\\underline{\phantom{\times9}64\phantom{9999}}\\\phantom{\times}1000000\end{array}$$
