Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times999999}100\\\underline{\times\phantom{99}5000000}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 100 with 0. Write the result 0 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999999}100\\\underline{\times\phantom{99}5000000}\\\phantom{\times999999999}0\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 100 with 0. Write the result 0 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999999}100\\\underline{\times\phantom{99}5000000}\\\phantom{\times999999999}0\\\phantom{\times99999999}0\phantom{9}\\\end{array}$$

Now multiply the first number with the 3^{rd} digit in 2^{nd} number to get intermediate results. That is Multiply 100 with 0. Write the result 0 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999999}100\\\underline{\times\phantom{99}5000000}\\\phantom{\times999999999}0\\\phantom{\times99999999}0\phantom{9}\\\phantom{\times9999999}0\phantom{99}\\\end{array}$$

Now multiply the first number with the 4^{th} digit in 2^{nd} number to get intermediate results. That is Multiply 100 with 0. Write the result 0 at the end leaving 3 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999999}100\\\underline{\times\phantom{99}5000000}\\\phantom{\times999999999}0\\\phantom{\times99999999}0\phantom{9}\\\phantom{\times9999999}0\phantom{99}\\\phantom{\times999999}0\phantom{999}\\\end{array}$$

Now multiply the first number with the 5^{th} digit in 2^{nd} number to get intermediate results. That is Multiply 100 with 0. Write the result 0 at the end leaving 4 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999999}100\\\underline{\times\phantom{99}5000000}\\\phantom{\times999999999}0\\\phantom{\times99999999}0\phantom{9}\\\phantom{\times9999999}0\phantom{99}\\\phantom{\times999999}0\phantom{999}\\\phantom{\times99999}0\phantom{9999}\\\end{array}$$

Now multiply the first number with the 6^{th} digit in 2^{nd} number to get intermediate results. That is Multiply 100 with 0. Write the result 0 at the end leaving 5 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999999}100\\\underline{\times\phantom{99}5000000}\\\phantom{\times999999999}0\\\phantom{\times99999999}0\phantom{9}\\\phantom{\times9999999}0\phantom{99}\\\phantom{\times999999}0\phantom{999}\\\phantom{\times99999}0\phantom{9999}\\\phantom{\times9999}0\phantom{99999}\\\end{array}$$

Now multiply the first number with the 7^{th} digit in 2^{nd} number to get intermediate results. That is Multiply 100 with 5. Write the result 500 at the end leaving 6 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999999}100\\\underline{\times\phantom{99}5000000}\\\phantom{\times999999999}0\\\phantom{\times99999999}0\phantom{9}\\\phantom{\times9999999}0\phantom{99}\\\phantom{\times999999}0\phantom{999}\\\phantom{\times99999}0\phantom{9999}\\\phantom{\times9999}0\phantom{99999}\\\underline{\phantom{\times}500\phantom{999999}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times999999}100\\\underline{\times\phantom{99}5000000}\\\phantom{\times999999999}0\\\phantom{\times99999999}0\phantom{9}\\\phantom{\times9999999}0\phantom{99}\\\phantom{\times999999}0\phantom{999}\\\phantom{\times99999}0\phantom{9999}\\\phantom{\times9999}0\phantom{99999}\\\underline{\phantom{\times}500\phantom{999999}}\\\phantom{\times}500000000\end{array}$$

Factor

$$2^{8}\times 5^{9}$$
