$$\begin{array}{c}\phantom{\times99999}99999\\\underline{\times\phantom{99999}99998}\\\phantom{\times9999}799992\\\phantom{\times999}899991\phantom{9}\\\end{array}$$

Now multiply the first number with the 3^{rd} digit in 2^{nd} number to get intermediate results. That is Multiply 99999 with 9. Write the result 899991 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99999}99999\\\underline{\times\phantom{99999}99998}\\\phantom{\times9999}799992\\\phantom{\times999}899991\phantom{9}\\\phantom{\times99}899991\phantom{99}\\\end{array}$$

Now multiply the first number with the 4^{th} digit in 2^{nd} number to get intermediate results. That is Multiply 99999 with 9. Write the result 899991 at the end leaving 3 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99999}99999\\\underline{\times\phantom{99999}99998}\\\phantom{\times9999}799992\\\phantom{\times999}899991\phantom{9}\\\phantom{\times99}899991\phantom{99}\\\phantom{\times9}899991\phantom{999}\\\end{array}$$

Now multiply the first number with the 5^{th} digit in 2^{nd} number to get intermediate results. That is Multiply 99999 with 9. Write the result 899991 at the end leaving 4 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99999}99999\\\underline{\times\phantom{99999}99998}\\\phantom{\times9999}799992\\\phantom{\times999}899991\phantom{9}\\\phantom{\times99}899991\phantom{99}\\\phantom{\times9}899991\phantom{999}\\\underline{\phantom{\times}899991\phantom{9999}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99999}99999\\\underline{\times\phantom{99999}99998}\\\phantom{\times9999}799992\\\phantom{\times999}899991\phantom{9}\\\phantom{\times99}899991\phantom{99}\\\phantom{\times9}899991\phantom{999}\\\underline{\phantom{\times}899991\phantom{9999}}\\\phantom{\times}1409765410\end{array}$$
