Steps For Long Multiplication

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

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

Now multiply the first number with the $1^{st}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 9999 with 9. Write the result 89991 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9999}9999\\\underline{\times\phantom{9999}9999}\\\phantom{\times999}89991\\\end{array}$$

Now multiply the first number with the $2^{nd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 9999 with 9. Write the result 89991 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9999}9999\\\underline{\times\phantom{9999}9999}\\\phantom{\times999}89991\\\phantom{\times99}89991\phantom{9}\\\end{array}$$

Now multiply the first number with the $3^{rd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 9999 with 9. Write the result 89991 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9999}9999\\\underline{\times\phantom{9999}9999}\\\phantom{\times999}89991\\\phantom{\times99}89991\phantom{9}\\\phantom{\times9}89991\phantom{99}\\\end{array}$$

Now multiply the first number with the $4^{th}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 9999 with 9. Write the result 89991 at the end leaving 3 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9999}9999\\\underline{\times\phantom{9999}9999}\\\phantom{\times999}89991\\\phantom{\times99}89991\phantom{9}\\\phantom{\times9}89991\phantom{99}\\\underline{\phantom{\times}89991\phantom{999}}\\\end{array}$$

Now add the intermediate results to get final answer.
