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

$$\begin{array}{c}\phantom{\times9999999}123\\\underline{\times\phantom{99}11111111}\\\end{array}$$

Now multiply the first number with the $1^{st}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 123 with 1. Write the result 123 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9999999}123\\\underline{\times\phantom{99}11111111}\\\phantom{\times9999999}123\\\end{array}$$

Now multiply the first number with the $2^{nd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 123 with 1. Write the result 123 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9999999}123\\\underline{\times\phantom{99}11111111}\\\phantom{\times9999999}123\\\phantom{\times999999}123\phantom{9}\\\end{array}$$

Now multiply the first number with the $3^{rd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 123 with 1. Write the result 123 at the end leaving 2 spaces to the right like this.

Now multiply the first number with the $4^{th}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 123 with 1. Write the result 123 at the end leaving 3 spaces to the right like this.

Now multiply the first number with the $5^{th}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 123 with 1. Write the result 123 at the end leaving 4 spaces to the right like this.

Now multiply the first number with the $6^{th}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 123 with 1. Write the result 123 at the end leaving 5 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9999999}123\\\underline{\times\phantom{99}11111111}\\\phantom{\times9999999}123\\\phantom{\times999999}123\phantom{9}\\\phantom{\times99999}123\phantom{99}\\\phantom{\times9999}123\phantom{999}\\\phantom{\times999}123\phantom{9999}\\\phantom{\times99}123\phantom{99999}\\\end{array}$$

Now multiply the first number with the $7^{th}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 123 with 1. Write the result 123 at the end leaving 6 spaces to the right like this.

Now multiply the first number with the $8^{th}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 123 with 1. Write the result 123 at the end leaving 7 spaces to the right like this.

Now add the intermediate results to get final answer.
