Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}31\\\underline{\times\phantom{9}125}\\\end{array}$$

Now multiply the first number with the $1^{st}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 31 with 5. Write the result 155 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}31\\\underline{\times\phantom{9}125}\\\phantom{\times9}155\\\end{array}$$

Now multiply the first number with the $2^{nd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 31 with 2. Write the result 62 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}31\\\underline{\times\phantom{9}125}\\\phantom{\times9}155\\\phantom{\times9}62\phantom{9}\\\end{array}$$

Now multiply the first number with the $3^{rd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 31 with 1. Write the result 31 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}31\\\underline{\times\phantom{9}125}\\\phantom{\times9}155\\\phantom{\times9}62\phantom{9}\\\underline{\phantom{\times}31\phantom{99}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}31\\\underline{\times\phantom{9}125}\\\phantom{\times9}155\\\phantom{\times9}62\phantom{9}\\\underline{\phantom{\times}31\phantom{99}}\\\phantom{\times}3875\end{array}$$
