Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times}1500000\\\underline{\times\phantom{}13900}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 1500000 with 0. Write the result 0 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times}1500000\\\underline{\times\phantom{}13900}\\\phantom{\times}0\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 1500000 with 0. Write the result 0 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times}1500000\\\underline{\times\phantom{}13900}\\\phantom{\times}0\\\phantom{\times}0\phantom{9}\\\end{array}$$

Now multiply the first number with the 3^{rd} digit in 2^{nd} number to get intermediate results. That is Multiply 1500000 with 9. Write the result 13500000 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times}1500000\\\underline{\times\phantom{}13900}\\\phantom{\times}0\\\phantom{\times}0\phantom{9}\\\phantom{\times}13500000\phantom{99}\\\end{array}$$

Now multiply the first number with the 4^{th} digit in 2^{nd} number to get intermediate results. That is Multiply 1500000 with 3. Write the result 4500000 at the end leaving 3 spaces to the right like this.

$$\begin{array}{c}\phantom{\times}1500000\\\underline{\times\phantom{}13900}\\\phantom{\times}0\\\phantom{\times}0\phantom{9}\\\phantom{\times}13500000\phantom{99}\\\phantom{\times}4500000\phantom{999}\\\end{array}$$

Now multiply the first number with the 5^{th} digit in 2^{nd} number to get intermediate results. That is Multiply 1500000 with 1. Write the result 1500000 at the end leaving 4 spaces to the right like this.

$$\begin{array}{c}\phantom{\times}1500000\\\underline{\times\phantom{}13900}\\\phantom{\times}0\\\phantom{\times}0\phantom{9}\\\phantom{\times}13500000\phantom{99}\\\phantom{\times}4500000\phantom{999}\\\underline{\phantom{\times}1500000\phantom{9999}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times}1500000\\\underline{\times\phantom{}13900}\\\phantom{\times}0\\\phantom{\times}0\phantom{9}\\\phantom{\times}13500000\phantom{99}\\\phantom{\times}4500000\phantom{999}\\\underline{\phantom{\times}1500000\phantom{9999}}\\\phantom{\times}-624836480\end{array}$$
