Step-by-step explanation:
To convert any decimal number to binary you need to make a succession of divisions by 2, in the image I provide, you can see how the process was done, every time you divide your number by 2 you'll have a remainder, being this 0 or 1, this will become your binary number. It's important to notice that using this method you'll divide from right to left, but you'll take your remainders in the opposite direction (right to left) to form your binary number.
Hope you find this information useful! Good luck!
