Even though I don't own the exact same model phone as you, I'm pretty sure the rooting process is similar for all Samsung Galaxy S3 phones. When I first rooted my phone a few years ago, I found that there were several articles on the internet that explained the process step-by-step. Here's one that I found for your model phone: https://wiki.cyanogenmod.org/w/Install_CM_for_i9300

The article is for the Samsung Galaxy i9300. (You posted a different model number, but I believe you mistakenly took the "i" for a "1".) After you flash custom recovery software onto your phone, you will be able to install ZIP packages and different ROMs. Make sure you perform a backup of everything on your phone (including the stock ROM) before you start messing with it. Good luck!

"The easiest way for the S3 I9300 (international Version) and the S3 I9305 (international Version LTE) is to use krazyroot.
You can find the guide here:
KrazyRoot.com - Learn How To Root Galaxy S3 and Install Custom ROMs
To sum it up, you just have to install the apk and run it.
This installs SuperUser and the su binary. That's it, you are rooted!
Another way is using the chainfire root method.

You'll need odin and the rootkernel(download button at the very bottom of the page).
Now, make sure your phone is charged. Kill all Kies processes in the taskmanager.
Copy pasta from the xda thread:
Unzip the attached Odin3-vX.X.zip file
Download and unzip the CF-Root-SGS3-vX.X.zip file (see posts below this one)
If you end up with a recovery.img and cache.img file, you've extracted twice. You need to end up with a .tar file - don't extract that one
(USB) Disconnect your phone from your computer
Start Odin3-vX.X.exe
Click the PDA button, and select CF-Root-SGS3-vX.X.tar
Put your phone in download mode (turn off phone, then hold volume-down + home + power to boot - if it asks you to press a button to continue, press the listed button, or run adb reboot download command)
(USB) Connect the phone to your computer
Make sure Repartition is NOT checked
Click the Start button
Wait for Android to boot
Done!"
