Incorrect spelling, explanation: as mentioned before, successful has a Latin root word, succedere, which means that the spelling must remain faithful to the original, thus double c in successful (this of course makes spelling sucessful incorrect). If you’re unsure which form is correct, you can remember that the double c in successful can be read as k’s, while the single c can not.

Correct spelling, explanation: successful comes from the base word success with the adjective suffix -ful. The word success itself comes from the Latin word succedere which explains the double c. Currently, thanks to the double C, the word is pronounced as /səkˈsesf(ə)l/ based on this spelling, so it can be a reminder when You’re not sure which form is correct.
