function [whatsLeft, divisionCount] = divideBySeven (number)
% Enter the code for your function here.   
while number <1
    number = number / 7
    divisionCount = divisionCount + 1    
end    
whatsLeft = number

In the above you are using the variable divisonCountinside the loop and you have not defined it. You have to define it.

function [whatsLeft, divisionCount] = divideBySeven (number)
% Enter the code for your function here.   
divisionCount = 0;
while number <1
    number = number / 7
    divisionCount = divisionCount + 1    
end    
whatsLeft = number
