Now that you have an operation that will lower the value of input each time the loop runs, you don't have to worry about the loop running forever.

Update the last line of your while loop and assign quotient to input.

--hints--

You should assign quotient to input at the end of your while loop.

assert.match(code, /while\s*\(\s*input\s*>\s*0\s*\)\s*\{[\s\S]*input\s*=\s*quotient\s*;?\s*\}/);
