    Once you've arrived at your solution, then if you have 50 minutes to
    spare, you may enjoy the Mathologer video describing Ramanujan's partial fraction solution to the original problem.

    I don't have 50 minutes right now, but I think the "partial fractions"
    here are what are usually called the "convergents" of a continued
    fraction.

    Yes, having looked at the link below, that looks to be what I should
    have said. Thanks for the correction.

    NRICH provides some information if continued fractions are new to you.
