This is a poor analogy because I don't think your inability to do long division will cause as much damage as an inability to bring the site back up in an emergency situation.

If a team can't bring the site back up in an emergency situation that's poor planning, not poor debugging.

Planning for mitigation before resolution lets a team address production issues at leisure (because the customer impact is mitigated)

All this knowledge is in your agent - ask it for ideas!
