What fundamental challenge persisted in mechanical computation, illustrated by the Stepped Reckoner's operation?

Answer

Calculations involving large numbers or many digits were slow due to reliance on iteration.

Because multiplication and division relied on repeated addition or subtraction, calculations involving many digits became very slow, requiring numerous manual or crank-driven steps.
