Description

Store the remainder using the divisor type B, which is wide enough for the decimal scale involved in the operation:

  B remainder = unsignedDividendRescaled % unsignedDivisor;

This keeps the rounding decision based on the full decimal-scale remainder while preserving the original result type for the final quotient.

Added regression coverage for the long-decimal ceil case and moved/refactored related decimal vector function tests so the Spark decimal test target includes the relevant coverage.
