**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** <!-- A clear and concise description of what the problem is. Ex. I'm always frustrated when [...] (This section helps Arrow developers understand the context and *why* for this feature, in addition to the *what*) --> i256 division is currently implemented using long division, this is simple but its time complexity is linear with respect to the number of digits in the output quotient. As a result it degrades poorly when dividing large numbers by smaller numbers. **Describe the solution you'd like** <!-- A clear and concise description of what you want to happen. --> There are more sophisticated algorithms for multi-digit division, most famously Knuth Algorithm D. **Describe alternatives you've considered** <!-- A clear and concise description of any alternative solutions or features you've considered. --> **Additional context** <!-- Add any other context or screenshots about the feature request here. --> -- This is an automated message from the Apache Git Service.
