When you need to partition a field using crude tools, there is nothing "easily" done with decimals. Integers are far easier to work with and measure out. This is simply proven by the most basic outdoor experience, which I suppose you don't have. Being able to divide by 2, 3, 4, 5, 6, 8, 9, 10, 11, and 12 is not a "few cases", it's the chief part of the small integers into which stuff often needs to be divided evenly. If you ever went to the market before decimalisation, you would meet many who write prices in fractions. Something would be priced at X pounds/crowns/marks per Y items/weights. Then, the cost of Z units/weights is XZ/Y. When the coins are highly divisible multiples of each other, you have a lot of choices to be able to pay the exact amount and don't have to bother with getting change back. Even better if we price by the dozens (Y = 12) instead of 10s: 12 has twice as many factors than 10. I understand that this all requires a certain numeracy however. Thankfully nowadays we can just buy things using their credit cards on Amazon: makes mindless consumption much easier.
