除法商数定位比较困难,在算盘上不易表达、记住。因此,结合数学原理,我搞了个除法商数定位简易法,与珠算爱好者讨论。一、分清大小数的概念被除数和除数对比大小的方法,不以它们的数值来比较,凡若被除数的位数多于除数的位数时,取除数的位数和被除数的头几位数来比较;反之被除数的位数少于除数的位数时,在被除数的后面加若干个零,直加到与除数的位数相等来比较。凡是被除数大 Division quotient is more difficult to locate, not easy to express on the abacus, remember. Therefore, combined with mathematical principles, I made a simple method of division quotient location, discussed with abacus enthusiasts. First, distinguish between the concept of size Dividend and divisor compared to the size of the method, not to compare their values, where the number of divisor is greater than the number of divisor bits, the number of divisor and the first few digits of the dividend to ; The other hand, the number of divisor less than the median of the divisor, after the dividend plus a few zeros, and added to the same number of divisors to compare. All the big dividend
