Taking three errors in a hundred divisors as eight means that the number of errors is 500 more than the original number, resulting in an extra quotient of 2 1, leaving 17, and there is no remainder in the original number. If you read this sentence clearly, you can get (extra dividend part ÷ divisor = extra quotient part ....................................................................... 500÷ divider = 2 1... 17). You can calculate that the divisor is 23. The correct quotient is 383-2 1=362. If there is no remainder, you can calculate the dividend as 362×23=8326.
