Python:素数分解大整数除法总是返回错误的结果

from decimal import Decimal

def prime_factorization(n):
    factors = []
    i = 2
    while i * i <= n:
        if n % i:
            i += 1
        else:
            n //= i
            factors.append(i)
    if n > 1:
        factors.append(n)
    return factors

def divide_large_integer(n, divisor):
    quotient = Decimal(n) / Decimal(divisor)
    return quotient

# 示例用法
number = 12345678901234567890
divisor = 12345

factors = prime_factorization(number)
quotient = divide_large_integer(number, divisor)

print("素数分解结果：", factors)
print("大整数除法结果：", quotient)
