逐步解答

1. 建立长除法

$\frac{12346}{1000000}$

$\frac{12346}{1000000} = 12346 \div 1000000$ .

$\frac{12346}{1000000}$

$\frac{12346}{1000000} = 12346 \div 1000000$ .

$\frac{12346}{1000000}$

$\frac{12346}{1000000} = 12346 \div 1000000$ .

$12346 \div 1000000$

$\frac{12346}{1000000} = 12346 \div 1000000$ .

$12346 \div 1000000$

$\frac{12346}{1000000} = 12346 \div 1000000$ .

2. 识别循环周期

$\frac{12346}{1000000}$

$12346 \to 123460 \to 234600 \to 346000 \to 460000 \to 600000$ , .

$\frac{12346}{1000000}$

$\frac{123460}{1000000} = d i g i t 0, r e m a \in d e r 123460$

$12346 \to 123460 \to 234600 \to 346000 \to 460000 \to 600000$ , .

$123460$

$\frac{1234600}{1000000} = d i g i t 1, r e m a \in d e r 234600$

$12346 \to 123460 \to 234600 \to 346000 \to 460000 \to 600000$ , .

$234600$

$\frac{2346000}{1000000} = d i g i t 2, r e m a \in d e r 346000$

$12346 \to 123460 \to 234600 \to 346000 \to 460000 \to 600000$ , .

$346000$

$\frac{3460000}{1000000} = d i g i t 3, r e m a \in d e r 460000$

$12346 \to 123460 \to 234600 \to 346000 \to 460000 \to 600000$ , .

$460000$

$\frac{4600000}{1000000} = d i g i t 4, r e m a \in d e r 600000$

$12346 \to 123460 \to 234600 \to 346000 \to 460000 \to 600000$ , .

$600000$

$\frac{6000000}{1000000} = d i g i t 6, r e m a \in d e r 0$

$12346 \to 123460 \to 234600 \to 346000 \to 460000 \to 600000$ , .

$0$

$12346 \to 123460 \to 234600 \to 346000 \to 460000 \to 600000$ , .

$0.012346$

$12346 \to 123460 \to 234600 \to 346000 \to 460000 \to 600000$ , .

3. 写出循环小数

$\frac{12346}{1000000} = 0.012346$

$0.012346$

$12, 346 () = 0.012346$ .

$0.012346$

$12, 346 () = 0.012346$ .

$0.012346$

$12, 346 () = 0.012346$ .
