A set of magic numbers: 142857

What is the magic of the six-digit 142857 seemingly ordinary?
Now let's start a game...
We multiply the value of 142857 from 1 to 6 in order, and the following six groups of numbers will appear:
142857 × 1 = 142857
142857 × 2 = 285714
142857 × 3 = 428571
142857 × 4 = 571428
142857 × 5 = 714285
148257 × 6 = 857142
I don't know if you have found out where these six groups of numbers are. A friend who looks at them may have discovered that, right, these six groups of numbers are actually the same 142857,
It's just that the position between numbers has changed...

The number 142857 is multiplied by 999999x7 =. Are you surprised?
Then, divide the number 142857 into two groups of numbers: 142,857.
The sum of the two numbers is 142 + 857 = 999.
Divide 142857 into three groups of numbers:, and 57.
According to the sum of the three numbers, 14 + 28 + 57 = 99
Finally, we multiply 142857 by 142857, and the result is 142857 × 142857 = 20408122449.
Divide 20408122449 into two groups of numbers: 20408 and 122449.
Their sum is: 20408 + 122449 = 142857
The game is over! Do you think these numbers are amazing? I don't know who found it. It's really amazing...
Here are some amazing answers:
142857
It was found in the egyptian pyramid,
It is a group of magic numbers,
It proves that there are 7 days in a week,
It accumulates itself once, and its six numbers rotate in sequence,
They will have a holiday in 7th days, and they will go from 999999 to represent classes,
The larger the number, the more the cycle is over a week. Each number needs to be divided once,
You don't need a computer. You only need to know its separation method, and you can know the answer to continue accumulating,
It also has a magical place to wait for you to explore!
Maybe, it is the password of the universe,
If you find its real secret
Please share with you!
142857 × 1 = 142857 (original number)
142857 × 2 = 285714 (rotation)
142857x3 = 428571 (rotation)
142857 × 4 = 571428 (rotation)
142857x5 = 714285 (rotation)
142857x6 = 857142 (rotation)
142857 × 7 = 999999 (9-shift off)
142857 × 8 = 1142856 (7 parts, that is, divided into the first number 1 and the ending number 6, less than 7 in the series)
142857 × 9 = 1285713 (4 parts)
142857 × 10 = 1428570 (1)
142857 × 11 = 1571427 (8 parts)
142857 × 12 = 1714284 (5 parts)
142857 × 13 = 1857141 (2 parts)
142857 × 14 = 1999998 (9 also needs to become larger)

The singular sum of the numbers above is "9 ". There may be a big secret.
Example of the mysterious pyramid numbers above: 1 + 4 + 2 + 8 + 5 + 7 = 27 = 2 + 7 = 9; you can see that their singular numbers and values are both "9 ". In this way, the number of mysteries above is "9". No blame! (Its dual number and 27 are three to the Power of Three)
