    As a domain expert in mathematics, I can provide an insightful explanation about the concept of the least 8-digit number. Let's delve into the topic by understanding the nature of numerical sequences and the concept of successor numbers.
    The least 8-digit number is a term that refers to the smallest number that has exactly eight digits. To determine this, we must first understand the structure of numbers in the decimal system. In the decimal system, each place value represents a power of 10, with the rightmost digit representing the ones place, and each subsequent digit to the left representing the tens, hundreds, thousands, and so on, up to the billions place for a total of nine places.

    When we talk about the largest 7-digit number, we are referring to the number that has the highest value possible with exactly seven digits. In the decimal system, this number is 9,999,999. It is the largest because each digit is at its maximum value of 9, which is the highest single digit number in the decimal system.

    The successor of a number is the next number in the sequence. To find the successor of 9,999,999, we simply add 1 to it. This is because in the decimal system, when a digit reaches the value of 9, the next increment causes a carry-over to the next place value, effectively resetting the current place value to 0 and incrementing the next place value by 1.

    So, when we add 1 to 9,999,999, we get:
    \[ 9,999,999 + 1 = 10,000,000 \]

    This calculation shows that the successor of the largest 7-digit number is the smallest 8-digit number. Therefore, 10,000,000 is the least 8-digit number. It is the first number in the sequence of 8-digit numbers and represents the smallest value that can be represented with exactly eight digits in the decimal system.

    In conclusion, the concept of the least 8-digit number is straightforward once we understand the structure of the decimal system and how numbers progress from one digit to the next. The least 8-digit number is simply the next number after the largest 7-digit number, which is 10,000,000.

    Now, let's proceed to the next step as per your instructions.
