period
There are 3 identical digits in the units period. If the number started with 23 then 2 + 3 = 5 and 20 - 5 = 15 which is divisible by three. If the number started with 24 then 2 + 4 = 6 and 20 - 6 = 14 is not divisible by 3. So the number is 23,000,555.
3. Split the number into blocks of 3 digits from the right hand end (34 816). Then in each block, the digits are H-T-U = Hundreds-Tens-Units. From the right hand end the blocks are "none", "Thousands", "Millions", ... So the ten thousands place is the tens digit (second from right hand end of the block) of the thousands block (second from the right hand end): thousands.......none .... HTU............ HTU ........34............. 816 Ten-thousands digit = 3.
I could give you the answer, but it will be more fun if you try to figure it out yourself. Here are the basic rules: To the right of "millions", there should be 6 digits. In other words, write the "13" and make sure there are 6 digits to the right of these digits. To the right of the thousands, in this case, the digits "18", there should be 3 digits. Use zeroes to fill out.

25 digit numbers would be septillions.
There are 3 identical digits in the units period. If the number started with 23 then 2 + 3 = 5 and 20 - 5 = 15 which is divisible by three. If the number started with 24 then 2 + 4 = 6 and 20 - 6 = 14 is not divisible by 3. So the number is 23,000,555.
Commas are used to separate large numbers into groups of three digits. Each group is called a period.
200,000. Since the number 200 is in the hundreds, it will be 3 digits long. A number in the thousands has at least 4 digits, and up to 6. The number one thousand is written like this: 1,000. Putting the number 1 in the thousands requires adding 3 zeros to the end of it, so writing the number 200 in the thousands would require the same strategy. Therefore, you'd get to your answer: 200,000.

That happens ten times in a 12-hour period.
