1235678 has how many tens in it? how many hundreds in it? and how many thousands? explain

7 tens, 6 hundreds, and 5 thousands.

My guess:
It has 7 tens because the 7 is in the tenths place.
It has 6 hundreds in it because a 6 is in the hundredths place.
And 5 thousands because a 5 is in the thousandths place.

My second mathematical guess:
123,567.8 tens because 12345678 divided by ten is that.
123456.78 hundredths because ^^^hundreds
12345.678 thousandths because^^^ thousands
Or another explanation for my second guess is each 0 it has in it is another decimal place moved to the left of the digits 12345678.
