It depends on which scale you are converting from and which scale to. But in general you would not go by 10s.
10000
342.5 tens.
5000 ÷ 10 = 500
ok i get this
1,000,000/10 = 100,000 (a hundred thousand).
It goes in 37.5 times or 37 times with a remainder of 5.
1, remainder 3
3 and 1/2 of them.
Watch closely:100,000 / 10 = 10,000
There are 8 10s in 85, with 5 left over.
