I think you're asking for each of these numbers. I'll get you started -- and you can finish.

57 = 5 tens and 7 ones
63 = 6 tens and 3 ones

I assume you mean find how many tens come close and then how many MORE ones we need to make the complete big number.
To find out how many tens, divide by ten, which is the same as moving the decimal point left one space
57/10 = 5.7
so there are 5 tens plus something more to make 57
How much more? Well 5 tens is fifty, so we need an additional 7 ones to make 57
so 57 has 5 tens and 7 ones.
