"Goes into" is commonly used, although maybe somewhat imprecise. Your
interpretation of "how many groups of" number1 "are contained in" number2, is
much better. Now at least you could use the simple concept of division, which
is repeated subtraction.

Some children drift away from detailed attention to place value, so when they
may try to learn the division algorithm of long division, they may need careful
detailed, and guided help. Not clear, is whether this is about some children,
or about few children.
