Second grade and you’re doing that? Either you’re in an advanced math class or the curriculum is too advanced, because you usually learn division in 3rd grade.
Anyways, you can try multiplying 13 by a number (like 1, 2, 3, etc) until you get the number closest to 54 and is below 54. Then, you put the other factor (1, 2, 3, etc) on top of the “4”, subtract whatever number you got (the product) from for example 13 x 3, from 52, and that’s your remainder.
