R sweep-equivalent with integer division -

is there way use sweep(dataframe) integer division, or equivalent such?

this minimal example of sweep not using integer division - want replace integer division:

sweep(x = mtcars, margin = 2, stats = unlist(mtcars[1,]), fun = '/')

some limitations need stick to:

i need preserve column names of dataframe, done in example above.
i cannot use round, floor, ceil, or similar - needs equivalent of integer division (floor have different effects on negative numbers integer division).
if possible, i'd prefer not store information in additional variables during process.
i'm dealing relatively large dataframe, turn out slow solutions might not option here.

does know way of achieving in r?

pass '%/%' function, integer division. see arithmetic operator docs.

sweep(x = mtcars, margin = 2, stats = unlist(mtcars[1,]), fun = '%/%')
