What is your problem/question?
Can you be more explicit?

Mathematical relation between % ( remainder ) and // ( integer quotient ) is:

if a == x / y
then a == ( y * ( x // y ) ) + ( x % y )

... or, by a Python demonstration way:
"""

x=42
y=8

a = x // y
print(a)

r = x % y
print(r)

b = ( y * a ) + r
print(b)

print( ( y * ( x // y ) ) + ( x % y ) )
