Problem:
 div(x,y) -> div2(x,y,0())
 div2(x,y,i) -> if1(le(y,0()),le(y,x),x,y,plus(i,0()),inc(i))
 if1(true(),b,x,y,i,j) -> divZeroError()
 if1(false(),b,x,y,i,j) -> if2(b,x,y,i,j)
 if2(true(),x,y,i,j) -> div2(minus(x,y),y,j)
 if2(false(),x,y,i,j) -> i
 inc(0()) -> 0()
 inc(s(i)) -> s(inc(i))
 le(s(x),0()) -> false()
 le(0(),y) -> true()
 le(s(x),s(y)) -> le(x,y)
 minus(x,0()) -> x
 minus(0(),y) -> 0()
 minus(s(x),s(y)) -> minus(x,y)
 plus(x,y) -> plusIter(x,y,0())
 plusIter(x,y,z) -> ifPlus(le(x,z),x,y,z)
 ifPlus(true(),x,y,z) -> y
