Runtime Complexity TRS:
The TRS R consists of the following rules:

div(0, y) → 0
div(x, y) → quot(x, y, y)
quot(0, s(y), z) → 0
quot(s(x), s(y), z) → quot(x, y, z)
quot(x, 0, s(z)) → s(div(x, s(z)))

Rules:

div(0, z0) → 0
div(z0, z1) → quot(z0, z1, z1)
quot(0, s(z0), z1) → 0
quot(s(z0), s(z1), z2) → quot(z0, z1, z2)
quot(z0, 0, s(z1)) → s(div(z0, s(z1)))
Tuples:

QUOT(s(z0), s(z1), z2) → c3(QUOT(z0, z1, z2))
QUOT(z0, 0, s(z1)) → c4(DIV(z0, s(z1)))
S tuples:

(3) CdtPolyRedPairProof (UPPER BOUND (ADD(O(n^1))) transformation)

Found a reduction pair which oriented the following tuples strictly. Hence they can be removed from S.

QUOT(s(z0), s(z1), z2) → c3(QUOT(z0, z1, z2))
We considered the (Usable) Rules:none
And the Tuples:

DIV(z0, z1) → c1(QUOT(z0, z1, z1))
QUOT(s(z0), s(z1), z2) → c3(QUOT(z0, z1, z2))
QUOT(z0, 0, s(z1)) → c4(DIV(z0, s(z1)))
The order we found is given by the following interpretation:
Polynomial interpretation :

POL(0) = [3]   
POL(DIV(x1, x2)) = [4]x1   
POL(QUOT(x1, x2, x3)) = [4]x1   
POL(c1(x1)) = x1   
POL(c3(x1)) = x1   
POL(c4(x1)) = x1   
POL(s(x1)) = [2] + x1

Tuples:

QUOT(z0, 0, s(z1)) → c4(DIV(z0, s(z1)))

(5) CdtKnowledgeProof (EQUIVALENT transformation)

The following tuples could be moved from S to K by knowledge propagation:

QUOT(z0, 0, s(z1)) → c4(DIV(z0, s(z1)))
DIV(z0, z1) → c1(QUOT(z0, z1, z1))
QUOT(s(z0), s(z1), z2) → c3(QUOT(z0, z1, z2))
Now S is empty
