| Opcode | Instruction | Op/En | 64-Bit Mode | Compat/Leg Mode | Description |
|---|---|---|---|---|---|
| F6 /6 | DIV r/m8 | M | Valid | Valid | Unsigned divide AX by r/m8, with result stored in AL := Quotient, AH := Remainder. |
| REX + F6 /6 | DIV r/m8* | M | Valid | N.E. | Unsigned divide AX by r/m8, with result stored in AL := Quotient, AH := Remainder. |
| F7 /6 | DIV r/m16 | M | Valid | Valid | Unsigned divide DX:AX by r/m16, with result stored in AX := Quotient, DX := Remainder. |
| F7 /6 | DIV r/m32 | M | Valid | Valid | Unsigned divide EDX:EAX by r/m32, with result stored in EAX := Quotient, EDX := Remainder. |
| REX.W + F7 /6 | DIV r/m64 | M | Valid | N.E. | Unsigned divide RDX:RAX by r/m64, with result stored in RAX := Quotient, RDX := Remainder. |
*In 64-bit mode, r/m8 can not be encoded to access the following byte registers if a REX prefix is used: AH, BH, CH, DH.
