OP_DIV ​
INFO
Opcode number: 150
Byte representation: 0x96
Short description: Fail the script unconditionally, does not even need to be executed.
OP_DIV is a disabled opcode in the Bitcoin scripting system.
Historical Context ​
OP_DIV was initially intended for division operations, specifically to divide the second-to-top stack item by the top stack item.
Due to concerns about potential vulnerabilities and the desire to simplify the scripting language, OP_DIV (along with several other opcodes) was disabled early in bitcoin's development.
Operation ​
Because OP_DIV is disabled, any script that contains it will render the transaction invalid regardless of context.
