### Question:
BaseUInt256Value implements UInt256Value<T> { @Override public T divide(T value) { return divide(value.toUInt256()); } protected  BaseUInt256Value(UInt256 value, Function<UInt256, T> ctor); protected  BaseUInt256Value(long value, Function<UInt256, T> ctor); protected  BaseUInt256Value(BigInteger value, Function<UInt256, T> ctor); @Override T add(T value); T add(UInt256 value); @Override T add(long value); @Override T addMod(T value, UInt256 modulus); T addMod(UInt256 value, UInt256 modulus); @Override T addMod(long value, UInt256 modulus); @Override T addMod(long value, long modulus); @Override T subtract(T value); T subtract(UInt256 value); @Override T subtract(long value); @Override T multiply(T value); T multiply(UInt256 value); @Override T multiply(long value); @Override T multiplyMod(T value, UInt256 modulus); T multiplyMod(UInt256 value, UInt256 modulus); @Override T multiplyMod(long value, UInt256 modulus); @Override T multiplyMod(long value, long modulus); @Override T divide(T value); T divide(UInt256 value); @Override T divide(long value); @Override T pow(UInt256 exponent); @Override T pow(long exponent); @Override T mod(UInt256 modulus); @Override T mod(long modulus); @Override int compareTo(T other); int compareTo(UInt256 other); @Override boolean equals(Object obj); @Override int hashCode(); @Override String toString(); @Override UInt256 toUInt256(); @Override Bytes32 toBytes(); @Override Bytes toMinimalBytes();  }### Answer:
@Test void shouldThrowForDivideByZero() { Throwable exception = assertThrows(ArithmeticException.class, () -> v(5).divide(v(0))); assertEquals("divide by zero", exception.getMessage()); }
@Test void shouldThrowForDivideUInt256ByZero() { Throwable exception = assertThrows(ArithmeticException.class, () -> v(5).divide(UInt256.ZERO)); assertEquals("divide by zero", exception.getMessage()); }
@Test void shouldThrowForDivideLongByZero() { Throwable exception = assertThrows(ArithmeticException.class, () -> v(5).divide(0)); assertEquals("divide by zero", exception.getMessage()); }
@Test void shouldThrowForDivideLongByNegative() { Throwable exception = assertThrows(ArithmeticException.class, () -> v(5).divide(-5)); assertEquals("divide unsigned by negative", exception.getMessage()); }
