An apparatus and method are provided, the apparatus comprising: storage circuitry to store an input data value; divider circuitry to split the input data value into at least one sub-value in dependence on a number of lanes for a current iteration, each sub-value occupying a lane, and to operate on each sub-value to generate a quotient corresponding to the division of that sub-value by a divisor, wherein the divisor is an odd integer; remainder circuitry to operate on each sub-value to generate a remainder corresponding to the remainder of dividing that sub-value by the divisor; concatenation circuitry to concatenate each quotient to produce a concatenated division value, and to concatenate each remainder to produce a concatenated remainder value, in each subsequent iteration, the input data value being formed from the concatenated remainder value of a preceding iteration; and output circuitry to output, after a plurality of iterations, a result of adding the concatenated division values produced by said plurality of iterations.
