Is there any fix number on how many elements should the splitted array have?

Give this a go.

a!localVariables(
  local!singleArray: {"One","Two","Three","Four","Five","Six","Seven","Eight","Nine","Ten"},
  local!lengthOfSingleArray: if(
    a!isNullOrEmpty(local!singleArray),
    0,
    length(local!singleArray)
  ),
  if(
    local!lengthOfSingleArray = 0,
    {},
    a!localVariables(
      local!desiredLengthOfEachSplitArray: 4,
      local!numberOfFullLengthBlocks: rounddown(
        local!lengthOfSingleArray/local!desiredLengthOfEachSplitArray,
        0
      ),
      local!remainder: mod(
        local!lengthOfSingleArray,
        local!desiredLengthOfEachSplitArray
      ),
      local!numberOfArraysInOutput: sum(
        local!numberOfFullLengthBlocks,
        local!remainder <> 0
      ),
      a!forEach(
        items: 1 + enumerate(local!numberOfArraysInOutput),
        expression: index(
          local!singleArray,
          sum(
            product(fv!index - 1, local!desiredLengthOfEachSplitArray),
            1
          ) + enumerate(
            if(
              and(
