Asset Split has resulted in negative NBV

Finance user has requested to split Asset A into Asset A, B, C and D (Total 4 asset) with equal cost.

Before Split --> Original cost of Asset A = 85,000, Accum Depreciation = 36,833.35, NBV = 48,166.65, Remaining life = 35 months

After Split --> Cost of Asset A = 85,000 / 4 = 21,250,  Accum Depreciation(unchange) = 36,833.35, NBV = (-15,583.35), Remaining life = 35 months

Is there any alternative way to split an asset to avoid negative net book value?

Thanks,
