The Russian peasant multiplication algorithm involves halving one number and doubling the other, discarding any fractions that result from the halving. Both 11 × 1242 (halving 23 and doubling 621) and 46 × 310 (doubling 23 and halving 621) are valid next steps depending on whether you choose to halve the first number and double the second, or vice versa.
