The algorithm to be used is that of long division method. You first divide dividents highest place value (greater than divisor) by divisor, ie, 6 by 4 which gives you 1 and 2 is left as remainder. Now you have 248 left as dividend. Next following the same algorithm, you do 24 divided by 4 = 6 and 0 is left as remainder. Now the dividend is 8. 8 divided by 4 = 2 and remainder is 0.
So your final answer is 162.
