for this example we will use the equation 85434 divided by 37
Write down the problem as usual. Leave some space on the left and right.
Write down '1x=' to the left of the divisor. Leave two spaces inbetween.
Write down '2x=' right below the '1x='.
Double the divisor and write it underneath - keeping the ones column lined up. Doubling 37 gets you 74.
Write down '4x=' right below the '2x='. (It would be easy to write three X instead, but remember you are doubling. An alternate name for this method is 1-2-4-8 Divsion in order to pound home this point.)
Double the divisor again and write it underneath - keeping the ones column lined up. Doubling 74 gets you 148.
Write down '8x=' right below the '4x='.
Double the divisor again and write it underneath - keeping the ones column lined up. Doubling 148 gets you 296.
Choose the best number from the divisor column to write under the dividend. You can slide the number over one if you need to.
Fill in to the right with zeros. Say to yourself, "ZERO, ZERO, ZERO."
Write the multiplier you used (1, 2, 4, or 8) on the right, followed by the same number of zeros you just wrote. Say to yourself, "ZERO, ZERO, ZERO."
Subtract
Choose the best number from the divisor column to write under what's left of the dividend. You can slide the number over one if you need to.

Write the multiplier you used (1, 2, 4, or 8) on the right. No need to write any zeros afterwards.

Write the multiplier you used (1, 2, 4, or 8) on the right. No need to write any zeros afterwards.
Subtract. ==> Notice that the amount left over is less than the divisor - so you're done.
Add up your answer on the right. The remainder is 1.
Write the answer on the top.
hope this gives a little understanding :) have a great day/night!
