Thread: Divide two large numbers

I am trying to find a logic which can give me one digit (first digit on the left of decimal dot) after division.

The ultimate goal is given below,

number A / number B mod 2 =?

The concern is the two numbers (A & B) are two large. Any trick can help.

Example: 913695089923267549815145223638290430 / 70369745177664

I am a database developer (IT Professional) and finding it difficult to do. I am not sure I chose correct forum (type) or not?

Have you tried repeated subtraction until the answer is less than B?

count = 1
temp(count) = A - B
do
count = count + 1
temp(count) = temp(count-1) - B
while (temp(count)>B)

ans = temp(count-1)/B


or sumit like that
