See below how to convert 1 100 001 520(10), the unsigned base 10 decimal system number to base 2 binary equivalent

What are the required steps to convert base 10 decimal system
number 1 100 001 520 to base 2 unsigned binary equivalent?

  • A number written in base ten, or a decimal system number, is a number written using the digits 0 through 9. A number written in base two, or a binary system number, is a number written using only the digits 0 and 1.

1. Divide the number repeatedly by 2:

Keep track of each remainder.

Stop when you get a quotient that is equal to zero.


  • division = quotient + remainder;
  • 1 100 001 520 ÷ 2 = 550 000 760 + 0;
  • 550 000 760 ÷ 2 = 275 000 380 + 0;
  • 275 000 380 ÷ 2 = 137 500 190 + 0;
  • 137 500 190 ÷ 2 = 68 750 095 + 0;
  • 68 750 095 ÷ 2 = 34 375 047 + 1;
  • 34 375 047 ÷ 2 = 17 187 523 + 1;
  • 17 187 523 ÷ 2 = 8 593 761 + 1;
  • 8 593 761 ÷ 2 = 4 296 880 + 1;
  • 4 296 880 ÷ 2 = 2 148 440 + 0;
  • 2 148 440 ÷ 2 = 1 074 220 + 0;
  • 1 074 220 ÷ 2 = 537 110 + 0;
  • 537 110 ÷ 2 = 268 555 + 0;
  • 268 555 ÷ 2 = 134 277 + 1;
  • 134 277 ÷ 2 = 67 138 + 1;
  • 67 138 ÷ 2 = 33 569 + 0;
  • 33 569 ÷ 2 = 16 784 + 1;
  • 16 784 ÷ 2 = 8 392 + 0;
  • 8 392 ÷ 2 = 4 196 + 0;
  • 4 196 ÷ 2 = 2 098 + 0;
  • 2 098 ÷ 2 = 1 049 + 0;
  • 1 049 ÷ 2 = 524 + 1;
  • 524 ÷ 2 = 262 + 0;
  • 262 ÷ 2 = 131 + 0;
  • 131 ÷ 2 = 65 + 1;
  • 65 ÷ 2 = 32 + 1;
  • 32 ÷ 2 = 16 + 0;
  • 16 ÷ 2 = 8 + 0;
  • 8 ÷ 2 = 4 + 0;
  • 4 ÷ 2 = 2 + 0;
  • 2 ÷ 2 = 1 + 0;
  • 1 ÷ 2 = 0 + 1;

2. Construct the base 2 representation of the positive number:

Take all the remainders starting from the bottom of the list constructed above.

1 100 001 520(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 100 001 520 (base 10) = 100 0001 1001 0000 1011 0000 1111 0000 (base 2)

Spaces were used to group digits: for binary, by 4, for decimal, by 3.

How to convert unsigned integer numbers (positive) from decimal system (base 10) to binary = simply convert from base 10 to base 2

Follow the steps below to convert a base ten unsigned integer number to base two:

  • 1. Divide repeatedly by 2 the positive integer number that has to be converted to binary, keeping track of each remainder, until we get a QUOTIENT that is equal to ZERO.
  • 2. Construct the base 2 representation of the positive integer number, by taking all the remainders starting from the bottom of the list constructed above. Thus, the last remainder of the divisions becomes the first symbol (the leftmost) of the base two number, while the first remainder becomes the last symbol (the rightmost).

Example: convert the positive integer number 55 from decimal system (base ten) to binary code (base two):

  • 1. Divide repeatedly 55 by 2, keeping track of each remainder, until we get a quotient that is equal to zero:
    • division = quotient + remainder;
    • 55 ÷ 2 = 27 + 1;
    • 27 ÷ 2 = 13 + 1;
    • 13 ÷ 2 = 6 + 1;
    • 6 ÷ 2 = 3 + 0;
    • 3 ÷ 2 = 1 + 1;
    • 1 ÷ 2 = 0 + 1;
  • 2. Construct the base 2 representation of the positive integer number, by taking all the remainders starting from the bottom of the list constructed above:
  • 55(10) = 11 0111(2)
  • Number 5510, positive integer (no sign), converted from decimal system (base 10) to unsigned binary (base 2) = 11 0111(2)
