We look at the division of 638002 by 2 
We're looking to find how many times 2 goes into 638002.

Let's proceed to step 1:
6 divided by 2 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 6 away from 6, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 2

Advancing to step 2:
If we divide 3 by 2, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we take 2 away from 3, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 2

On to step 3:
2 goes into 18 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 319.0
The remainder is 0 after subtracting 18 from 18.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 2

Step 4:
0 divided by 2 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3190.0
Subtract 0 from 0 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 2

Advancing to step 5:
When dividing 0 by 2, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 31900.0
If we subtract 0 from 0, we get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 2

Going ahead to step 6:
2 goes into 2 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 319001.0
Subtract 2 from 2 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 319001.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 319001.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 319001.0, and the remainder is 0.0.
