869253 divided by 2 
We want to figure out the number of times 869253 can be divided by 2.

Advancing to step 1:
The number 2 fits into 8 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 0 after subtracting 8 from 8.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 2

Going ahead to step 2:
6 divided by 2 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we subtract 6 from 6, we get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 2

Let's proceed to step 3:
If we divide 9 by 2, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 434.0
If we take 8 away from 9, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 2

Moving on to step 4:
When dividing 12 by 2, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 4346.0
Deduct 12 from 12 and we're left with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 2

Step 5:
5 divided by 2 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 43462.0
Deduct 4 from 5 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 2

Advancing to step 6:
2 goes into 13 6 times with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 434626.0
The remainder is 1 after subtracting 12 from 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 434626.5
The remainder is 0 after subtracting 10 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
2 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 434626.5
Deduct 0 from 0 and we're left 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.

Going ahead to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 434626.5
Subtract 0 from 0 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.

After the division, we end up with 434626.5 and a remainder of 0.0.
