872405 divided by 2 
Let's see how many times 2 fits into 872405.

Going ahead to step 1:
2 goes into 8 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 8 from 8 leaves us with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 2

Advancing to step 2:
2 goes into 7 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
The remainder is 1 after subtracting 6 from 7.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

Going ahead to step 3:
If we divide 12 by 2, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 436.0
Subtracting 12 from 12 leaves us with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 2

On to step 4:
If we divide 4 by 2, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 4362.0
The remainder is 0 after subtracting 4 from 4.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 2

On to step 5:
If we divide 0 by 2, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 43620.0
If we subtract 0 from 0, we get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 2

Advancing to step 6:
The number 2 fits into 5 2 times, leaving a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 436202.0
Deduct 4 from 5 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 436202.5
If we take 10 away from 10, we end up 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.

Moving on to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 436202.5
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 9:
If we divide 0 by 2, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 436202.5
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.

The final outcome is 436202.5, with a leftover of 0.0.
