870543 divided by 2 
Our goal is to divide 870543 by 2.

On to step 1:
When dividing 8 by 2, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 8 from 8 and we're left with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 2

Advancing to step 2:
7 divided by 2 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 43.0
If we take 6 away from 7, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 2

Let's proceed to step 3:
If we divide 10 by 2, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 435.0
The remainder is 0 after subtracting 10 from 10.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 2

Advancing to step 4:
If we divide 5 by 2, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 4352.0
Subtracting 4 from 5 leaves us with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 2

Let's proceed to step 5:
The number 2 fits into 14 7 times, leaving a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 43527.0
Deduct 14 from 14 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 2

Let's proceed to step 6:
3 divided by 2 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 435271.0
Deduct 2 from 3 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.

Step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 435271.5
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.

Step 8:
2 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 435271.5
If we subtract 0 from 0, we 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.

Let's proceed to step 9:
0 divided by 2 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 435271.5
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 quotient of the division is 435271.5, and the remainder is 0.0.
