We're dividing 870660 by 2 
Our goal is to divide 870660 by 2.

Going ahead 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
If we take 8 away from 8, we end up with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 2

On to step 2:
When dividing 7 by 2, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtract 6 from 7 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 2

Let's proceed to step 3:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 435.0
If we subtract 10 from 10, we get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 2

Going ahead to step 4:
2 goes into 6 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 4353.0
If we subtract 6 from 6, we get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 2

Step 5:
2 goes into 6 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 43533.0
Subtracting 6 from 6 leaves us with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 2

Step 6:
If we divide 0 by 2, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 435330.0
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.

Moving on to step 7:
If we divide 0 by 2, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 435330.0
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.

Step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 435330.0
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.

In conclusion, the division gives 435330.0 with a balance of 0.0.
