670878 divided by 2 
We're looking to find how many times 2 goes into 670878.

Step 1:
If we divide 6 by 2, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 6 away from 6, we end up with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 2

Advancing to step 2:
The number 2 fits into 7 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 33.0
If we subtract 6 from 7, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 2

On to step 3:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 335.0
The remainder is 0 after subtracting 10 from 10.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 2

Going ahead to step 4:
If we divide 8 by 2, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 3354.0
If we take 8 away from 8, we end up with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 2

On to step 5:
When dividing 7 by 2, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 33543.0
The remainder is 1 after subtracting 6 from 7.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 2

Step 6:
2 goes into 18 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 335439.0
Subtract 18 from 18 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:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 335439.0
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.

Moving on to step 8:
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: 335439.0
If we take 0 away from 0, 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.

In conclusion, the division gives 335439.0 with a balance of 0.0.
