We divide 878693 by 2
We want to figure out the number of times 878693 can be divided by 2.

On to step 1:
2 goes into 8 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 8 from 8 to get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 2

Let's proceed to step 2:
2 can be fit into 7 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtracting 6 from 7 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 2

Step 3:
The number 2 fits into 18 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 439.0
Deduct 18 from 18 and we're left with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 2

On to step 4:
If we divide 6 by 2, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 4393.0
Deduct 6 from 6 and we're left with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 2

Step 5:
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: 43934.0
Deduct 8 from 9 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 2

Moving on to step 6:
2 can be fit into 13 6 times, resulting in a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 439346.0
If we subtract 12 from 13, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
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: 439346.5
Subtract 10 from 10 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.

Let's proceed to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 439346.5
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.

Advancing to step 9:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 439346.5
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 result is 439346.5 with a remainder of 0.0.
