We're dividing 390846 by 2 
We want to divide 390846 by 2.

On to step 1:
When dividing 3 by 2, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 2 from 3, we get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 2

Step 2:
19 divided by 2 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 18 from 19 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

Let's proceed to step 3:
If we divide 10 by 2, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 195.0
Deduct 10 from 10 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 2

Advancing to step 4:
When dividing 8 by 2, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 1954.0
Subtract 8 from 8 to get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 2

Step 5:
When dividing 4 by 2, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 19542.0
Deduct 4 from 4 and we're left with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

Step 6:
When dividing 6 by 2, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 195423.0
Subtract 6 from 6 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.

Advancing to step 7:
When dividing 0 by 2, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 195423.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to 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: 195423.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 195423.0 with a remaining 0.0.
