We divide 785481 by 2
Let's see how many times 2 fits into 785481.

On to step 1:
2 goes into 7 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 1 after subtracting 6 from 7.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

Going ahead to step 2:
The number 2 fits into 18 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we subtract 18 from 18, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 2

Step 3:
The number 2 fits into 5 2 times, leaving a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 392.0
Subtract 4 from 5 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 2

Moving on to step 4:
If we divide 14 by 2, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 3927.0
Subtracting 14 from 14 leaves us with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 2

On to step 5:
8 divided by 2 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 39274.0
If we subtract 8 from 8, we get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

Let's proceed to step 6:
1 divided by 2 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 392740.0
Deduct 0 from 1 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.

Going ahead to step 7:
10 divided by 2 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 392740.5
The remainder is 0 after subtracting 10 from 10.
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 8:
2 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 392740.5
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 9:
If we divide 0 by 2, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 392740.5
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.

The final outcome is 392740.5, with a leftover of 0.0.
