781451 divided by 2 
Let's see how many times 2 fits into 781451.

Step 1:
7 divided by 2 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 1 after subtracting 6 from 7.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 2

Let's proceed to step 2:
2 goes into 18 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
The remainder is 0 after subtracting 18 from 18.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

Let's proceed to step 3:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 390.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 2

Step 4:
2 can be fit into 14 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 3907.0
If we subtract 14 from 14, we get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

Moving on to step 5:
When dividing 5 by 2, we get 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 39072.0
The remainder is 1 after subtracting 4 from 5.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Let's proceed to step 6:
When dividing 11 by 2, we get 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 390725.0
If we take 10 away from 11, we end up 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.

Step 7:
10 divided by 2 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 390725.5
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.

Moving on to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 390725.5
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.

Moving on 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: 390725.5
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.

The quotient of the division is 390725.5, and the remainder is 0.0.
