We look at the division of 787124 by 2 
We're looking to find how many times 2 goes into 787124.

Let's proceed to step 1:
If we divide 7 by 2, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 1 after subtracting 6 from 7.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 2

On to step 2:
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: 39.0
Deduct 18 from 18 and we're left with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 2

On to step 3:
7 divided by 2 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 393.0
Subtract 6 from 7 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 2

Moving on to step 4:
If we divide 11 by 2, we get 5 and a remainder of 1.
The next digit of our result is 5. 
Result so far: 3935.0
The remainder is 1 after subtracting 10 from 11.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 2

On to step 5:
12 divided by 2 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 39356.0
If we take 12 away from 12, we end up with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 2

Going ahead to step 6:
When dividing 4 by 2, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 393562.0
Deduct 4 from 4 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.

Going ahead to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 393562.0
If we subtract 0 from 0, we 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 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 393562.0
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.

The quotient of the division is 393562.0, and the remainder is 0.0.
