We're dividing 430779 by 2 
We want to figure out the number of times 430779 can be divided by 2.

Let's proceed to step 1:
If we divide 4 by 2, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 4 from 4 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 2

Advancing to step 2:
The number 2 fits into 3 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 2 from 3 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 2

On to step 3:
2 can be fit into 10 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 215.0
If we subtract 10 from 10, we get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 2

Moving on to step 4:
7 divided by 2 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 2153.0
If we subtract 6 from 7, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 2

Going ahead to step 5:
17 divided by 2 is 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 21538.0
Subtracting 16 from 17 leaves us with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 2

Let's proceed to step 6:
If we divide 19 by 2, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 215389.0
If we subtract 18 from 19, 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.

Step 7:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 215389.5
If we take 10 away from 10, 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.

Going ahead to step 8:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 215389.5
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.

Advancing to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 215389.5
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 215389.5, and the remainder is 0.0.
