We're dividing 430886 by 2 
Let's see how many times 2 fits into 430886.

Advancing to step 1:
If we divide 4 by 2, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 0 after subtracting 4 from 4.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 2

Advancing to step 2:
3 divided by 2 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtracting 2 from 3 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 2

On to step 3:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 215.0
Subtracting 10 from 10 leaves us with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 2

On to step 4:
The number 2 fits into 8 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 2154.0
The remainder is 0 after subtracting 8 from 8.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 2

Let's proceed to step 5:
2 goes into 8 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 21544.0
Deduct 8 from 8 and we're left with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 2

Let's proceed to step 6:
6 divided by 2 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 215443.0
Subtracting 6 from 6 leaves us 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: 215443.0
Subtracting 0 from 0 leaves us 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 8:
2 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 215443.0
Subtracting 0 from 0 leaves us 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 215443.0, and the remainder is 0.0.
