43479 divided by 2 
We're looking to find how many times 2 goes into 43479.

Step 1:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 0 after subtracting 4 from 4.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 2

On to step 2:
If we divide 3 by 2, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 2 from 3, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 2

Going ahead to step 3:
2 goes into 14 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 217.0
Deduct 14 from 14 and we're left with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 2

Advancing 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: 2173.0
Subtract 6 from 7 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

On to step 5:
When dividing 19 by 2, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 21739.0
Subtract 18 from 19 to 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.

Going ahead to step 6:
When dividing 10 by 2, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 21739.5
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.

Moving on to step 7:
When dividing 0 by 2, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21739.5
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.

Let's proceed to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21739.5
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 final result is 21739.5 with a remainder of 0.0.
