We look at the division of 43386 by 2 
We want to figure out the number of times 43386 can be divided by 2.

Advancing to step 1:
When dividing 4 by 2, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
If we take 4 away from 4, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 2

Advancing to step 2:
2 goes into 3 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 1 after subtracting 2 from 3.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 2

Let's proceed to step 3:
13 divided by 2 is 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 216.0
The remainder is 1 after subtracting 12 from 13.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

On to step 4:
2 goes into 18 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 2169.0
If we take 18 away from 18, we end up with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

Let's proceed to step 5:
2 can be fit into 6 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 21693.0
Deduct 6 from 6 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 6:
0 divided by 2 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 21693.0
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.

Let's proceed to step 7:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21693.0
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 final outcome is 21693.0, with a leftover of 0.0.
