We look at the division of 385866 by 2 
Let's see how many times 2 fits into 385866.

On to step 1:
2 goes into 3 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 2 from 3 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 2

Step 2:
2 can be fit into 18 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 19.0
If we subtract 18 from 18, we get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 2

Going ahead to step 3:
If we divide 5 by 2, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 192.0
Deduct 4 from 5 and we're left with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

Advancing to step 4:
2 goes into 18 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 1929.0
If we subtract 18 from 18, we get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 2

Moving on to step 5:
2 goes into 6 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 19293.0
Subtracting 6 from 6 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

Step 6:
If we divide 6 by 2, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 192933.0
Subtract 6 from 6 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.

Moving on to step 7:
If we divide 0 by 2, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 192933.0
Deduct 0 from 0 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 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 192933.0
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 final result is 192933.0 with a remainder of 0.0.
