We look at the division of 166805 by 2 
We want to divide 166805 by 2.

Going ahead to step 1:
2 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 2

Advancing to step 2:
2 can be fit into 16 8 times, resulting in a remainder of 0.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 16 from 16 leaves us with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 2

Moving on to step 3:
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: 83.0
Subtracting 6 from 6 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 2

On to step 4:
If we divide 8 by 2, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 834.0
If we take 8 away from 8, we end up with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 2

Going ahead to step 5:
2 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8340.0
Subtracting 0 from 0 leaves us with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 2

Advancing to step 6:
The number 2 fits into 5 2 times, leaving a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 83402.0
Subtract 4 from 5 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.

On to step 7:
2 goes into 10 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 83402.5
If we subtract 10 from 10, 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.

On to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 83402.5
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.

Going ahead to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 83402.5
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.

Our division results in 83402.5 with a remaining 0.0.
