We look at the division of 171369 by 2 
We want to divide 171369 by 2.

Moving on to step 1:
1 divided by 2 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 2

Advancing to step 2:
2 can be fit into 17 8 times, resulting in a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 16 from 17, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 2

Going ahead to step 3:
When dividing 11 by 2, we get 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 85.0
If we take 10 away from 11, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 2

On to step 4:
2 can be fit into 13 6 times, resulting in a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 856.0
If we subtract 12 from 13, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 2

Going ahead to step 5:
2 can be fit into 16 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 8568.0
If we take 16 away from 16, we end up with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 2

Step 6:
When dividing 9 by 2, we get 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 85684.0
Subtracting 8 from 9 leaves us with 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 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 85684.5
The remainder is 0 after subtracting 10 from 10.
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:
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: 85684.5
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.

Advancing to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 85684.5
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.

After the division, we end up with 85684.5 and a remainder of 0.0.
