We look at the division of 169781 by 2 
We want to divide 169781 by 2.

On to step 1:
2 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 2

On to step 2:
If we divide 16 by 2, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 16 from 16 and we're left with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 2

Moving on to step 3:
If we divide 9 by 2, we get 4 and a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Subtracting 8 from 9 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 2

Let's proceed to step 4:
17 divided by 2 is 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 848.0
If we subtract 16 from 17, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

Going ahead to step 5:
When dividing 18 by 2, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 8489.0
Subtract 18 from 18 to get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

Let's proceed to step 6:
1 divided by 2 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 84890.0
If we subtract 0 from 1, we 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.

Let's proceed to step 7:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 84890.5
Subtracting 10 from 10 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.

Going ahead to step 8:
2 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 84890.5
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.

Step 9:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 84890.5
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.

After the division, we end up with 84890.5 and a remainder of 0.0.
