166854 ÷ 2 
We want to figure out the number of times 166854 can be divided by 2.

Let's proceed to step 1:
When dividing 1 by 2, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 2

On to step 2:
2 can be fit into 16 8 times, resulting in a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 16 from 16 and we're left with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 2

Going ahead to step 3:
If we divide 6 by 2, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
If we take 6 away from 6, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 2

Advancing to step 4:
If we divide 8 by 2, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 834.0
Subtract 8 from 8 to get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 2

Going ahead to step 5:
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: 8342.0
The remainder is 1 after subtracting 4 from 5.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 2

Step 6:
When dividing 14 by 2, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 83427.0
The remainder is 0 after subtracting 14 from 14.
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 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 83427.0
The remainder is 0 after subtracting 0 from 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 8:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 83427.0
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.

After the division, we end up with 83427.0 and a remainder of 0.0.
