We're dividing 256858 by 16 
We're looking to find how many times 16 goes into 256858.

Step 1:
The number 16 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 16

Going ahead to step 2:
16 goes into 25 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 16 from 25 and we're left with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 16

Advancing to step 3:
16 can be fit into 96 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 0 after subtracting 96 from 96.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 16

Advancing to step 4:
If we divide 8 by 16, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 160.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 16

Moving on to step 5:
When dividing 85 by 16, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1605.0
The remainder is 5 after subtracting 80 from 85.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 16

Let's proceed to step 6:
The number 16 fits into 58 3 times, leaving a remainder of 10.
The next digit of our result is 3. 
Result so far: 16053.0
Subtracting 48 from 58 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
If we divide 100 by 16, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 16053.6
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
When dividing 40 by 16, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 16053.62
Subtract 32 from 40 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 16053.625
The remainder is 0 after subtracting 80 from 80.
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 10:
0 divided by 16 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 16053.625
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.

Going ahead to step 11:
0 divided by 16 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16053.625
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.

The final result is 16053.625 with a remainder of 0.0.
