259940 ÷ 16 
Let's see how many times 16 fits into 259940.

Let's proceed to step 1:
2 divided by 16 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 16

On to step 2:
If we divide 25 by 16, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 16 from 25 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 16

Going ahead to step 3:
The number 16 fits into 99 6 times, leaving a remainder of 3.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 96 from 99, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 16

Moving on to step 4:
16 goes into 39 2 times with a remainder of 7.
The next digit of our result is 2. 
Result so far: 162.0
Subtracting 32 from 39 leaves us with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 16

Step 5:
16 goes into 74 4 times with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 1624.0
Deduct 64 from 74 and we're left with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 16

Moving on to step 6:
If we divide 100 by 16, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 16246.0
If we take 96 away from 100, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
The number 16 fits into 40 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 16246.2
If we subtract 32 from 40, we 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 8:
16 goes into 80 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 16246.25
If we take 80 away from 80, we end up 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 9:
0 divided by 16 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 16246.25
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.

On to step 10:
If we divide 0 by 16, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16246.25
If we take 0 away from 0, we end up 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.

The final outcome is 16246.25, with a leftover of 0.0.
