We look at the division of 642868 by 16 
We want to divide 642868 by 16.

Let's proceed to step 1:
The number 16 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 16

Advancing to step 2:
When dividing 64 by 16, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 64 from 64 and we're left with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 16

Step 3:
If we divide 2 by 16, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 16

Step 4:
28 divided by 16 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 401.0
Subtract 16 from 28 to get 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 16

Step 5:
16 can be fit into 126 7 times, resulting in a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 4017.0
Deduct 112 from 126 and we're left with 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 16

Step 6:
When dividing 148 by 16, we get 9 with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 40179.0
The remainder is 4 after subtracting 144 from 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
The number 16 fits into 40 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 40179.2
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.

Step 8:
16 goes into 80 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 40179.25
If we subtract 80 from 80, 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.

On to step 9:
When dividing 0 by 16, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40179.25
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.

Moving on to step 10:
0 divided by 16 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 40179.25
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.

The final outcome is 40179.25, with a leftover of 0.0.
