516840 divided by 16 
Our goal is to divide 516840 by 16.

Let's proceed to step 1:
If we divide 5 by 16, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 16

Step 2:
16 can be fit into 51 3 times, resulting in a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 48 from 51, we get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 16

Advancing to step 3:
16 goes into 36 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Deduct 32 from 36 and we're left with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 16

Step 4:
48 divided by 16 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 323.0
If we take 48 away from 48, we end up with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 16

On to step 5:
16 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 3230.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 16

Advancing to step 6:
The number 16 fits into 40 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 32302.0
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.

On to step 7:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 32302.5
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.

Let's proceed to step 8:
If we divide 0 by 16, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 32302.5
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.

Going ahead to step 9:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 32302.5
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.

Our division results in 32302.5 with a remaining 0.0.
