Let's divide 686516 by 16
We want to divide 686516 by 16.

Advancing to step 1:
The number 16 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 16

Moving on to step 2:
If we divide 68 by 16, we get 4 and a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 64 away from 68, we end up with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 16

On to step 3:
When dividing 46 by 16, we get 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtracting 32 from 46 leaves us with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 16

Let's proceed to step 4:
The number 16 fits into 145 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 429.0
If we take 144 away from 145, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 16

Moving on to step 5:
16 goes into 11 0 times with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 4290.0
The remainder is 11 after subtracting 0 from 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 16

Going ahead to step 6:
The number 16 fits into 116 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 42907.0
If we subtract 112 from 116, 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.

Advancing to step 7:
16 can be fit into 40 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 42907.2
Deduct 32 from 40 and we're left with 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 8:
When dividing 80 by 16, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 42907.25
Deduct 80 from 80 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.

Advancing to step 9:
0 divided by 16 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 42907.25
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.

Let's proceed to step 10:
16 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 42907.25
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.

The quotient of the division is 42907.25, and the remainder is 0.0.
