We're dividing 686712 by 16 
Our goal is to divide 686712 by 16.

Let's proceed to step 1:
The number 16 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 16

On to step 2:
The number 16 fits into 68 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 64 away from 68, we end up with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 16

On to step 3:
16 can be fit into 46 2 times, resulting in a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 42.0
The remainder is 14 after subtracting 32 from 46.
Bring next digit (7) of the dividend behind the 14 and repeat the process: 147 / 16

Advancing to step 4:
When dividing 147 by 16, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 429.0
If we subtract 144 from 147, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 16

Let's proceed to step 5:
The number 16 fits into 31 1 times, leaving a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 4291.0
Subtract 16 from 31 to get 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 16

Moving on to step 6:
If we divide 152 by 16, we get 9 and a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 42919.0
Subtracting 144 from 152 leaves us 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.

Step 7:
If we divide 80 by 16, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 42919.5
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.

Going ahead to step 8:
0 divided by 16 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 42919.5
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.

On to step 9:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 42919.5
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.

The final result is 42919.5 with a remainder of 0.0.
