We look at the division of 688389 by 16 
We want to figure out the number of times 688389 can be divided by 16.

On to step 1:
When dividing 6 by 16, we get 0 with 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.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 16

Moving on to step 2:
16 can be fit into 68 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 64 from 68 to get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 16

On to step 3:
16 goes into 48 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 43.0
Subtracting 48 from 48 leaves us with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 16

Step 4:
3 divided by 16 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 430.0
If we take 0 away from 3, we end up with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 16

Moving on to step 5:
38 divided by 16 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 4302.0
The remainder is 6 after subtracting 32 from 38.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 16

Going ahead to step 6:
When dividing 69 by 16, we get 4 with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 43024.0
If we take 64 away from 69, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
The number 16 fits into 50 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 43024.3
Deduct 48 from 50 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
If we divide 20 by 16, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 43024.31
Subtracting 16 from 20 leaves us 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 9:
16 can be fit into 40 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 43024.312
If we take 32 away from 40, we end up 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.

Moving on to step 10:
The number 16 fits into 80 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 43024.3125
The remainder is 0 after subtracting 80 from 80.
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 11:
The number 16 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 43024.3125
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.

Let's proceed to step 12:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 43024.3125
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.

In conclusion, the division gives 43024.3125 with a balance of 0.0.
