We're dividing 688430 by 16 
We're looking to find how many times 16 goes into 688430.

Going ahead to step 1:
16 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 16

Step 2:
16 can be fit into 68 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 4.0
If we take 64 away from 68, we end up with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 16

On to step 3:
16 can be fit into 48 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtract 48 from 48 to get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 16

On to step 4:
16 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 430.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 16

Going ahead to step 5:
The number 16 fits into 43 2 times, leaving a remainder of 11.
The next digit of our result is 2. 
Result so far: 4302.0
The remainder is 11 after subtracting 32 from 43.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 16

On to step 6:
The number 16 fits into 110 6 times, leaving a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 43026.0
Subtract 96 from 110 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
The number 16 fits into 140 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 43026.8
Deduct 128 from 140 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
The number 16 fits into 120 7 times, leaving a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 43026.87
If we take 112 away from 120, 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.

Advancing to step 9:
16 goes into 80 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 43026.875
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.

Step 10:
If we divide 0 by 16, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 43026.875
If we subtract 0 from 0, 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.

Advancing to step 11:
When dividing 0 by 16, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 43026.875
If we subtract 0 from 0, 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.

The quotient of the division is 43026.875, and the remainder is 0.0.
