688182 ÷ 2 
We're looking to find how many times 2 goes into 688182.

Step 1:
If we divide 6 by 2, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 6 from 6 and we're left with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 2

Advancing to step 2:
8 divided by 2 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we subtract 8 from 8, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 2

On to step 3:
2 can be fit into 8 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 344.0
If we subtract 8 from 8, we get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

Moving on to step 4:
The number 2 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 3440.0
If we subtract 0 from 1, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 2

Let's proceed to step 5:
The number 2 fits into 18 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 34409.0
If we subtract 18 from 18, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 2

Let's proceed to step 6:
2 can be fit into 2 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 344091.0
The remainder is 0 after subtracting 2 from 2.
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 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 344091.0
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.

Going ahead to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 344091.0
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.

The final result is 344091.0 with a remainder of 0.0.
