We look at the division of 689955 by 2 
Let's see how many times 2 fits into 689955.

Step 1:
2 can be fit into 6 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 6 from 6, we get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 2

Going ahead to step 2:
The number 2 fits into 8 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Subtract 8 from 8 to get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 2

Advancing to step 3:
The number 2 fits into 9 4 times, leaving a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 344.0
The remainder is 1 after subtracting 8 from 9.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 2

On to step 4:
2 goes into 19 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 3449.0
If we subtract 18 from 19, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 2

Advancing to step 5:
When dividing 15 by 2, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 34497.0
If we take 14 away from 15, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 2

Moving on to step 6:
If we divide 15 by 2, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 344977.0
If we take 14 away from 15, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 344977.5
If we subtract 10 from 10, 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.

Moving on to step 8:
2 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 344977.5
Subtracting 0 from 0 leaves us 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:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 344977.5
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.

The final result is 344977.5 with a remainder of 0.0.
