We divide 684590 by 2
Let's see how many times 2 fits into 684590.

Moving on to step 1:
The number 2 fits into 6 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 6 from 6 leaves us with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 2

Moving on to step 2:
2 can be fit into 8 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 8 from 8, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 2

Step 3:
When dividing 4 by 2, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 342.0
The remainder is 0 after subtracting 4 from 4.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

Advancing to step 4:
When dividing 5 by 2, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 3422.0
If we subtract 4 from 5, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

Let's proceed to step 5:
The number 2 fits into 19 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 34229.0
If we subtract 18 from 19, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 2

Going ahead to step 6:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 342295.0
Subtracting 10 from 10 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.

On to step 7:
2 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 342295.0
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.

Advancing to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 342295.0
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 quotient of the division is 342295.0, and the remainder is 0.0.
