We divide 684854 by 4
We want to figure out the number of times 684854 can be divided by 4.

Moving on to step 1:
4 can be fit into 6 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 4 from 6 leaves us with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 4

On to step 2:
If we divide 28 by 4, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 28 from 28 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 4

Step 3:
4 goes into 4 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 171.0
The remainder is 0 after subtracting 4 from 4.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 4

Advancing to step 4:
When dividing 8 by 4, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 1712.0
The remainder is 0 after subtracting 8 from 8.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 4

Step 5:
5 divided by 4 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 17121.0
If we subtract 4 from 5, we get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 4

Let's proceed to step 6:
4 goes into 14 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 171213.0
If we subtract 12 from 14, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
4 goes into 20 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 171213.5
The remainder is 0 after subtracting 20 from 20.
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 8:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 171213.5
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.

Going ahead to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 171213.5
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 quotient of the division is 171213.5, and the remainder is 0.0.
