680619 ÷ 4 
Our goal is to divide 680619 by 4.

Moving on to step 1:
If we divide 6 by 4, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 2 after subtracting 4 from 6.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 4

On to step 2:
The number 4 fits into 28 7 times, leaving a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 28 from 28 leaves us with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 4

Advancing to step 3:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 170.0
If we subtract 0 from 0, we get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 4

Advancing to step 4:
When dividing 6 by 4, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1701.0
Subtract 4 from 6 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 4

Step 5:
4 can be fit into 21 5 times, resulting in a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 17015.0
Deduct 20 from 21 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 4

On to step 6:
When dividing 19 by 4, we get 4 with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 170154.0
Subtract 16 from 19 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
30 divided by 4 is 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 170154.7
If we subtract 28 from 30, 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.

On to step 8:
4 goes into 20 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 170154.75
Deduct 20 from 20 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.

Moving on 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: 170154.75
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.

Let's proceed to step 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 170154.75
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.

The final outcome is 170154.75, with a leftover of 0.0.
