680479 divided by 4 
We're looking to find how many times 4 goes into 680479.

On to step 1:
When dividing 6 by 4, we get 1 with 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.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 4

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
If we subtract 28 from 28, we get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 4

Step 3:
4 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 170.0
If we subtract 0 from 0, we get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 4

Let's proceed to step 4:
If we divide 4 by 4, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1701.0
If we subtract 4 from 4, we get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 4

Step 5:
4 can be fit into 7 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 17011.0
Subtracting 4 from 7 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 4

Moving on to step 6:
When dividing 39 by 4, we get 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 170119.0
Subtracting 36 from 39 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
If we divide 30 by 4, we get 7 and a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 170119.7
Deduct 28 from 30 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 170119.75
Subtract 20 from 20 to 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 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 170119.75
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.

Let's proceed to step 10:
4 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 170119.75
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.

After the division, we end up with 170119.75 and a remainder of 0.0.
