We're dividing 668803 by 4 
We want to figure out the number of times 668803 can be divided by 4.

Let's proceed to step 1:
4 can be fit into 6 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 4 away from 6, we end up with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 4

Advancing to step 2:
When dividing 26 by 4, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 24 from 26 to get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 4

Step 3:
4 goes into 28 7 times with a remainder of 0.
The next digit of our result is 7. 
Result so far: 167.0
The remainder is 0 after subtracting 28 from 28.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 4

Going ahead 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: 1672.0
Deduct 8 from 8 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 4

Advancing to step 5:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 16720.0
Deduct 0 from 0 and we're left with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 4

Let's proceed to step 6:
3 divided by 4 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 167200.0
Subtract 0 from 3 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:
4 goes into 30 7 times with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 167200.7
Subtracting 28 from 30 leaves us 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.

Step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 167200.75
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.

Let's proceed to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 167200.75
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:
If we divide 0 by 4, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 167200.75
Subtract 0 from 0 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.

Our division results in 167200.75 with a remaining 0.0.
