We look at the division of 664907 by 4 
We want to figure out the number of times 664907 can be divided by 4.

Going ahead to step 1:
4 goes into 6 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 2 after subtracting 4 from 6.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 4

Moving on to step 2:
4 goes into 26 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 24 from 26 leaves us with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 4

On to step 3:
When dividing 24 by 4, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 166.0
Subtracting 24 from 24 leaves us with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 4

On to step 4:
When dividing 9 by 4, we get 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 1662.0
The remainder is 1 after subtracting 8 from 9.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 4

On to step 5:
4 can be fit into 10 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 16622.0
Subtracting 8 from 10 leaves us with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 4

Step 6:
The number 4 fits into 27 6 times, leaving a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 166226.0
The remainder is 3 after subtracting 24 from 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing 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: 166226.7
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.

Advancing to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 166226.75
Subtracting 20 from 20 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 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 166226.75
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.

Moving on 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: 166226.75
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.

The final result is 166226.75 with a remainder of 0.0.
