We divide 668309 by 5
Our goal is to divide 668309 by 5.

Step 1:
When dividing 6 by 5, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 5 away from 6, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 5

On to step 2:
The number 5 fits into 16 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 15 from 16 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 5

Advancing to step 3:
5 goes into 18 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 133.0
If we take 15 away from 18, we end up with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 5

Step 4:
33 divided by 5 is 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 1336.0
If we take 30 away from 33, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 5

Advancing to step 5:
5 goes into 30 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 13366.0
If we take 30 away from 30, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 5

Moving on to step 6:
When dividing 9 by 5, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 133661.0
Subtract 5 from 9 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
40 divided by 5 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 133661.8
If we subtract 40 from 40, 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 8:
When dividing 0 by 5, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 133661.8
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.

Step 9:
If we divide 0 by 5, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 133661.8
The remainder is 0 after subtracting 0 from 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 133661.8 with a remainder of 0.0.
