668449 divided by 5 
We want to figure out the number of times 668449 can be divided by 5.

Moving on to step 1:
If we divide 6 by 5, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 5 from 6, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 5

Let's proceed to step 2:
16 divided by 5 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 1 after subtracting 15 from 16.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 5

Step 3:
If we divide 18 by 5, we get 3 and a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 133.0
If we take 15 away from 18, we end up with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 5

Let's proceed to step 4:
If we divide 34 by 5, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 1336.0
If we take 30 away from 34, we end up with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 5

Advancing to step 5:
If we divide 44 by 5, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 13368.0
Subtracting 40 from 44 leaves us with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 5

Advancing to step 6:
The number 5 fits into 49 9 times, leaving a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 133689.0
Subtracting 45 from 49 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
When dividing 40 by 5, we get 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 133689.8
Subtract 40 from 40 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.

Going ahead to step 8:
5 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 133689.8
Subtracting 0 from 0 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.

Let's proceed to step 9:
5 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 133689.8
Subtracting 0 from 0 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.

After the division, we end up with 133689.8 and a remainder of 0.0.
