We divide 668934 by 5
We want to figure out the number of times 668934 can be divided by 5.

Advancing to step 1:
6 divided by 5 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 5 from 6 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 5

Going ahead to step 2:
If we divide 16 by 5, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 15 away from 16, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 5

Moving on to step 3:
5 goes into 18 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 133.0
Deduct 15 from 18 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 5

Moving on to step 4:
39 divided by 5 is 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 1337.0
Subtract 35 from 39 to get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 5

On to step 5:
If we divide 43 by 5, we get 8 and a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 13378.0
Subtract 40 from 43 to get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 5

Going ahead to step 6:
If we divide 34 by 5, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 133786.0
Subtract 30 from 34 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.

On to step 7:
The number 5 fits into 40 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 133786.8
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.

Let's proceed to step 8:
When dividing 0 by 5, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 133786.8
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.

Step 9:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 133786.8
If we take 0 away from 0, we end up 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 133786.8 with a remainder of 0.0.
