We're dividing 668461 by 5 
We want to divide 668461 by 5.

Going ahead to step 1:
5 goes into 6 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 1 after subtracting 5 from 6.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 5

Moving on to step 2:
The number 5 fits into 16 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 15 from 16 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 5

Let's proceed to step 3:
If we divide 18 by 5, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 133.0
If we subtract 15 from 18, we get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 5

Step 4:
When dividing 34 by 5, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 1336.0
Subtracting 30 from 34 leaves us with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 5

On to step 5:
5 can be fit into 46 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 13369.0
Subtract 45 from 46 to get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 5

Advancing to step 6:
5 goes into 11 2 times with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 133692.0
Deduct 10 from 11 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
5 can be fit into 10 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 133692.2
Deduct 10 from 10 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.

Going ahead to step 8:
0 divided by 5 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 133692.2
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.

Let's proceed to 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: 133692.2
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.

The final outcome is 133692.2, with a leftover of 0.0.
