We look at the division of 420497 by 5 
Let's see how many times 5 fits into 420497.

Advancing to step 1:
If we divide 4 by 5, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 5

Moving on to step 2:
5 can be fit into 42 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 40 from 42 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 5

On to step 3:
5 can be fit into 20 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 84.0
Subtract 20 from 20 to get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 5

On to step 4:
The number 5 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 840.0
Subtract 0 from 4 to get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 5

Moving on to step 5:
49 divided by 5 is 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 8409.0
If we take 45 away from 49, we end up with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 5

Going ahead to step 6:
The number 5 fits into 47 9 times, leaving a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 84099.0
The remainder is 2 after subtracting 45 from 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
The number 5 fits into 20 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 84099.4
If we take 20 away from 20, 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.

On to step 8:
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: 84099.4
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:
If we divide 0 by 5, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 84099.4
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 result is 84099.4 with a remainder of 0.0.
