423458 divided by 5 
Let's see how many times 5 fits into 423458.

Advancing to step 1:
5 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 5

On to step 2:
42 divided by 5 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 40 away from 42, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 5

Going ahead to step 3:
5 goes into 23 4 times with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 84.0
The remainder is 3 after subtracting 20 from 23.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 5

Advancing to step 4:
The number 5 fits into 34 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 846.0
Subtracting 30 from 34 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 5

On to step 5:
When dividing 45 by 5, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 8469.0
The remainder is 0 after subtracting 45 from 45.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 5

Let's proceed to step 6:
8 divided by 5 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 84691.0
If we subtract 5 from 8, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
5 can be fit into 30 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 84691.6
If we take 30 away from 30, 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.

Let's proceed to step 8:
If we divide 0 by 5, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 84691.6
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.

Step 9:
5 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 84691.6
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 84691.6 with a remainder of 0.0.
