408789 ÷ 5 
Our goal is to divide 408789 by 5.

Advancing to step 1:
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: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 5

Advancing to step 2:
5 goes into 40 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 40 from 40, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 5

Going ahead to step 3:
When dividing 8 by 5, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 81.0
Subtract 5 from 8 to get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 5

Moving on to step 4:
5 can be fit into 37 7 times, resulting in a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 817.0
Deduct 35 from 37 and we're left with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 5

On to step 5:
5 goes into 28 5 times with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 8175.0
If we take 25 away from 28, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 5

On to step 6:
When dividing 39 by 5, we get 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 81757.0
The remainder is 4 after subtracting 35 from 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
5 goes into 40 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 81757.8
Deduct 40 from 40 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.

On 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: 81757.8
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.

Step 9:
5 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 81757.8
Subtract 0 from 0 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.

After the division, we end up with 81757.8 and a remainder of 0.0.
