418408 ÷ 80 
Our goal is to divide 418408 by 80.

Step 1:
If we divide 4 by 80, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 80

Step 2:
41 divided by 80 is 0 with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Include the next digit (8) from the dividend after 41, then repeat: 418 / 80

Let's proceed to step 3:
When dividing 418 by 80, we get 5 with a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 400 from 418 leaves us with 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 80

Advancing to step 4:
If we divide 184 by 80, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 52.0
Subtract 160 from 184 to get 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 80

Step 5:
The number 80 fits into 240 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 523.0
If we take 240 away from 240, we end up with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 80

Moving on to step 6:
The number 80 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 5230.0
Subtract 0 from 8 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
80 can be fit into 80 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 5230.1
Subtracting 80 from 80 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.

On to step 8:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5230.1
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:
0 divided by 80 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5230.1
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.

Our division results in 5230.1 with a remaining 0.0.
