We're dividing 408111 by 54 
We want to figure out the number of times 408111 can be divided by 54.

On to step 1:
54 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 54

Advancing to step 2:
When dividing 40 by 54, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 54

Let's proceed to step 3:
When dividing 408 by 54, we get 7 with a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 30 after subtracting 378 from 408.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 54

Advancing to step 4:
The number 54 fits into 301 5 times, leaving a remainder of 31.
Put 5 as the next digit of the answer. 
Result so far: 75.0
Subtract 270 from 301 to get 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 54

Advancing to step 5:
The number 54 fits into 311 5 times, leaving a remainder of 41.
The next digit of our result is 5. 
Result so far: 755.0
If we subtract 270 from 311, we get 41.
Include the next digit (1) from the dividend after 41, then repeat: 411 / 54

Let's proceed to step 6:
When dividing 411 by 54, we get 7 with a remainder of 33.
The next digit of our result is 7. 
Result so far: 7557.0
If we take 378 away from 411, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 7:
330 divided by 54 is 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 7557.6
The remainder is 6 after subtracting 324 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
54 goes into 60 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 7557.61
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
54 can be fit into 60 1 times, resulting in a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 7557.611
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 7557.611, with a leftover of 0.0006.
