204090 ÷ 54 
We want to figure out the number of times 204090 can be divided by 54.

Moving on to step 1:
When dividing 2 by 54, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 54

Going ahead to step 2:
When dividing 20 by 54, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 54

Advancing to step 3:
54 can be fit into 204 3 times, resulting in a remainder of 42.
The next digit of our result is 3. 
Result so far: 3.0
If we take 162 away from 204, we end up with 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 54

Let's proceed to step 4:
54 goes into 420 7 times with a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 37.0
The remainder is 42 after subtracting 378 from 420.
Append the next digit (9) from the dividend to 42 and continue with: 429 / 54

On to step 5:
If we divide 429 by 54, we get 7 and a remainder of 51.
Use 7 as the next digit of our solution. 
Result so far: 377.0
If we take 378 away from 429, we end up with 51.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 54

Step 6:
510 divided by 54 is 9 with a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 3779.0
If we take 486 away from 510, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
54 can be fit into 240 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 3779.4
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
If we divide 240 by 54, we get 4 and a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 3779.44
If we take 216 away from 240, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 3779.44 with a remainder of 0.024.
