54541801 ÷ 450 
Our goal is to divide 54541801 by 450.

Going ahead to step 1:
When dividing 5 by 450, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 450

Moving on to step 2:
The number 450 fits into 54 0 times, leaving a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Include the next digit (5) from the dividend after 54, then repeat: 545 / 450

On to step 3:
The number 450 fits into 545 1 times, leaving a remainder of 95.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 95 after subtracting 450 from 545.
Append the next digit (4) from the dividend to 95 and continue with: 954 / 450

Let's proceed to step 4:
450 goes into 954 2 times with a remainder of 54.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 900 from 954 leaves us with 54.
Bring next digit (1) of the dividend behind the 54 and repeat the process: 541 / 450

Advancing to step 5:
541 divided by 450 is 1 with a remainder of 91.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
Subtracting 450 from 541 leaves us with 91.
Bring next digit (8) of the dividend behind the 91 and repeat the process: 918 / 450

Step 6:
918 divided by 450 is 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 1212.0
If we subtract 900 from 918, we get 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 450

Going ahead to step 7:
450 goes into 180 0 times with a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 12120.0
Deduct 0 from 180 and we're left with 180.
Fetch the next digit (1) from the dividend, attach it to 180 and continue: 1801 / 450

On to step 8:
1801 divided by 450 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 121204.0
If we take 1800 away from 1801, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
450 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 121204.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
450 goes into 100 0 times with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 121204.0
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 121204.0 with a remainder of 0.1.
