541200 ÷ 45 
Let's see how many times 45 fits into 541200.

Going ahead to step 1:
If we divide 5 by 45, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 45

Going ahead to step 2:
When dividing 54 by 45, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 45 from 54 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 45

Going ahead to step 3:
45 can be fit into 91 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 1 after subtracting 90 from 91.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 45

On to step 4:
When dividing 12 by 45, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 120.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 45

Going ahead to step 5:
45 goes into 120 2 times with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 1202.0
If we subtract 90 from 120, we get 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 45

Advancing to step 6:
300 divided by 45 is 6 with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 12026.0
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
45 can be fit into 300 6 times, resulting in a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 12026.6
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
45 goes into 300 6 times with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 12026.66
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 12026.66, and the remainder is 0.03.
