554800 ÷ 45 
Let's see how many times 45 fits into 554800.

Step 1:
If we divide 5 by 45, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 45

Step 2:
45 can be fit into 55 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 10 after subtracting 45 from 55.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 45

Let's proceed to step 3:
45 goes into 104 2 times with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 90 away from 104, we end up with 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 45

On to step 4:
If we divide 148 by 45, we get 3 and a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 123.0
The remainder is 13 after subtracting 135 from 148.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 45

Going ahead to step 5:
45 goes into 130 2 times with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 1232.0
Deduct 90 from 130 and we're left with 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 45

On to step 6:
When dividing 400 by 45, we get 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 12328.0
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 7:
45 can be fit into 400 8 times, resulting in a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 12328.8
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
The number 45 fits into 400 8 times, leaving a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 12328.88
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 12328.88 and a remainder of 0.04.
