551482 ÷ 45 
Our goal is to divide 551482 by 45.

Going ahead to step 1:
The number 45 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 45

Step 2:
45 can be fit into 55 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 45 from 55 and we're left with 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 45

Advancing to step 3:
45 goes into 101 2 times with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 90 from 101 leaves us with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 45

Step 4:
The number 45 fits into 114 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 122.0
Subtracting 90 from 114 leaves us with 24.
Bring next digit (8) of the dividend behind the 24 and repeat the process: 248 / 45

Let's proceed to step 5:
When dividing 248 by 45, we get 5 with a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 1225.0
If we subtract 225 from 248, we get 23.
Grab the next digit (2) from the dividend, add it to 23, then carry on: 232 / 45

Advancing to step 6:
232 divided by 45 is 5 with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 12255.0
If we subtract 225 from 232, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
45 can be fit into 70 1 times, resulting in a remainder of 25.
The next digit of our result is 1. 
Result so far: 12255.1
The remainder is 25 after subtracting 45 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
250 divided by 45 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 12255.15
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
The number 45 fits into 250 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 12255.155
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

In conclusion, the division gives 12255.155 with a balance of 0.0025.
