552815 ÷ 45 
Our goal is to divide 552815 by 45.

Going ahead to step 1:
5 divided by 45 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 45

Going ahead to step 2:
When dividing 55 by 45, we get 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 45 from 55 and we're left with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 45

Let's proceed to step 3:
When dividing 102 by 45, we get 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 90 from 102 leaves us with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 45

Moving on to step 4:
45 can be fit into 128 2 times, resulting in a remainder of 38.
The next digit of our result is 2. 
Result so far: 122.0
The remainder is 38 after subtracting 90 from 128.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 45

Step 5:
If we divide 381 by 45, we get 8 and a remainder of 21.
The next digit of our result is 8. 
Result so far: 1228.0
The remainder is 21 after subtracting 360 from 381.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 45

Advancing to step 6:
215 divided by 45 is 4 with a remainder of 35.
The next digit of our result is 4. 
Result so far: 12284.0
The remainder is 35 after subtracting 180 from 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
When dividing 350 by 45, we get 7 with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 12284.7
Subtract 315 from 350 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 8:
350 divided by 45 is 7 with a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 12284.77
If we take 315 away from 350, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 12284.77 with a remaining 0.035.
