We're dividing 547999 by 45 
Our goal is to divide 547999 by 45.

On to step 1:
5 divided by 45 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 45

Advancing to step 2:
When dividing 54 by 45, we get 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 45 from 54 and we're left with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 45

On to step 3:
The number 45 fits into 97 2 times, leaving a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 90 from 97 leaves us with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 45

Let's proceed to step 4:
When dividing 79 by 45, we get 1 with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 121.0
If we subtract 45 from 79, we get 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 45

Let's proceed to step 5:
The number 45 fits into 349 7 times, leaving a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 1217.0
The remainder is 34 after subtracting 315 from 349.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 45

Advancing to step 6:
349 divided by 45 is 7 with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 12177.0
The remainder is 34 after subtracting 315 from 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
340 divided by 45 is 7 with a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 12177.7
The remainder is 25 after subtracting 315 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
If we divide 250 by 45, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 12177.75
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.

Moving on to step 9:
45 goes into 250 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 12177.755
Deduct 225 from 250 and we're left 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.

Our division results in 12177.755 with a remaining 0.0025.
