549018 divided by 20 
We want to figure out the number of times 549018 can be divided by 20.

Let's proceed to step 1:
The number 20 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
The remainder is 5 after subtracting 0 from 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 20

Step 2:
When dividing 54 by 20, we get 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 14 after subtracting 40 from 54.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 20

On to step 3:
The number 20 fits into 149 7 times, leaving a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
If we subtract 140 from 149, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 20

Moving on to step 4:
If we divide 90 by 20, we get 4 and a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 274.0
If we subtract 80 from 90, we get 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 20

Moving on to step 5:
If we divide 101 by 20, we get 5 and a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 2745.0
If we take 100 away from 101, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 20

Step 6:
20 goes into 18 0 times with a remainder of 18.
The next digit of our result is 0. 
Result so far: 27450.0
The remainder is 18 after subtracting 0 from 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
The number 20 fits into 180 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 27450.9
If we take 180 away from 180, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 27450.9
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 27450.9
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 27450.9 with a remaining 0.0.
