We divide 55290 by 20
We want to figure out the number of times 55290 can be divided by 20.

Going ahead to step 1:
5 divided by 20 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 20

Let's proceed to step 2:
20 goes into 55 2 times with a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 15 after subtracting 40 from 55.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 20

Advancing to step 3:
20 can be fit into 152 7 times, resulting in a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we subtract 140 from 152, we get 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 20

Let's proceed to step 4:
20 goes into 129 6 times with a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 276.0
The remainder is 9 after subtracting 120 from 129.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 20

Moving on to step 5:
20 can be fit into 90 4 times, resulting in a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 2764.0
Subtract 80 from 90 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 6:
20 goes into 100 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2764.5
If we take 100 away from 100, 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.

On to step 7:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2764.5
Subtracting 0 from 0 leaves us 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.

Step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2764.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 2764.5 and a remainder of 0.0.
