Let's divide 55164220 by 20
Our goal is to divide 55164220 by 20.

Advancing to step 1:
5 divided by 20 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 20

Going ahead to step 2:
20 goes into 55 2 times with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 40 from 55 and we're left with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 20

Advancing to step 3:
151 divided by 20 is 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Subtract 140 from 151 to get 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 20

Advancing to step 4:
When dividing 116 by 20, we get 5 with a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 275.0
The remainder is 16 after subtracting 100 from 116.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 20

Going ahead to step 5:
20 goes into 164 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 2758.0
Subtracting 160 from 164 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 20

On to step 6:
When dividing 42 by 20, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 27582.0
If we take 40 away from 42, we end up with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 20

Moving on to step 7:
If we divide 22 by 20, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 275821.0
If we take 20 away from 22, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 20

Advancing to step 8:
If we divide 20 by 20, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 2758211.0
Subtracting 20 from 20 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.

Going ahead to step 9:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2758211.0
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.

Moving on to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2758211.0
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.

After the division, we end up with 2758211.0 and a remainder of 0.0.
