We divide 18527780 by 20
The aim is to understand the frequency of 20 in 18527780.

Let's proceed to step 1:
20 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 20

Moving on to step 2:
20 can be fit into 18 0 times, resulting in a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 20

Let's proceed to step 3:
20 goes into 185 9 times with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 5 after subtracting 180 from 185.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 20

Let's proceed to step 4:
The number 20 fits into 52 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 92.0
If we take 40 away from 52, we end up with 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 20

Step 5:
If we divide 127 by 20, we get 6 and a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 926.0
The remainder is 7 after subtracting 120 from 127.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 20

On to step 6:
77 divided by 20 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 9263.0
The remainder is 17 after subtracting 60 from 77.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 20

Moving on to step 7:
178 divided by 20 is 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 92638.0
Subtract 160 from 178 to get 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 20

Moving on to step 8:
20 goes into 180 9 times with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 926389.0
The remainder is 0 after subtracting 180 from 180.
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:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 926389.0
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.

Step 10:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 926389.0
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.

The final result is 926389.0 with a remainder of 0.0.
