We divide 187004 by 20
The aim is to understand the frequency of 20 in 187004.

Step 1:
1 divided by 20 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 20

On to step 2:
If we divide 18 by 20, we get 0 and a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 20

Step 3:
187 divided by 20 is 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 180 from 187 and we're left with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 20

On to step 4:
70 divided by 20 is 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
Deduct 60 from 70 and we're left with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 20

Moving on to step 5:
If we divide 100 by 20, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 935.0
Subtract 100 from 100 to get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 20

Step 6:
20 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 9350.0
Subtracting 0 from 4 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
If we divide 40 by 20, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 9350.2
If we subtract 40 from 40, 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.

Going ahead to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 9350.2
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.

Advancing to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9350.2
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.

The quotient of the division is 9350.2, and the remainder is 0.0.
