We divide 527409 by 20
The aim is to understand the frequency of 20 in 527409.

Advancing to step 1:
20 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 20

Let's proceed to step 2:
52 divided by 20 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 12 after subtracting 40 from 52.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 20

Going ahead to step 3:
20 can be fit into 127 6 times, resulting in a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 26.0
The remainder is 7 after subtracting 120 from 127.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 20

Moving on to step 4:
The number 20 fits into 74 3 times, leaving a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 263.0
If we subtract 60 from 74, we get 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 20

Moving on to step 5:
20 can be fit into 140 7 times, resulting in a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 2637.0
Subtract 140 from 140 to get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 20

Going ahead to step 6:
When dividing 9 by 20, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 26370.0
The remainder is 9 after subtracting 0 from 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
20 goes into 90 4 times with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 26370.4
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.

Advancing to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 26370.45
Subtract 100 from 100 to 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:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 26370.45
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.

Let's proceed to step 10:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 26370.45
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.

Our division results in 26370.45 with a remaining 0.0.
