We look at the division of 704895 by 20 
The aim is to understand the frequency of 20 in 704895.

Step 1:
The number 20 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 20

Step 2:
20 can be fit into 70 3 times, resulting in a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 10 after subtracting 60 from 70.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 20

Let's proceed to step 3:
20 can be fit into 104 5 times, resulting in a remainder of 4.
The next digit of our result is 5. 
Result so far: 35.0
If we subtract 100 from 104, we get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 20

On to step 4:
If we divide 48 by 20, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 352.0
Subtracting 40 from 48 leaves us with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 20

On to step 5:
20 can be fit into 89 4 times, resulting in a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 3524.0
Subtracting 80 from 89 leaves us with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 20

Moving on to step 6:
The number 20 fits into 95 4 times, leaving a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 35244.0
If we subtract 80 from 95, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
When dividing 150 by 20, we get 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 35244.7
The remainder is 10 after subtracting 140 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
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: 35244.75
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.

On to step 9:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 35244.75
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 10:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 35244.75
Subtract 0 from 0 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.

The quotient of the division is 35244.75, and the remainder is 0.0.
