669155 ÷ 20 
The aim is to understand the frequency of 20 in 669155.

Advancing to step 1:
20 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 20

Step 2:
The number 20 fits into 66 3 times, leaving a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 60 from 66 to get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 20

Let's proceed to step 3:
The number 20 fits into 69 3 times, leaving a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we subtract 60 from 69, we get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 20

Going ahead to step 4:
20 goes into 91 4 times with a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 334.0
Subtracting 80 from 91 leaves us with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 20

Moving on to step 5:
115 divided by 20 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 3345.0
Deduct 100 from 115 and we're left with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 20

Let's proceed to step 6:
155 divided by 20 is 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 33457.0
Subtracting 140 from 155 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
The number 20 fits into 150 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 33457.7
If we take 140 away from 150, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 33457.75
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.

Step 9:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 33457.75
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.

Let's proceed to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 33457.75
If we take 0 away from 0, we end up 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.

In conclusion, the division gives 33457.75 with a balance of 0.0.
