615226 ÷ 20 
The aim is to understand the frequency of 20 in 615226.

Advancing to step 1:
The number 20 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 20

Let's proceed to step 2:
When dividing 61 by 20, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 60 from 61, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 20

Advancing to step 3:
20 goes into 15 0 times with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we take 0 away from 15, we end up with 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 20

Advancing to step 4:
If we divide 152 by 20, we get 7 and a remainder of 12.
The next digit of our result is 7. 
Result so far: 307.0
The remainder is 12 after subtracting 140 from 152.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 20

Going ahead to step 5:
When dividing 122 by 20, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 3076.0
The remainder is 2 after subtracting 120 from 122.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 20

On to step 6:
The number 20 fits into 26 1 times, leaving a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 30761.0
If we subtract 20 from 26, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
When dividing 60 by 20, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 30761.3
Deduct 60 from 60 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.

Going ahead to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 30761.3
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.

Moving on to step 9:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30761.3
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.

The final result is 30761.3 with a remainder of 0.0.
