We're dividing 13329068 by 20 
The aim is to understand the frequency of 20 in 13329068.

Going ahead to step 1:
If we divide 1 by 20, we get 0 and 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 (3) of the dividend behind the 1 and repeat the process: 13 / 20

Step 2:
The number 20 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 20

Moving on to step 3:
20 goes into 133 6 times with a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 120 from 133 to get 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 20

Going ahead to step 4:
If we divide 132 by 20, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Deduct 120 from 132 and we're left with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 20

Moving on to step 5:
20 can be fit into 129 6 times, resulting in a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 666.0
Deduct 120 from 129 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 20

Advancing to step 6:
90 divided by 20 is 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 6664.0
The remainder is 10 after subtracting 80 from 90.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 20

Step 7:
20 can be fit into 106 5 times, resulting in a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 66645.0
Subtracting 100 from 106 leaves us with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 20

Moving on to step 8:
68 divided by 20 is 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 666453.0
Deduct 60 from 68 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
20 can be fit into 80 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 666453.4
If we subtract 80 from 80, 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 10:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 666453.4
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.

Let's proceed to step 11:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 666453.4
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.

After the division, we end up with 666453.4 and a remainder of 0.0.
