Let's divide 128159 by 20
The aim is to understand the frequency of 20 in 128159.

Moving on to step 1:
20 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 20

Moving on to step 2:
When dividing 12 by 20, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 20

Step 3:
20 goes into 128 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 120 from 128 leaves us with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 20

Let's proceed to step 4:
81 divided by 20 is 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 64.0
The remainder is 1 after subtracting 80 from 81.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 20

Advancing to step 5:
When dividing 15 by 20, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 640.0
If we subtract 0 from 15, we get 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 20

Moving on to step 6:
20 goes into 159 7 times with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 6407.0
Deduct 140 from 159 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
190 divided by 20 is 9 with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 6407.9
The remainder is 10 after subtracting 180 from 190.
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:
If we divide 100 by 20, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 6407.95
Subtracting 100 from 100 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.

Moving on to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6407.95
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.

Going ahead to step 10:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6407.95
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.

The quotient of the division is 6407.95, and the remainder is 0.0.
