We look at the division of 289761 by 20 
The aim is to understand the frequency of 20 in 289761.

Moving on to step 1:
20 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 20

On to step 2:
28 divided by 20 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 20 from 28 to get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 20

Going ahead to step 3:
If we divide 89 by 20, we get 4 and a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 9 after subtracting 80 from 89.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 20

Advancing to step 4:
20 goes into 97 4 times with a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 144.0
If we take 80 away from 97, we end up with 17.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 20

Step 5:
If we divide 176 by 20, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 1448.0
The remainder is 16 after subtracting 160 from 176.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 20

Moving on to step 6:
If we divide 161 by 20, we get 8 and a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 14488.0
Subtract 160 from 161 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
20 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 14488.0
If we take 0 away from 10, 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:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 14488.05
Deduct 100 from 100 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 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 14488.05
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.

On to step 10:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14488.05
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.

The final result is 14488.05 with a remainder of 0.0.
