We divide 285755 by 20
The aim is to understand the frequency of 20 in 285755.

On to step 1:
20 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 20

On to step 2:
20 can be fit into 28 1 times, resulting in a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 20 away from 28, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 20

Advancing to step 3:
85 divided by 20 is 4 with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 80 from 85 to get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 20

Step 4:
20 goes into 57 2 times with a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 142.0
If we subtract 40 from 57, we get 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 20

Going ahead to step 5:
When dividing 175 by 20, we get 8 with a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 1428.0
Subtract 160 from 175 to get 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 20

Going ahead to step 6:
20 can be fit into 155 7 times, resulting in a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 14287.0
The remainder is 15 after subtracting 140 from 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
The number 20 fits into 150 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 14287.7
Deduct 140 from 150 and we're left 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:
100 divided by 20 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 14287.75
If we subtract 100 from 100, 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.

Step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14287.75
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.

Moving on 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: 14287.75
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 outcome is 14287.75, with a leftover of 0.0.
