321765 ÷ 20 
The aim is to understand the frequency of 20 in 321765.

Moving on to step 1:
When dividing 3 by 20, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 20

Step 2:
The number 20 fits into 32 1 times, leaving a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 12 after subtracting 20 from 32.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 20

Advancing to step 3:
If we divide 121 by 20, we get 6 and a remainder of 1.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 120 from 121, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 20

Let's proceed to step 4:
When dividing 17 by 20, we get 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 160.0
Subtract 0 from 17 to get 17.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 20

Moving on to step 5:
The number 20 fits into 176 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 1608.0
Deduct 160 from 176 and we're left with 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 20

Going ahead to step 6:
When dividing 165 by 20, we get 8 with a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 16088.0
Subtracting 160 from 165 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
When dividing 50 by 20, we get 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 16088.2
Subtract 40 from 50 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 16088.25
If we take 100 away from 100, 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.

Advancing to step 9:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 16088.25
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 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 16088.25
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 16088.25, with a leftover of 0.0.
