219787 ÷ 20 
The aim is to understand the frequency of 20 in 219787.

Let's proceed to step 1:
If we divide 2 by 20, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 20

Step 2:
20 goes into 21 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 1 after subtracting 20 from 21.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 20

Let's proceed to step 3:
If we divide 19 by 20, we get 0 and a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 19 after subtracting 0 from 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 20

On to step 4:
20 can be fit into 197 9 times, resulting in a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 109.0
The remainder is 17 after subtracting 180 from 197.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 20

Advancing to step 5:
If we divide 178 by 20, we get 8 and a remainder of 18.
The next digit of our result is 8. 
Result so far: 1098.0
If we take 160 away from 178, we end up with 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 20

Let's proceed to step 6:
20 can be fit into 187 9 times, resulting in a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 10989.0
Deduct 180 from 187 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
70 divided by 20 is 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 10989.3
Subtracting 60 from 70 leaves us 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:
If we divide 100 by 20, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 10989.35
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.

Step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10989.35
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.

Going ahead 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: 10989.35
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.

In conclusion, the division gives 10989.35 with a balance of 0.0.
