We're dividing 216019 by 23 
The aim is to understand the frequency of 23 in 216019.

Step 1:
23 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 23

Let's proceed to step 2:
23 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 23

Let's proceed to step 3:
23 can be fit into 216 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 207 away from 216, we end up with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 23

On to step 4:
If we divide 90 by 23, we get 3 and a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 93.0
Subtracting 69 from 90 leaves us with 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 23

Moving on to step 5:
23 can be fit into 211 9 times, resulting in a remainder of 4.
The next digit of our result is 9. 
Result so far: 939.0
If we subtract 207 from 211, we get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 23

Going ahead to step 6:
49 divided by 23 is 2 with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 9392.0
If we take 46 away from 49, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
When dividing 30 by 23, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 9392.1
If we subtract 23 from 30, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
The number 23 fits into 70 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 9392.13
Deduct 69 from 70 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
The number 23 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 9392.13
The remainder is 10 after subtracting 0 from 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 10:
23 goes into 100 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 9392.1304
The remainder is 8 after subtracting 92 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
The number 23 fits into 80 3 times, leaving a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 9392.13043
Subtracting 69 from 80 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
110 divided by 23 is 4 with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 9392.130434
The remainder is 18 after subtracting 92 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
The number 23 fits into 180 7 times, leaving a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 9392.1304347
The remainder is 19 after subtracting 161 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 14:
190 divided by 23 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 9392.13043478
Subtracting 184 from 190 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 9392.13043478 with a remainder of 6e-09.
