We look at the division of 211560 by 23 
The aim is to understand the frequency of 23 in 211560.

Step 1:
2 divided by 23 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 23

Advancing to step 2:
The number 23 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 23

Let's proceed to step 3:
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: 9.0
Subtract 207 from 211 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 23

Moving on to step 4:
23 goes into 45 1 times with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Deduct 23 from 45 and we're left with 22.
Fetch the next digit (6) from the dividend, attach it to 22 and continue: 226 / 23

Step 5:
When dividing 226 by 23, we get 9 with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 919.0
Deduct 207 from 226 and we're left with 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 23

Advancing to step 6:
If we divide 190 by 23, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 9198.0
Subtract 184 from 190 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
23 goes into 60 2 times with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 9198.2
If we subtract 46 from 60, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
When dividing 140 by 23, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 9198.26
The remainder is 2 after subtracting 138 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
23 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 9198.26
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
23 goes into 200 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 9198.2608
If we subtract 184 from 200, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
23 can be fit into 160 6 times, resulting in a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 9198.26086
The remainder is 22 after subtracting 138 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
23 goes into 220 9 times with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 9198.260869
Subtract 207 from 220 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 13:
23 can be fit into 130 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 9198.2608695
The remainder is 15 after subtracting 115 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
150 divided by 23 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 9198.26086956
Deduct 138 from 150 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 9198.26086956 with a remaining 1.2e-08.
