We look at the division of 595120 by 23 
The aim is to understand the frequency of 23 in 595120.

Let's proceed to step 1:
23 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 23

On to step 2:
59 divided by 23 is 2 with a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 46 away from 59, we end up with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 23

Let's proceed to step 3:
23 goes into 135 5 times with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
The remainder is 20 after subtracting 115 from 135.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 23

On to step 4:
23 can be fit into 201 8 times, resulting in a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 258.0
The remainder is 17 after subtracting 184 from 201.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 23

On to step 5:
If we divide 172 by 23, we get 7 and a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 2587.0
Subtract 161 from 172 to get 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 23

Let's proceed to step 6:
110 divided by 23 is 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 25874.0
If we take 92 away from 110, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
When dividing 180 by 23, we get 7 with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 25874.7
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.

Moving on to step 8:
If we divide 190 by 23, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 25874.78
Deduct 184 from 190 and we're left 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.

Going ahead to step 9:
When dividing 60 by 23, we get 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 25874.782
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.

On to step 10:
140 divided by 23 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 25874.7826
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 11:
23 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 25874.7826
If we take 0 away from 20, we end up 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.

On to step 12:
23 can be fit into 200 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 25874.782608
Subtract 184 from 200 to 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.

Moving on to step 13:
The number 23 fits into 160 6 times, leaving a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 25874.7826086
If we take 138 away from 160, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
The number 23 fits into 220 9 times, leaving a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 25874.78260869
If we take 207 away from 220, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 25874.78260869 with a remaining 1.3e-08.
