975412 divided by 23 
The aim is to understand the frequency of 23 in 975412.

Advancing to step 1:
23 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 23

On to step 2:
If we divide 97 by 23, we get 4 and a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 92 away from 97, we end up with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 23

Going ahead to step 3:
55 divided by 23 is 2 with a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Subtracting 46 from 55 leaves us with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 23

Going ahead to step 4:
94 divided by 23 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 424.0
Subtracting 92 from 94 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 23

Step 5:
When dividing 21 by 23, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 4240.0
If we subtract 0 from 21, we get 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 23

Moving on to step 6:
The number 23 fits into 212 9 times, leaving a remainder of 5.
The next digit of our result is 9. 
Result so far: 42409.0
Deduct 207 from 212 and we're left 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:
50 divided by 23 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 42409.2
If we subtract 46 from 50, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
23 can be fit into 40 1 times, resulting in a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 42409.21
Subtract 23 from 40 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 9:
23 goes into 170 7 times with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 42409.217
Subtract 161 from 170 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 10:
23 can be fit into 90 3 times, resulting in a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 42409.2173
If we subtract 69 from 90, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 11:
The number 23 fits into 210 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 42409.21739
If we take 207 away from 210, 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.

Going ahead to step 12:
30 divided by 23 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 42409.217391
The remainder is 7 after subtracting 23 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 13:
23 can be fit into 70 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 42409.2173913
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.

Let's proceed to step 14:
23 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 42409.2173913
If we subtract 0 from 10, we 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.

Our division results in 42409.2173913 with a remaining 1e-08.
