We look at the division of 969522 by 23 
The aim is to understand the frequency of 23 in 969522.

On to step 1:
23 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 23

Let's proceed to step 2:
If we divide 96 by 23, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 4 after subtracting 92 from 96.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 23

On to step 3:
When dividing 49 by 23, we get 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtracting 46 from 49 leaves us with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 23

Step 4:
35 divided by 23 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 421.0
Subtract 23 from 35 to get 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 23

Advancing to step 5:
If we divide 122 by 23, we get 5 and a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 4215.0
The remainder is 7 after subtracting 115 from 122.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 23

Let's proceed to step 6:
The number 23 fits into 72 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 42153.0
If we subtract 69 from 72, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
30 divided by 23 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 42153.1
Subtracting 23 from 30 leaves us 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.

Step 8:
23 goes into 70 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 42153.13
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.

Step 9:
The number 23 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 42153.13
Deduct 0 from 10 and we're left 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.

On to step 10:
23 goes into 100 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 42153.1304
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.

Step 11:
When dividing 80 by 23, we get 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 42153.13043
Deduct 69 from 80 and we're left 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.

On to step 12:
If we divide 110 by 23, we get 4 and a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 42153.130434
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 13:
If we divide 180 by 23, we get 7 and a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 42153.1304347
Subtract 161 from 180 to get 19.
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:
23 can be fit into 190 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 42153.13043478
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.

The final outcome is 42153.13043478, with a leftover of 6e-09.
