Let's divide 309775 by 23
The aim is to understand the frequency of 23 in 309775.

Advancing to step 1:
23 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 23

On to step 2:
30 divided by 23 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 7 after subtracting 23 from 30.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 23

Advancing to step 3:
23 can be fit into 79 3 times, resulting in a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 69 from 79 leaves us with 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 23

Moving on to step 4:
When dividing 107 by 23, we get 4 with a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 134.0
If we take 92 away from 107, we end up with 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 23

Going ahead to step 5:
23 can be fit into 157 6 times, resulting in a remainder of 19.
The next digit of our result is 6. 
Result so far: 1346.0
Subtract 138 from 157 to get 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 23

Advancing to step 6:
23 can be fit into 195 8 times, resulting in a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 13468.0
Subtracting 184 from 195 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.

Let's proceed to step 7:
The number 23 fits into 110 4 times, leaving a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 13468.4
Subtract 92 from 110 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
The number 23 fits into 180 7 times, leaving a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 13468.47
If we subtract 161 from 180, we 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.

Let's proceed to step 9:
190 divided by 23 is 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 13468.478
If we subtract 184 from 190, we 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.

Advancing to step 10:
The number 23 fits into 60 2 times, leaving a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 13468.4782
If we take 46 away from 60, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
If we divide 140 by 23, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 13468.47826
Subtracting 138 from 140 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
20 divided by 23 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 13468.47826
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
The number 23 fits into 200 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 13468.4782608
If we take 184 away from 200, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
When dividing 160 by 23, we get 6 with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 13468.47826086
Subtracting 138 from 160 leaves us 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.

In conclusion, the division gives 13468.47826086 with a balance of 2.2e-08.
