919239 divided by 23 
The aim is to understand the frequency of 23 in 919239.

On 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
Deduct 0 from 9 and we're left with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 23

Step 2:
91 divided by 23 is 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 22 after subtracting 69 from 91.
Fetch the next digit (9) from the dividend, attach it to 22 and continue: 229 / 23

Going ahead to step 3:
229 divided by 23 is 9 with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we subtract 207 from 229, we get 22.
Grab the next digit (2) from the dividend, add it to 22, then carry on: 222 / 23

Moving on to step 4:
When dividing 222 by 23, we get 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 399.0
Deduct 207 from 222 and we're left with 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 23

Let's proceed to step 5:
23 goes into 153 6 times with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 3996.0
Subtracting 138 from 153 leaves us with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 23

Moving on to step 6:
23 goes into 159 6 times with a remainder of 21.
Put 6 as the next digit of the answer. 
Result so far: 39966.0
Deduct 138 from 159 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
23 goes into 210 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 39966.9
Subtracting 207 from 210 leaves us 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.

Advancing to step 8:
The number 23 fits into 30 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 39966.91
Subtract 23 from 30 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
If we divide 70 by 23, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 39966.913
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.

Going ahead to step 10:
When dividing 10 by 23, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 39966.913
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.

Moving on to step 11:
The number 23 fits into 100 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 39966.91304
If we take 92 away from 100, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
When dividing 80 by 23, we get 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 39966.913043
The remainder is 11 after subtracting 69 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 13:
The number 23 fits into 110 4 times, leaving a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 39966.9130434
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.

Advancing to step 14:
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: 39966.91304347
Deduct 161 from 180 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 39966.91304347 and a remainder of 1.9e-08.
