We look at the division of 627742 by 23 
The aim is to understand the frequency of 23 in 627742.

Going ahead to step 1:
The number 23 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 23

Advancing to step 2:
23 goes into 62 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 16 after subtracting 46 from 62.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 23

On to step 3:
The number 23 fits into 167 7 times, leaving a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtracting 161 from 167 leaves us with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 23

Going ahead to step 4:
23 goes into 67 2 times with a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 272.0
The remainder is 21 after subtracting 46 from 67.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 23

On to step 5:
214 divided by 23 is 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 2729.0
Subtracting 207 from 214 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 23

Let's proceed to step 6:
When dividing 72 by 23, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 27293.0
Subtract 69 from 72 to 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.

Going ahead to step 7:
The number 23 fits into 30 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 27293.1
If we subtract 23 from 30, we 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.

On to step 8:
If we divide 70 by 23, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 27293.13
Subtracting 69 from 70 leaves us 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.

Advancing to step 9:
The number 23 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 27293.13
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
When dividing 100 by 23, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 27293.1304
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.

Advancing to step 11:
80 divided by 23 is 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 27293.13043
If we take 69 away from 80, we end up 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.

Advancing to step 12:
When dividing 110 by 23, we get 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 27293.130434
Deduct 92 from 110 and we're left 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.

On to step 13:
The number 23 fits into 180 7 times, leaving a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 27293.1304347
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.

Step 14:
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: 27293.13043478
If we take 184 away from 190, we end up 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.

The final outcome is 27293.13043478, with a leftover of 6e-09.
