125372 ÷ 23 
The aim is to understand the frequency of 23 in 125372.

On to step 1:
If we divide 1 by 23, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 23

Let's proceed to step 2:
23 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 23

On to step 3:
23 can be fit into 125 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 115 from 125 leaves us with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 23

Moving on to step 4:
If we divide 103 by 23, we get 4 and a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
If we subtract 92 from 103, we get 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 23

Moving on to step 5:
23 goes into 117 5 times with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 545.0
Subtract 115 from 117 to get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 23

Step 6:
22 divided by 23 is 0 with a remainder of 22.
The next digit of our result is 0. 
Result so far: 5450.0
If we subtract 0 from 22, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 7:
The number 23 fits into 220 9 times, leaving a remainder of 13.
The next digit of our result is 9. 
Result so far: 5450.9
If we subtract 207 from 220, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 8:
The number 23 fits into 130 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 5450.95
Subtract 115 from 130 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
150 divided by 23 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 5450.956
Subtract 138 from 150 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
When dividing 120 by 23, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 5450.9565
Subtract 115 from 120 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
The number 23 fits into 50 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 5450.95652
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.

Let's proceed to step 12:
23 goes into 40 1 times with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 5450.956521
Deduct 23 from 40 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 13:
23 goes into 170 7 times with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 5450.9565217
Subtracting 161 from 170 leaves us with 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 14:
90 divided by 23 is 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 5450.95652173
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.

The final outcome is 5450.95652173, with a leftover of 2.1e-08.
