We divide 12620 by 23
The aim is to understand the frequency of 23 in 12620.

Step 1:
1 divided by 23 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 23

Moving on to step 2:
23 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 23

Advancing to step 3:
When dividing 126 by 23, we get 5 with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 115 from 126 to get 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 23

Let's proceed to step 4:
When dividing 112 by 23, we get 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
Subtract 92 from 112 to get 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 23

Moving on to step 5:
200 divided by 23 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 548.0
If we subtract 184 from 200, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 6:
23 goes into 160 6 times with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 548.6
If we take 138 away from 160, we end up 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.

Advancing to step 7:
220 divided by 23 is 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 548.69
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.

On to step 8:
The number 23 fits into 130 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 548.695
Deduct 115 from 130 and we're left with 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.
Record the quotient 6 as the next digit in the result. 
Result so far: 548.6956
Deduct 138 from 150 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
23 goes into 120 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 548.69565
The remainder is 5 after subtracting 115 from 120.
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:
23 goes into 50 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 548.695652
Subtracting 46 from 50 leaves us with 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:
When dividing 40 by 23, we get 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 548.6956521
If we subtract 23 from 40, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 13:
170 divided by 23 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 548.69565217
If we subtract 161 from 170, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 548.69565217 with a balance of 9e-09.
