Let's divide 618971 by 23
The aim is to understand the frequency of 23 in 618971.

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
The remainder is 6 after subtracting 0 from 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 23

Let's proceed to step 2:
When dividing 61 by 23, we get 2 with a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 46 from 61, we get 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 23

Let's proceed to step 3:
The number 23 fits into 158 6 times, leaving a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Subtract 138 from 158 to get 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 23

Let's proceed to step 4:
If we divide 209 by 23, we get 9 and a remainder of 2.
The next digit of our result is 9. 
Result so far: 269.0
Subtracting 207 from 209 leaves us with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 23

Let's proceed to step 5:
23 goes into 27 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 2691.0
Subtracting 23 from 27 leaves us with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 23

Advancing to step 6:
23 goes into 41 1 times with a remainder of 18.
The next digit of our result is 1. 
Result so far: 26911.0
Deduct 23 from 41 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.

Moving on to step 7:
180 divided by 23 is 7 with a remainder of 19.
The next digit of our result is 7. 
Result so far: 26911.7
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.

Step 8:
The number 23 fits into 190 8 times, leaving a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 26911.78
The remainder is 6 after subtracting 184 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
23 goes into 60 2 times with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 26911.782
Deduct 46 from 60 and we're left 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.

Advancing to step 10:
140 divided by 23 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 26911.7826
If we take 138 away from 140, we end up 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.

Let's proceed to step 11:
23 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 26911.7826
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
23 can be fit into 200 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 26911.782608
Subtracting 184 from 200 leaves us 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.

Step 13:
The number 23 fits into 160 6 times, leaving a remainder of 22.
The next digit of our result is 6. 
Result so far: 26911.7826086
Subtract 138 from 160 to 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 14:
23 goes into 220 9 times with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 26911.78260869
Subtract 207 from 220 to 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.

In conclusion, the division gives 26911.78260869 with a balance of 1.3e-08.
