We're dividing 659715 by 23 
The aim is to understand the frequency of 23 in 659715.

Advancing to step 1:
23 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 23

Going ahead to step 2:
65 divided by 23 is 2 with a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 46 from 65, we get 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 23

Moving on to step 3:
23 goes into 199 8 times with a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we subtract 184 from 199, we get 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 23

On to step 4:
23 can be fit into 157 6 times, resulting in a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 286.0
If we subtract 138 from 157, we get 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 23

Moving on to step 5:
23 can be fit into 191 8 times, resulting in a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 2868.0
If we take 184 away from 191, we end up with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 23

Step 6:
The number 23 fits into 75 3 times, leaving a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 28683.0
If we subtract 69 from 75, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
The number 23 fits into 60 2 times, leaving a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 28683.2
Subtracting 46 from 60 leaves us 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.

Moving on to step 8:
The number 23 fits into 140 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 28683.26
If we subtract 138 from 140, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
20 divided by 23 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 28683.26
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
The number 23 fits into 200 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 28683.2608
Deduct 184 from 200 and we're left 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.

Going ahead to step 11:
The number 23 fits into 160 6 times, leaving a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 28683.26086
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 12:
If we divide 220 by 23, we get 9 and a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 28683.260869
Subtracting 207 from 220 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 13:
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: 28683.2608695
If we subtract 115 from 130, we 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.

Advancing to step 14:
The number 23 fits into 150 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 28683.26086956
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.

The final result is 28683.26086956 with a remainder of 1.2e-08.
