666118 divided by 23 
The aim is to understand the frequency of 23 in 666118.

Advancing to step 1:
6 divided by 23 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 23

Advancing to step 2:
23 goes into 66 2 times with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 20 after subtracting 46 from 66.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 23

Moving on to step 3:
23 can be fit into 206 8 times, resulting in a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Subtract 184 from 206 to get 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 23

Advancing to step 4:
23 can be fit into 221 9 times, resulting in a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 289.0
The remainder is 14 after subtracting 207 from 221.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 23

Step 5:
If we divide 141 by 23, we get 6 and a remainder of 3.
The next digit of our result is 6. 
Result so far: 2896.0
Deduct 138 from 141 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 23

Step 6:
23 goes into 38 1 times with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 28961.0
If we take 23 away from 38, we end up 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.

Step 7:
When dividing 150 by 23, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 28961.6
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.

Going ahead to step 8:
The number 23 fits into 120 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 28961.65
Subtracting 115 from 120 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
The number 23 fits into 50 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 28961.652
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.

On to step 10:
The number 23 fits into 40 1 times, leaving a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 28961.6521
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 11:
When dividing 170 by 23, we get 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 28961.65217
Deduct 161 from 170 and we're left 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.

Let's proceed to step 12:
23 can be fit into 90 3 times, resulting in a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 28961.652173
Deduct 69 from 90 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 13:
If we divide 210 by 23, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 28961.6521739
Subtracting 207 from 210 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 14:
30 divided by 23 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 28961.65217391
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.

Our division results in 28961.65217391 with a remaining 7e-09.
