216207 ÷ 23 
The aim is to understand the frequency of 23 in 216207.

On to step 1:
23 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 23

Advancing to step 2:
The number 23 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 23

Advancing to step 3:
When dividing 216 by 23, we get 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 207 away from 216, we end up with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 23

Advancing to step 4:
92 divided by 23 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 94.0
Subtract 92 from 92 to get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 23

Going ahead to step 5:
The number 23 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 940.0
If we subtract 0 from 0, we get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 23

Step 6:
23 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 9400.0
If we take 0 away from 7, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
If we divide 70 by 23, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 9400.3
The remainder is 1 after subtracting 69 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
The number 23 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 9400.3
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
The number 23 fits into 100 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 9400.304
Subtract 92 from 100 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
23 goes into 80 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 9400.3043
Subtract 69 from 80 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
23 can be fit into 110 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 9400.30434
Deduct 92 from 110 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.

Advancing to step 12:
180 divided by 23 is 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 9400.304347
Subtracting 161 from 180 leaves us 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 13:
If we divide 190 by 23, we get 8 and a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 9400.3043478
Subtracting 184 from 190 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
When dividing 60 by 23, we get 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 9400.30434782
If we subtract 46 from 60, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 9400.30434782 with a balance of 1.4e-08.
