389681 ÷ 23 
The aim is to understand the frequency of 23 in 389681.

Let's proceed to step 1:
23 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 23

Advancing to step 2:
38 divided by 23 is 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 23 from 38 leaves us with 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 23

Going ahead to step 3:
159 divided by 23 is 6 with a remainder of 21.
The next digit of our result is 6. 
Result so far: 16.0
If we take 138 away from 159, we end up with 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 23

On to step 4:
216 divided by 23 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 169.0
Deduct 207 from 216 and we're left with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 23

Let's proceed to step 5:
23 can be fit into 98 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 1694.0
The remainder is 6 after subtracting 92 from 98.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 23

Advancing to step 6:
If we divide 61 by 23, we get 2 and a remainder of 15.
The next digit of our result is 2. 
Result so far: 16942.0
If we take 46 away from 61, 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.

On to step 7:
The number 23 fits into 150 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 16942.6
The remainder is 12 after subtracting 138 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
23 goes into 120 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 16942.65
Subtract 115 from 120 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
The number 23 fits into 50 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 16942.652
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.

Moving on to step 10:
23 can be fit into 40 1 times, resulting in a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 16942.6521
The remainder is 17 after subtracting 23 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 11:
23 goes into 170 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 16942.65217
Subtracting 161 from 170 leaves us 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.

Going ahead to step 12:
The number 23 fits into 90 3 times, leaving a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 16942.652173
Subtract 69 from 90 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead 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: 16942.6521739
Deduct 207 from 210 and we're left 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.

Step 14:
The number 23 fits into 30 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 16942.65217391
The remainder is 7 after subtracting 23 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 16942.65217391 and a remainder of 7e-09.
