We look at the division of 820004 by 23 
The aim is to understand the frequency of 23 in 820004.

Going ahead to step 1:
8 divided by 23 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 23

Moving on to step 2:
23 goes into 82 3 times with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 69 from 82 to get 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 23

Let's proceed to step 3:
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: 35.0
The remainder is 15 after subtracting 115 from 130.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 23

Let's proceed to step 4:
If we divide 150 by 23, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 356.0
The remainder is 12 after subtracting 138 from 150.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 23

Advancing to step 5:
120 divided by 23 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 3565.0
The remainder is 5 after subtracting 115 from 120.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 23

Let's proceed to step 6:
23 can be fit into 54 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 35652.0
If we subtract 46 from 54, we 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.

Going ahead to step 7:
The number 23 fits into 80 3 times, leaving a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 35652.3
The remainder is 11 after subtracting 69 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 8:
23 goes into 110 4 times with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 35652.34
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.

Going ahead to step 9:
If we divide 180 by 23, we get 7 and a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 35652.347
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 10:
The number 23 fits into 190 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 35652.3478
If we take 184 away from 190, we end up 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.

Let's proceed to step 11:
If we divide 60 by 23, we get 2 and a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 35652.34782
The remainder is 14 after subtracting 46 from 60.
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 12:
If we divide 140 by 23, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 35652.347826
Deduct 138 from 140 and we're left 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.

Advancing to step 13:
When dividing 20 by 23, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 35652.347826
Deduct 0 from 20 and we're left 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.

Going ahead to step 14:
If we divide 200 by 23, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 35652.34782608
The remainder is 16 after subtracting 184 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 35652.34782608 with a remainder of 1.6e-08.
