Let's divide 8228535 by 23
The aim is to understand the frequency of 23 in 8228535.

On to step 1:
The number 23 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 23

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.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 23

Going ahead to step 3:
The number 23 fits into 132 5 times, leaving a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 35.0
If we subtract 115 from 132, we get 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 23

Going ahead to step 4:
23 goes into 178 7 times with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 357.0
If we take 161 away from 178, we end up with 17.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 23

On to step 5:
When dividing 175 by 23, we get 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 3577.0
Subtract 161 from 175 to get 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 23

Going ahead to step 6:
143 divided by 23 is 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 35776.0
If we subtract 138 from 143, we get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 23

Step 7:
If we divide 55 by 23, we get 2 and a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 357762.0
The remainder is 9 after subtracting 46 from 55.
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 8:
If we divide 90 by 23, we get 3 and a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 357762.3
If we take 69 away from 90, we end up 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.

Step 9:
When dividing 210 by 23, we get 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 357762.39
Subtract 207 from 210 to get 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 10:
The number 23 fits into 30 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 357762.391
Subtract 23 from 30 to 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.

On to step 11:
70 divided by 23 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 357762.3913
Subtracting 69 from 70 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 12:
The number 23 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 357762.3913
Subtracting 0 from 10 leaves us 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.

Advancing to step 13:
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: 357762.391304
Deduct 92 from 100 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
23 goes into 80 3 times with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 357762.3913043
Deduct 69 from 80 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 15:
110 divided by 23 is 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 357762.39130434
If we subtract 92 from 110, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 357762.39130434, and the remainder is 1.8e-08.
