We're dividing 802436 by 23 
The aim is to understand the frequency of 23 in 802436.

Moving on to step 1:
23 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 23

Moving on to step 2:
80 divided by 23 is 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 69 from 80, we get 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 23

Moving on to step 3:
If we divide 112 by 23, we get 4 and a remainder of 20.
The next digit of our result is 4. 
Result so far: 34.0
Deduct 92 from 112 and we're left with 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 23

Moving on to step 4:
204 divided by 23 is 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 348.0
The remainder is 20 after subtracting 184 from 204.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 23

Going ahead to step 5:
203 divided by 23 is 8 with a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 3488.0
Deduct 184 from 203 and we're left with 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 23

Advancing to step 6:
23 goes into 196 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 34888.0
If we subtract 184 from 196, we 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.

Let's proceed to step 7:
If we divide 120 by 23, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 34888.5
The remainder is 5 after subtracting 115 from 120.
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 8:
When dividing 50 by 23, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 34888.52
The remainder is 4 after subtracting 46 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
23 can be fit into 40 1 times, resulting in a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 34888.521
Subtract 23 from 40 to 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.

Step 10:
23 goes into 170 7 times with a remainder of 9.
The next digit of our result is 7. 
Result so far: 34888.5217
If we take 161 away from 170, we end up 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.

Advancing to step 11:
23 goes into 90 3 times with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 34888.52173
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.

Going ahead to step 12:
If we divide 210 by 23, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 34888.521739
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.

Step 13:
When dividing 30 by 23, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 34888.5217391
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.

On to step 14:
23 can be fit into 70 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 34888.52173913
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.

The quotient of the division is 34888.52173913, and the remainder is 1e-09.
