We're dividing 720436 by 23 
The aim is to understand the frequency of 23 in 720436.

Advancing to step 1:
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: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 23

Moving on to step 2:
When dividing 72 by 23, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 3 after subtracting 69 from 72.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 23

Advancing to step 3:
23 goes into 30 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we take 23 away from 30, we end up with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 23

Moving on to step 4:
When dividing 74 by 23, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 313.0
The remainder is 5 after subtracting 69 from 74.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 23

Advancing to step 5:
When dividing 53 by 23, we get 2 with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 3132.0
The remainder is 7 after subtracting 46 from 53.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 23

Moving on to step 6:
23 can be fit into 76 3 times, resulting in a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 31323.0
Subtract 69 from 76 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.

Going ahead to step 7:
The number 23 fits into 70 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 31323.3
If we subtract 69 from 70, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
23 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 31323.3
Deduct 0 from 10 and we're left 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:
If we divide 100 by 23, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 31323.304
If we subtract 92 from 100, 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 10:
23 goes into 80 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 31323.3043
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.

Moving on to step 11:
If we divide 110 by 23, we get 4 and a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 31323.30434
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.

Going ahead to step 12:
When dividing 180 by 23, we get 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 31323.304347
Deduct 161 from 180 and we're left 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:
When dividing 190 by 23, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 31323.3043478
If we subtract 184 from 190, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
The number 23 fits into 60 2 times, leaving a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 31323.30434782
Deduct 46 from 60 and we're left with 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 31323.30434782 with a balance of 1.4e-08.
