403472 divided by 23 
The aim is to understand the frequency of 23 in 403472.

Moving on to step 1:
When dividing 4 by 23, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 23

Moving on to step 2:
The number 23 fits into 40 1 times, leaving a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 17 after subtracting 23 from 40.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 23

On to step 3:
23 goes into 173 7 times with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 12 after subtracting 161 from 173.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 23

On to step 4:
23 goes into 124 5 times with a remainder of 9.
The next digit of our result is 5. 
Result so far: 175.0
Subtracting 115 from 124 leaves us with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 23

Moving on to step 5:
23 goes into 97 4 times with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 1754.0
Subtract 92 from 97 to get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 23

Let's proceed to step 6:
If we divide 52 by 23, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 17542.0
Subtract 46 from 52 to 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.

Let's proceed to step 7:
When dividing 60 by 23, we get 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 17542.2
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.

Moving on to step 8:
When dividing 140 by 23, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 17542.26
Subtract 138 from 140 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
If we divide 20 by 23, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 17542.26
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.

Let's proceed to step 10:
200 divided by 23 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 17542.2608
Subtract 184 from 200 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
23 can be fit into 160 6 times, resulting in a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 17542.26086
Deduct 138 from 160 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 12:
220 divided by 23 is 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 17542.260869
The remainder is 13 after subtracting 207 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 13:
The number 23 fits into 130 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 17542.2608695
If we subtract 115 from 130, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 14:
The number 23 fits into 150 6 times, leaving a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 17542.26086956
Subtract 138 from 150 to 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.

The quotient of the division is 17542.26086956, and the remainder is 1.2e-08.
