433378 ÷ 23 
The aim is to understand the frequency of 23 in 433378.

Advancing to step 1:
4 divided by 23 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 23

Step 2:
43 divided by 23 is 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 23 from 43 and we're left with 20.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 23

Going ahead to step 3:
When dividing 203 by 23, we get 8 with a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 184 from 203 to get 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 23

On to step 4:
When dividing 193 by 23, we get 8 with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 188.0
The remainder is 9 after subtracting 184 from 193.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 23

Moving on to step 5:
The number 23 fits into 97 4 times, leaving a remainder of 5.
The next digit of our result is 4. 
Result so far: 1884.0
Subtract 92 from 97 to get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 23

Let's proceed to step 6:
23 goes into 58 2 times with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 18842.0
If we take 46 away from 58, we end up with 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:
23 can be fit into 120 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 18842.5
Subtracting 115 from 120 leaves us with 5.
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:
50 divided by 23 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 18842.52
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.

Going ahead to step 9:
The number 23 fits into 40 1 times, leaving a remainder of 17.
The next digit of our result is 1. 
Result so far: 18842.521
Deduct 23 from 40 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
170 divided by 23 is 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 18842.5217
Subtract 161 from 170 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
23 can be fit into 90 3 times, resulting in a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 18842.52173
Subtract 69 from 90 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 12:
When dividing 210 by 23, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 18842.521739
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.

Going ahead to step 13:
The number 23 fits into 30 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 18842.5217391
Deduct 23 from 30 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
23 can be fit into 70 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 18842.52173913
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 18842.52173913, and the remainder is 1e-09.
