802970 ÷ 23 
The aim is to understand the frequency of 23 in 802970.

Step 1:
When dividing 8 by 23, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 23

Let's proceed to step 2:
80 divided by 23 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 69 from 80 leaves us with 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 23

Let's proceed to step 3:
When dividing 112 by 23, we get 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
The remainder is 20 after subtracting 92 from 112.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 23

Moving on to step 4:
When dividing 209 by 23, we get 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 349.0
Subtract 207 from 209 to get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 23

Step 5:
23 can be fit into 27 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 3491.0
The remainder is 4 after subtracting 23 from 27.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 23

Step 6:
40 divided by 23 is 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 34911.0
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.

Moving on to step 7:
When dividing 170 by 23, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 34911.7
If we subtract 161 from 170, we 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.

Let's proceed to step 8:
The number 23 fits into 90 3 times, leaving a remainder of 21.
The next digit of our result is 3. 
Result so far: 34911.73
If we subtract 69 from 90, we 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.

Going ahead to step 9:
23 goes into 210 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 34911.739
The remainder is 3 after subtracting 207 from 210.
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:
23 goes into 30 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 34911.7391
If we subtract 23 from 30, we 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.

Step 11:
23 goes into 70 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 34911.73913
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.

Step 12:
23 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 34911.73913
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
23 can be fit into 100 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 34911.7391304
Subtracting 92 from 100 leaves us 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.

Let's proceed to step 14:
When dividing 80 by 23, we get 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 34911.73913043
If we subtract 69 from 80, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 34911.73913043 with a remaining 1.1e-08.
