778745 ÷ 23 
The aim is to understand the frequency of 23 in 778745.

Let's proceed to step 1:
When dividing 7 by 23, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 23

On to step 2:
When dividing 77 by 23, we get 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 69 from 77, we get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 23

Advancing to step 3:
If we divide 88 by 23, we get 3 and a remainder of 19.
The next digit of our result is 3. 
Result so far: 33.0
The remainder is 19 after subtracting 69 from 88.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 23

Moving on to step 4:
197 divided by 23 is 8 with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 338.0
Subtract 184 from 197 to get 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 23

Advancing to step 5:
134 divided by 23 is 5 with a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 3385.0
Subtracting 115 from 134 leaves us with 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 23

Step 6:
195 divided by 23 is 8 with a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 33858.0
Subtracting 184 from 195 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
110 divided by 23 is 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 33858.4
Subtract 92 from 110 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
If we divide 180 by 23, we get 7 and a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 33858.47
The remainder is 19 after subtracting 161 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
When dividing 190 by 23, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 33858.478
If we take 184 away from 190, we end up with 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 10:
23 can be fit into 60 2 times, resulting in a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 33858.4782
If we subtract 46 from 60, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
If we divide 140 by 23, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 33858.47826
If we subtract 138 from 140, we 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.

Step 12:
20 divided by 23 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 33858.47826
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
When dividing 200 by 23, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 33858.4782608
If we take 184 away from 200, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
23 can be fit into 160 6 times, resulting in a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 33858.47826086
Subtracting 138 from 160 leaves us 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.

After the division, we end up with 33858.47826086 and a remainder of 2.2e-08.
