768726 divided by 23 
The aim is to understand the frequency of 23 in 768726.

Step 1:
If we divide 7 by 23, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 23

Let's proceed to step 2:
23 goes into 76 3 times with a remainder of 7.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 7 after subtracting 69 from 76.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 23

Going ahead to step 3:
When dividing 78 by 23, we get 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 33.0
Subtracting 69 from 78 leaves us with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 23

On to step 4:
23 can be fit into 97 4 times, resulting in a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 334.0
Subtracting 92 from 97 leaves us with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 23

On to step 5:
If we divide 52 by 23, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 3342.0
If we take 46 away from 52, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 23

Step 6:
The number 23 fits into 66 2 times, leaving a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 33422.0
If we subtract 46 from 66, we 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 7:
The number 23 fits into 200 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 33422.8
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.

Step 8:
The number 23 fits into 160 6 times, leaving a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 33422.86
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.

On to step 9:
The number 23 fits into 220 9 times, leaving a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 33422.869
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.

Advancing to step 10:
130 divided by 23 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 33422.8695
Subtract 115 from 130 to 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.

Step 11:
150 divided by 23 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 33422.86956
Deduct 138 from 150 and we're left 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.

Moving on to step 12:
When dividing 120 by 23, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 33422.869565
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.

Advancing to step 13:
The number 23 fits into 50 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 33422.8695652
Deduct 46 from 50 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
The number 23 fits into 40 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 33422.86956521
Subtract 23 from 40 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 33422.86956521, with a leftover of 1.7e-08.
