We look at the division of 753620 by 23 
The aim is to understand the frequency of 23 in 753620.

Going ahead to step 1:
The number 23 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 23

On to step 2:
75 divided by 23 is 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 69 from 75 and we're left with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 23

Advancing to step 3:
23 can be fit into 63 2 times, resulting in a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Subtract 46 from 63 to get 17.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 23

Step 4:
When dividing 176 by 23, we get 7 with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 327.0
The remainder is 15 after subtracting 161 from 176.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 23

Step 5:
The number 23 fits into 152 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 3276.0
If we subtract 138 from 152, we get 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 23

On to step 6:
23 can be fit into 140 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 32766.0
Deduct 138 from 140 and we're left with 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 7:
If we divide 20 by 23, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 32766.0
Subtracting 0 from 20 leaves us 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.

Going ahead to step 8:
23 can be fit into 200 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 32766.08
If we subtract 184 from 200, we 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.

Going ahead to step 9:
When dividing 160 by 23, we get 6 with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 32766.086
The remainder is 22 after subtracting 138 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
If we divide 220 by 23, we get 9 and a remainder of 13.
The next digit of our result is 9. 
Result so far: 32766.0869
If we take 207 away from 220, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 11:
130 divided by 23 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 32766.08695
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.

On to step 12:
If we divide 150 by 23, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 32766.086956
The remainder is 12 after subtracting 138 from 150.
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 13:
If we divide 120 by 23, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 32766.0869565
If we subtract 115 from 120, we get 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 14:
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: 32766.08695652
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.

The final outcome is 32766.08695652, with a leftover of 4e-09.
