We're dividing 72710371 by 23 
The aim is to understand the frequency of 23 in 72710371.

Let's proceed to step 1:
When dividing 7 by 23, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 23

Moving on to step 2:
If we divide 72 by 23, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 69 from 72, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 23

On to step 3:
23 can be fit into 37 1 times, resulting in a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Deduct 23 from 37 and we're left with 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 23

Step 4:
If we divide 141 by 23, we get 6 and a remainder of 3.
The next digit of our result is 6. 
Result so far: 316.0
If we take 138 away from 141, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 23

Moving on to step 5:
30 divided by 23 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 3161.0
If we take 23 away from 30, we end up with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 23

Moving on to step 6:
73 divided by 23 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 31613.0
If we take 69 away from 73, we end up with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 23

On to step 7:
47 divided by 23 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 316132.0
If we subtract 46 from 47, we get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 23

Let's proceed to step 8:
23 goes into 11 0 times with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 3161320.0
If we take 0 away from 11, we end up 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.

Advancing to step 9:
23 can be fit into 110 4 times, resulting in a remainder of 18.
The next digit of our result is 4. 
Result so far: 3161320.4
Subtracting 92 from 110 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
180 divided by 23 is 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 3161320.47
Subtract 161 from 180 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 11:
190 divided by 23 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 3161320.478
The remainder is 6 after subtracting 184 from 190.
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 12:
60 divided by 23 is 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 3161320.4782
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.

Moving on to step 13:
23 can be fit into 140 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 3161320.47826
The remainder is 2 after subtracting 138 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
23 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 3161320.47826
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 15:
If we divide 200 by 23, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 3161320.4782608
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.

Let's proceed to step 16:
23 can be fit into 160 6 times, resulting in a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 3161320.47826086
If we subtract 138 from 160, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 3161320.47826086, with a leftover of 2.2e-08.
