23721163 ÷ 65 
The aim is to understand the frequency of 65 in 23721163.

Going ahead to step 1:
65 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 65

Moving on to step 2:
The number 65 fits into 23 0 times, leaving a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 65

Step 3:
The number 65 fits into 237 3 times, leaving a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 195 from 237 and we're left with 42.
Include the next digit (2) from the dividend after 42, then repeat: 422 / 65

Moving on to step 4:
The number 65 fits into 422 6 times, leaving a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Subtract 390 from 422 to get 32.
Take the next digit (1) from the dividend and append it to 32, then repeat: 321 / 65

Going ahead to step 5:
65 can be fit into 321 4 times, resulting in a remainder of 61.
Use 4 as the next digit of our solution. 
Result so far: 364.0
Deduct 260 from 321 and we're left with 61.
Include the next digit (1) from the dividend after 61, then repeat: 611 / 65

Let's proceed to step 6:
When dividing 611 by 65, we get 9 with a remainder of 26.
The next digit of our result is 9. 
Result so far: 3649.0
Deduct 585 from 611 and we're left with 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 65

Step 7:
When dividing 266 by 65, we get 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 36494.0
If we take 260 away from 266, we end up with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 65

Let's proceed to step 8:
When dividing 63 by 65, we get 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 364940.0
Subtracting 0 from 63 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 9:
If we divide 630 by 65, we get 9 and a remainder of 45.
Put 9 as the next digit of the answer. 
Result so far: 364940.9
Subtracting 585 from 630 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 10:
The number 65 fits into 450 6 times, leaving a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 364940.96
Subtracting 390 from 450 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
65 goes into 600 9 times with a remainder of 15.
The next digit of our result is 9. 
Result so far: 364940.969
Subtracting 585 from 600 leaves us with 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 12:
The number 65 fits into 150 2 times, leaving a remainder of 20.
The next digit of our result is 2. 
Result so far: 364940.9692
If we subtract 130 from 150, 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.

Going ahead to step 13:
If we divide 200 by 65, we get 3 and a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 364940.96923
If we subtract 195 from 200, 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.

Step 14:
If we divide 50 by 65, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 364940.96923
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 15:
The number 65 fits into 500 7 times, leaving a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 364940.9692307
Deduct 455 from 500 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 16:
If we divide 450 by 65, we get 6 and a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 364940.96923076
Subtracting 390 from 450 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 364940.96923076 and a remainder of 6e-08.
