We look at the division of 142215 by 65 
The aim is to understand the frequency of 65 in 142215.

Going ahead to step 1:
When dividing 1 by 65, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 65

Let's proceed to step 2:
65 goes into 14 0 times with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 65

Advancing to step 3:
142 divided by 65 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 130 from 142, we get 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 65

Advancing to step 4:
65 can be fit into 122 1 times, resulting in a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 65 from 122 to get 57.
Include the next digit (1) from the dividend after 57, then repeat: 571 / 65

Going ahead to step 5:
When dividing 571 by 65, we get 8 with a remainder of 51.
The number 8 becomes the next digit in our result. 
Result so far: 218.0
The remainder is 51 after subtracting 520 from 571.
Append the next digit (5) from the dividend to 51 and continue with: 515 / 65

Let's proceed to step 6:
If we divide 515 by 65, we get 7 and a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 2187.0
If we subtract 455 from 515, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 7:
The number 65 fits into 600 9 times, leaving a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 2187.9
Subtract 585 from 600 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.

Advancing to step 8:
If we divide 150 by 65, we get 2 and a remainder of 20.
The next digit of our result is 2. 
Result so far: 2187.92
If we take 130 away from 150, we end up 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 9:
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: 2187.923
Subtracting 195 from 200 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.

Step 10:
The number 65 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 2187.923
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.

Let's proceed to step 11:
The number 65 fits into 500 7 times, leaving a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 2187.92307
Subtract 455 from 500 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 12:
65 can be fit into 450 6 times, resulting in a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 2187.923076
If we take 390 away from 450, we end up 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.

Advancing to step 13:
600 divided by 65 is 9 with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 2187.9230769
If we take 585 away from 600, we end up 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 14:
150 divided by 65 is 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 2187.92307692
Subtract 130 from 150 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.

The final outcome is 2187.92307692, with a leftover of 2e-08.
