We're dividing 286385 by 65 
The aim is to understand the frequency of 65 in 286385.

Going ahead to step 1:
When dividing 2 by 65, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 65

On to step 2:
65 goes into 28 0 times with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 65

Advancing to step 3:
When dividing 286 by 65, we get 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 260 from 286 and we're left with 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 65

Moving on to step 4:
65 goes into 263 4 times with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Subtracting 260 from 263 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 65

On to step 5:
65 goes into 38 0 times with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 440.0
Subtract 0 from 38 to get 38.
Grab the next digit (5) from the dividend, add it to 38, then carry on: 385 / 65

Advancing to step 6:
If we divide 385 by 65, we get 5 and a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 4405.0
If we take 325 away from 385, 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.

On to step 7:
600 divided by 65 is 9 with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 4405.9
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.

Moving on to step 8:
150 divided by 65 is 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 4405.92
Subtracting 130 from 150 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.

On to step 9:
When dividing 200 by 65, we get 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 4405.923
Subtract 195 from 200 to 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 10:
The number 65 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 4405.923
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
65 can be fit into 500 7 times, resulting in a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 4405.92307
If we take 455 away from 500, we end up 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.

Moving on to step 12:
When dividing 450 by 65, we get 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 4405.923076
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 13:
The number 65 fits into 600 9 times, leaving a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 4405.9230769
The remainder is 15 after subtracting 585 from 600.
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:
65 goes into 150 2 times with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 4405.92307692
Subtracting 130 from 150 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.

After the division, we end up with 4405.92307692 and a remainder of 2e-08.
