286257 ÷ 65 
The aim is to understand the frequency of 65 in 286257.

Going ahead to step 1:
65 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 65

Step 2:
65 can be fit into 28 0 times, resulting in a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Include the next digit (6) from the dividend after 28, then repeat: 286 / 65

Let's proceed to step 3:
286 divided by 65 is 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 260 from 286 to get 26.
Fetch the next digit (2) from the dividend, attach it to 26 and continue: 262 / 65

Moving on to step 4:
65 can be fit into 262 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 44.0
If we take 260 away from 262, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 65

Moving on to step 5:
65 can be fit into 25 0 times, resulting in a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 440.0
Subtracting 0 from 25 leaves us with 25.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 65

Going ahead to step 6:
The number 65 fits into 257 3 times, leaving a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 4403.0
If we take 195 away from 257, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 7:
When dividing 620 by 65, we get 9 with a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 4403.9
Subtracting 585 from 620 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 8:
65 goes into 350 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 4403.95
Subtract 325 from 350 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
The number 65 fits into 250 3 times, leaving a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 4403.953
If we subtract 195 from 250, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 10:
550 divided by 65 is 8 with a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 4403.9538
If we subtract 520 from 550, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
The number 65 fits into 300 4 times, leaving a remainder of 40.
The next digit of our result is 4. 
Result so far: 4403.95384
If we take 260 away from 300, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
400 divided by 65 is 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 4403.953846
If we subtract 390 from 400, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
100 divided by 65 is 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 4403.9538461
Subtract 65 from 100 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 14:
65 goes into 350 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 4403.95384615
Subtracting 325 from 350 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 4403.95384615, and the remainder is 2.5e-08.
