We look at the division of 280141 by 65 
The aim is to understand the frequency of 65 in 280141.

Moving on 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
If we take 0 away from 2, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 65

Going ahead to step 2:
When dividing 28 by 65, we get 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Bring next digit (0) of the dividend behind the 28 and repeat the process: 280 / 65

On to step 3:
65 can be fit into 280 4 times, resulting in a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 20 after subtracting 260 from 280.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 65

Advancing to step 4:
65 goes into 201 3 times with a remainder of 6.
The next digit of our result is 3. 
Result so far: 43.0
Subtract 195 from 201 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 65

On to step 5:
65 can be fit into 64 0 times, resulting in a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 430.0
If we subtract 0 from 64, we get 64.
Fetch the next digit (1) from the dividend, attach it to 64 and continue: 641 / 65

Let's proceed to step 6:
65 goes into 641 9 times with a remainder of 56.
The number 9 becomes the next digit in our result. 
Result so far: 4309.0
The remainder is 56 after subtracting 585 from 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 7:
When dividing 560 by 65, we get 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 4309.8
If we subtract 520 from 560, we get 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 8:
If we divide 400 by 65, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 4309.86
Subtracting 390 from 400 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
65 goes into 100 1 times with a remainder of 35.
The next digit of our result is 1. 
Result so far: 4309.861
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.

Let's proceed to step 10:
The number 65 fits into 350 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 4309.8615
The remainder is 25 after subtracting 325 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 11:
When dividing 250 by 65, we get 3 with a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 4309.86153
If we take 195 away from 250, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 12:
65 goes into 550 8 times with a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 4309.861538
If we take 520 away from 550, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
When dividing 300 by 65, we get 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 4309.8615384
Deduct 260 from 300 and we're left 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 14:
The number 65 fits into 400 6 times, leaving a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 4309.86153846
Subtract 390 from 400 to 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.

After the division, we end up with 4309.86153846 and a remainder of 1e-08.
