870419 divided by 65 
The aim is to understand the frequency of 65 in 870419.

Let's proceed to step 1:
When dividing 8 by 65, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 65

Moving on to step 2:
87 divided by 65 is 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 65 from 87 leaves us with 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 65

On to step 3:
65 goes into 220 3 times with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 195 from 220 leaves us with 25.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 65

Step 4:
When dividing 254 by 65, we get 3 with a remainder of 59.
The next digit of our result is 3. 
Result so far: 133.0
Subtract 195 from 254 to get 59.
Include the next digit (1) from the dividend after 59, then repeat: 591 / 65

Let's proceed to step 5:
65 goes into 591 9 times with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 1339.0
Deduct 585 from 591 and we're left with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 65

Moving on to step 6:
65 goes into 69 1 times with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 13391.0
If we take 65 away from 69, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
If we divide 40 by 65, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 13391.0
Subtract 0 from 40 to 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.

Advancing to step 8:
65 can be fit into 400 6 times, resulting in a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 13391.06
If we take 390 away from 400, we end up 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.

Step 9:
65 goes into 100 1 times with a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 13391.061
If we subtract 65 from 100, we 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.

On to step 10:
If we divide 350 by 65, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 13391.0615
If we take 325 away from 350, we end up 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.

Let's proceed to step 11:
65 can be fit into 250 3 times, resulting in a remainder of 55.
Record the quotient 3 as the next digit in the result. 
Result so far: 13391.06153
Subtracting 195 from 250 leaves us 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.

Advancing to step 12:
550 divided by 65 is 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 13391.061538
The remainder is 30 after subtracting 520 from 550.
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:
300 divided by 65 is 4 with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 13391.0615384
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.

On to step 14:
65 goes into 400 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 13391.06153846
Deduct 390 from 400 and we're left 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.

The final result is 13391.06153846 with a remainder of 1e-08.
