We're dividing 851689 by 65 
The aim is to understand the frequency of 65 in 851689.

Going ahead to step 1:
65 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 65

Going ahead to step 2:
When dividing 85 by 65, we get 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 20 after subtracting 65 from 85.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 65

Advancing to step 3:
65 can be fit into 201 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 195 from 201 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 65

Let's proceed to step 4:
When dividing 66 by 65, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 131.0
Deduct 65 from 66 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 65

Step 5:
The number 65 fits into 18 0 times, leaving a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 1310.0
If we take 0 away from 18, we end up with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 65

Let's proceed to step 6:
The number 65 fits into 189 2 times, leaving a remainder of 59.
The number 2 becomes the next digit in our result. 
Result so far: 13102.0
If we take 130 away from 189, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 7:
The number 65 fits into 590 9 times, leaving a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 13102.9
Deduct 585 from 590 and we're left 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.

Let's proceed to step 8:
When dividing 50 by 65, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 13102.9
Subtracting 0 from 50 leaves us 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.

Step 9:
If we divide 500 by 65, we get 7 and a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 13102.907
Subtracting 455 from 500 leaves us 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.

Advancing to step 10:
If we divide 450 by 65, we get 6 and a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 13102.9076
If we subtract 390 from 450, 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 11:
600 divided by 65 is 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 13102.90769
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 12:
65 goes into 150 2 times with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 13102.907692
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.

Let's proceed to step 13:
The number 65 fits into 200 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 13102.9076923
If we take 195 away from 200, we end up 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.

On to step 14:
65 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 13102.9076923
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 13102.9076923 and a remainder of 5e-08.
