We divide 65169 by 80
The aim is to understand the frequency of 80 in 65169.

Advancing to step 1:
When dividing 6 by 80, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 80

On to step 2:
If we divide 65 by 80, we get 0 and a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Fetch the next digit (1) from the dividend, attach it to 65 and continue: 651 / 80

Let's proceed to step 3:
651 divided by 80 is 8 with a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 640 from 651 leaves us with 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 80

Moving on to step 4:
80 can be fit into 116 1 times, resulting in a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 81.0
If we subtract 80 from 116, we get 36.
Take the next digit (9) from the dividend and append it to 36, then repeat: 369 / 80

Step 5:
369 divided by 80 is 4 with a remainder of 49.
Put 4 as the next digit of the answer. 
Result so far: 814.0
The remainder is 49 after subtracting 320 from 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 6:
80 goes into 490 6 times with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 814.6
The remainder is 10 after subtracting 480 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
If we divide 100 by 80, we get 1 and a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 814.61
Subtract 80 from 100 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
If we divide 200 by 80, we get 2 and a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 814.612
Subtracting 160 from 200 leaves us 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.

Let's proceed to step 9:
80 goes into 400 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 814.6125
Subtracting 400 from 400 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 814.6125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 814.6125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 814.6125 with a remaining 0.0.
