We divide 650005 by 80
The aim is to understand the frequency of 80 in 650005.

Going ahead to step 1:
If we divide 6 by 80, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 80

Let's proceed to step 2:
The number 80 fits into 65 0 times, leaving a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Include the next digit (0) from the dividend after 65, then repeat: 650 / 80

On to step 3:
80 can be fit into 650 8 times, resulting in a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 640 away from 650, we end up with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 80

Going ahead to step 4:
80 can be fit into 100 1 times, resulting in a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Deduct 80 from 100 and we're left with 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 80

Going ahead to step 5:
200 divided by 80 is 2 with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 812.0
Deduct 160 from 200 and we're left with 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 80

Going ahead to step 6:
80 can be fit into 405 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 8125.0
The remainder is 5 after subtracting 400 from 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
The number 80 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 8125.0
If we take 0 away from 50, we end up 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.

Advancing to step 8:
If we divide 500 by 80, we get 6 and a remainder of 20.
The next digit of our result is 6. 
Result so far: 8125.06
The remainder is 20 after subtracting 480 from 500.
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 9:
80 can be fit into 200 2 times, resulting in a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 8125.062
Subtract 160 from 200 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.

On to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 8125.0625
Subtract 400 from 400 to get 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 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8125.0625
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8125.0625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 8125.0625 with a remainder of 0.0.
