Let's divide 651004 by 80
The aim is to understand the frequency of 80 in 651004.

Let's proceed to step 1:
When dividing 6 by 80, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 80

Moving on to step 2:
80 goes into 65 0 times with 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.
Fetch the next digit (1) from the dividend, attach it to 65 and continue: 651 / 80

On to step 3:
When dividing 651 by 80, we get 8 with a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 11 after subtracting 640 from 651.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 80

Step 4:
110 divided by 80 is 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
If we take 80 away from 110, we end up with 30.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 80

Going ahead to step 5:
If we divide 300 by 80, we get 3 and a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 813.0
If we take 240 away from 300, we end up with 60.
Bring next digit (4) of the dividend behind the 60 and repeat the process: 604 / 80

Going ahead to step 6:
The number 80 fits into 604 7 times, leaving a remainder of 44.
Put 7 as the next digit of the answer. 
Result so far: 8137.0
The remainder is 44 after subtracting 560 from 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
80 goes into 440 5 times with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 8137.5
Subtracting 400 from 440 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.

On to step 8:
400 divided by 80 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 8137.55
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.

The final outcome is 8137.55, with a leftover of 0.0.
