We look at the division of 487648 by 80 
The aim is to understand the frequency of 80 in 487648.

Let's proceed to step 1:
If we divide 4 by 80, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 80

Going ahead to step 2:
48 divided by 80 is 0 with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 48 after subtracting 0 from 48.
Grab the next digit (7) from the dividend, add it to 48, then carry on: 487 / 80

On to step 3:
The number 80 fits into 487 6 times, leaving a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 480 from 487 to get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 80

Step 4:
80 can be fit into 76 0 times, resulting in a remainder of 76.
The next digit of our result is 0. 
Result so far: 60.0
If we take 0 away from 76, we end up with 76.
Bring next digit (4) of the dividend behind the 76 and repeat the process: 764 / 80

On to step 5:
80 can be fit into 764 9 times, resulting in a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 609.0
Subtracting 720 from 764 leaves us with 44.
Append the next digit (8) from the dividend to 44 and continue with: 448 / 80

Moving on to step 6:
80 goes into 448 5 times with a remainder of 48.
The number 5 becomes the next digit in our result. 
Result so far: 6095.0
If we subtract 400 from 448, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 7:
When dividing 480 by 80, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 6095.6
Deduct 480 from 480 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.

Moving on to step 8:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6095.6
If we take 0 away from 0, we end up 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.

Step 9:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 6095.6
Subtracting 0 from 0 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.

After the division, we end up with 6095.6 and a remainder of 0.0.
