987680 ÷ 80 
The aim is to understand the frequency of 80 in 987680.

Going ahead to step 1:
When dividing 9 by 80, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 80

Let's proceed to step 2:
The number 80 fits into 98 1 times, leaving a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 80 from 98 and we're left with 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 80

On to step 3:
When dividing 187 by 80, we get 2 with a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 160 from 187 leaves us with 27.
Append the next digit (6) from the dividend to 27 and continue with: 276 / 80

Step 4:
The number 80 fits into 276 3 times, leaving a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
Deduct 240 from 276 and we're left with 36.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 80

Advancing to step 5:
80 can be fit into 368 4 times, resulting in a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 1234.0
The remainder is 48 after subtracting 320 from 368.
Bring next digit (0) of the dividend behind the 48 and repeat the process: 480 / 80

On to step 6:
80 goes into 480 6 times with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 12346.0
Subtract 480 from 480 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.

On to step 7:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12346.0
Subtract 0 from 0 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.

Step 8:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12346.0
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.

In conclusion, the division gives 12346.0 with a balance of 0.0.
