968498 ÷ 80 
The aim is to understand the frequency of 80 in 968498.

Step 1:
9 divided by 80 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 80

Let's proceed to step 2:
80 can be fit into 96 1 times, resulting in a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 80 from 96 to get 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 80

Step 3:
When dividing 168 by 80, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 8 after subtracting 160 from 168.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 80

Let's proceed to step 4:
84 divided by 80 is 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 121.0
The remainder is 4 after subtracting 80 from 84.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 80

Going ahead to step 5:
80 can be fit into 49 0 times, resulting in a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 1210.0
The remainder is 49 after subtracting 0 from 49.
Fetch the next digit (8) from the dividend, attach it to 49 and continue: 498 / 80

Step 6:
If we divide 498 by 80, we get 6 and a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 12106.0
Deduct 480 from 498 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
If we divide 180 by 80, we get 2 and a remainder of 20.
The next digit of our result is 2. 
Result so far: 12106.2
If we take 160 away from 180, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
200 divided by 80 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 12106.22
The remainder is 40 after subtracting 160 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 12106.22 with a remaining 0.04.
