184987 ÷ 80 
The aim is to understand the frequency of 80 in 184987.

Let's proceed to step 1:
The number 80 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 80

Step 2:
If we divide 18 by 80, we get 0 and a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 80

On to step 3:
If we divide 184 by 80, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 24 after subtracting 160 from 184.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 80

On to step 4:
The number 80 fits into 249 3 times, leaving a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we take 240 away from 249, we end up with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 80

Moving on to step 5:
The number 80 fits into 98 1 times, leaving a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 231.0
If we take 80 away from 98, we end up with 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 80

Going ahead to step 6:
80 can be fit into 187 2 times, resulting in a remainder of 27.
The next digit of our result is 2. 
Result so far: 2312.0
If we take 160 away from 187, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
270 divided by 80 is 3 with a remainder of 30.
The next digit of our result is 3. 
Result so far: 2312.3
If we subtract 240 from 270, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
80 goes into 300 3 times with a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 2312.33
If we subtract 240 from 300, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 2312.33 and a remainder of 0.06.
