Let's divide 320974 by 80
The aim is to understand the frequency of 80 in 320974.

Advancing to step 1:
If we divide 3 by 80, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 80

On to step 2:
32 divided by 80 is 0 with a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 32, we end up with 32.
Include the next digit (0) from the dividend after 32, then repeat: 320 / 80

On to step 3:
80 can be fit into 320 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 0 after subtracting 320 from 320.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 80

Let's proceed to step 4:
80 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 40.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 80

Going ahead to step 5:
If we divide 97 by 80, we get 1 and a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 401.0
The remainder is 17 after subtracting 80 from 97.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 80

Moving on to step 6:
If we divide 174 by 80, we get 2 and a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 4012.0
Subtract 160 from 174 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
If we divide 140 by 80, we get 1 and a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 4012.1
The remainder is 60 after subtracting 80 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
If we divide 600 by 80, we get 7 and a remainder of 40.
The next digit of our result is 7. 
Result so far: 4012.17
If we take 560 away from 600, we end up 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.

Moving on to step 9:
If we divide 400 by 80, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 4012.175
If we subtract 400 from 400, we 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.

Advancing to step 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 4012.175
If we subtract 0 from 0, we 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 11:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4012.175
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 4012.175 and a remainder of 0.0.
