We're dividing 30494078 by 80 
The aim is to understand the frequency of 80 in 30494078.

Let's proceed to step 1:
80 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 80

Going ahead to step 2:
If we divide 30 by 80, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 80

Step 3:
80 goes into 304 3 times with a remainder of 64.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 240 from 304 and we're left with 64.
Fetch the next digit (9) from the dividend, attach it to 64 and continue: 649 / 80

Advancing to step 4:
80 can be fit into 649 8 times, resulting in a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Deduct 640 from 649 and we're left with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 80

Let's proceed to step 5:
When dividing 94 by 80, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 381.0
The remainder is 14 after subtracting 80 from 94.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 80

Moving on to step 6:
If we divide 140 by 80, we get 1 and a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 3811.0
Subtracting 80 from 140 leaves us with 60.
Fetch the next digit (7) from the dividend, attach it to 60 and continue: 607 / 80

Step 7:
80 can be fit into 607 7 times, resulting in a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 38117.0
Subtract 560 from 607 to get 47.
Grab the next digit (8) from the dividend, add it to 47, then carry on: 478 / 80

Step 8:
If we divide 478 by 80, we get 5 and a remainder of 78.
Write down 5 as next digit of the result. 
Result so far: 381175.0
Deduct 400 from 478 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 9:
The number 80 fits into 780 9 times, leaving a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 381175.9
Subtract 720 from 780 to 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.

Moving on to step 10:
If we divide 600 by 80, we get 7 and a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 381175.97
Deduct 560 from 600 and we're left 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.

Going ahead to step 11:
80 goes into 400 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 381175.975
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.

On to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 381175.975
Deduct 0 from 0 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 13:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 381175.975
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.

After the division, we end up with 381175.975 and a remainder of 0.0.
