19484100 divided by 80 
The aim is to understand the frequency of 80 in 19484100.

Moving on 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
Subtracting 0 from 1 leaves us with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 80

Moving on to step 2:
If we divide 19 by 80, we get 0 and a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 80

Advancing to step 3:
80 goes into 194 2 times with a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 160 from 194 to get 34.
Bring next digit (8) of the dividend behind the 34 and repeat the process: 348 / 80

Let's proceed to step 4:
80 can be fit into 348 4 times, resulting in a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we take 320 away from 348, we end up with 28.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 80

Going ahead to step 5:
80 can be fit into 284 3 times, resulting in a remainder of 44.
The number 3 becomes the next digit in our result. 
Result so far: 243.0
Deduct 240 from 284 and we're left with 44.
Bring next digit (1) of the dividend behind the 44 and repeat the process: 441 / 80

Going ahead to step 6:
441 divided by 80 is 5 with a remainder of 41.
Record the quotient 5 as the next digit in the result. 
Result so far: 2435.0
Subtracting 400 from 441 leaves us with 41.
Bring next digit (0) of the dividend behind the 41 and repeat the process: 410 / 80

Let's proceed to step 7:
If we divide 410 by 80, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 24355.0
If we subtract 400 from 410, we get 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 80

Moving on to step 8:
100 divided by 80 is 1 with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 243551.0
The remainder is 20 after subtracting 80 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
200 divided by 80 is 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 243551.2
Subtract 160 from 200 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
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: 243551.25
If we take 400 away from 400, we end up 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.

Advancing to step 11:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 243551.25
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.

Advancing to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 243551.25
If we take 0 away from 0, we end up 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.

The final outcome is 243551.25, with a leftover of 0.0.
