Let's divide 454121 by 80
The aim is to understand the frequency of 80 in 454121.

Step 1:
80 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 80

Moving on to step 2:
45 divided by 80 is 0 with a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 80

Advancing to step 3:
454 divided by 80 is 5 with a remainder of 54.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 400 from 454 and we're left with 54.
Bring next digit (1) of the dividend behind the 54 and repeat the process: 541 / 80

Going ahead to step 4:
80 goes into 541 6 times with a remainder of 61.
The next digit of our result is 6. 
Result so far: 56.0
Deduct 480 from 541 and we're left with 61.
Append the next digit (2) from the dividend to 61 and continue with: 612 / 80

Let's proceed to step 5:
612 divided by 80 is 7 with a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 567.0
If we subtract 560 from 612, we get 52.
Take the next digit (1) from the dividend and append it to 52, then repeat: 521 / 80

Let's proceed to step 6:
521 divided by 80 is 6 with a remainder of 41.
The next digit of our result is 6. 
Result so far: 5676.0
If we subtract 480 from 521, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 7:
The number 80 fits into 410 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 5676.5
Subtracting 400 from 410 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 80 fits into 100 1 times, leaving a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 5676.51
Deduct 80 from 100 and we're left 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 9:
80 goes into 200 2 times with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 5676.512
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:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5676.5125
Subtract 400 from 400 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.

Let's proceed to step 11:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5676.5125
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.

Let's proceed to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5676.5125
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.

After the division, we end up with 5676.5125 and a remainder of 0.0.
