We divide 571266 by 80
The aim is to understand the frequency of 80 in 571266.

Advancing to step 1:
If we divide 5 by 80, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 80

On to step 2:
If we divide 57 by 80, we get 0 and a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Bring next digit (1) of the dividend behind the 57 and repeat the process: 571 / 80

Let's proceed to step 3:
80 can be fit into 571 7 times, resulting in a remainder of 11.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 11 after subtracting 560 from 571.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 80

Step 4:
80 goes into 112 1 times with a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
The remainder is 32 after subtracting 80 from 112.
Grab the next digit (6) from the dividend, add it to 32, then carry on: 326 / 80

Going ahead to step 5:
80 goes into 326 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 714.0
If we subtract 320 from 326, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 80

Moving on to step 6:
If we divide 66 by 80, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 7140.0
If we subtract 0 from 66, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 7:
When dividing 660 by 80, we get 8 with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 7140.8
The remainder is 20 after subtracting 640 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
80 goes into 200 2 times with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 7140.82
The remainder is 40 after subtracting 160 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
400 divided by 80 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 7140.825
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: 7140.825
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.

Moving on to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7140.825
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.

Our division results in 7140.825 with a remaining 0.0.
