Let's divide 17557247 by 80
The aim is to understand the frequency of 80 in 17557247.

Going ahead to step 1:
When dividing 1 by 80, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 80

Let's proceed to step 2:
If we divide 17 by 80, we get 0 and a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 80

Moving on to step 3:
The number 80 fits into 175 2 times, leaving a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 160 from 175 leaves us with 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 80

Moving on to step 4:
155 divided by 80 is 1 with a remainder of 75.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 80 from 155 to get 75.
Take the next digit (7) from the dividend and append it to 75, then repeat: 757 / 80

Advancing to step 5:
80 can be fit into 757 9 times, resulting in a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 219.0
The remainder is 37 after subtracting 720 from 757.
Include the next digit (2) from the dividend after 37, then repeat: 372 / 80

Advancing to step 6:
372 divided by 80 is 4 with a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 2194.0
If we subtract 320 from 372, we get 52.
Bring next digit (4) of the dividend behind the 52 and repeat the process: 524 / 80

Going ahead to step 7:
80 goes into 524 6 times with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 21946.0
The remainder is 44 after subtracting 480 from 524.
Bring next digit (7) of the dividend behind the 44 and repeat the process: 447 / 80

Let's proceed to step 8:
When dividing 447 by 80, we get 5 with a remainder of 47.
The number 5 becomes the next digit in our result. 
Result so far: 219465.0
Subtracting 400 from 447 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 9:
When dividing 470 by 80, we get 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 219465.5
If we subtract 400 from 470, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
700 divided by 80 is 8 with a remainder of 60.
The next digit of our result is 8. 
Result so far: 219465.58
Subtract 640 from 700 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.

Going ahead to step 11:
When dividing 600 by 80, we get 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 219465.587
If we subtract 560 from 600, we 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.

Going ahead to step 12:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 219465.5875
The remainder is 0 after subtracting 400 from 400.
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 13:
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: 219465.5875
The remainder is 0 after subtracting 0 from 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 14:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 219465.5875
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.

In conclusion, the division gives 219465.5875 with a balance of 0.0.
