824158 divided by 80 
The aim is to understand the frequency of 80 in 824158.

On to step 1:
The number 80 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 80

On to step 2:
The number 80 fits into 82 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 80 away from 82, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 80

On to step 3:
80 goes into 24 0 times with a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 24 to get 24.
Include the next digit (1) from the dividend after 24, then repeat: 241 / 80

Let's proceed to step 4:
The number 80 fits into 241 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 103.0
Deduct 240 from 241 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 80

Moving on to step 5:
If we divide 15 by 80, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 1030.0
If we subtract 0 from 15, we get 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 80

Let's proceed to step 6:
The number 80 fits into 158 1 times, leaving a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 10301.0
The remainder is 78 after subtracting 80 from 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 7:
80 goes into 780 9 times with a remainder of 60.
Use 9 as the next digit of our solution. 
Result so far: 10301.9
The remainder is 60 after subtracting 720 from 780.
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 8:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 10301.97
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.

Advancing to step 9:
When dividing 400 by 80, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 10301.975
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.

Advancing to step 10:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10301.975
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.

Going ahead to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10301.975
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.

Our division results in 10301.975 with a remaining 0.0.
