We're dividing 788318 by 80 
The aim is to understand the frequency of 80 in 788318.

Going ahead to step 1:
When dividing 7 by 80, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 80

On to step 2:
78 divided by 80 is 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Bring next digit (8) of the dividend behind the 78 and repeat the process: 788 / 80

Step 3:
The number 80 fits into 788 9 times, leaving a remainder of 68.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 720 from 788 leaves us with 68.
Take the next digit (3) from the dividend and append it to 68, then repeat: 683 / 80

On to step 4:
The number 80 fits into 683 8 times, leaving a remainder of 43.
Write down 8 as next digit of the result. 
Result so far: 98.0
If we take 640 away from 683, we end up with 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 80

Advancing to step 5:
80 goes into 431 5 times with a remainder of 31.
Write down 5 as next digit of the result. 
Result so far: 985.0
Subtract 400 from 431 to get 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 80

Going ahead to step 6:
80 can be fit into 318 3 times, resulting in a remainder of 78.
Write down 3 as next digit of the result. 
Result so far: 9853.0
Deduct 240 from 318 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 7:
If we divide 780 by 80, we get 9 and a remainder of 60.
Write down 9 as next digit of the result. 
Result so far: 9853.9
If we subtract 720 from 780, we 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.

On to step 8:
The number 80 fits into 600 7 times, leaving a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 9853.97
Subtract 560 from 600 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.

Going ahead to step 9:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 9853.975
Deduct 400 from 400 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.

Going ahead to step 10:
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: 9853.975
Subtract 0 from 0 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:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9853.975
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 9853.975 with a remaining 0.0.
