We're dividing 87324608 by 80 
The aim is to understand the frequency of 80 in 87324608.

Going ahead to step 1:
If we divide 8 by 80, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 80

On to step 2:
80 can be fit into 87 1 times, resulting in a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 80 from 87, we get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 80

On to step 3:
73 divided by 80 is 0 with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 73 after subtracting 0 from 73.
Bring next digit (2) of the dividend behind the 73 and repeat the process: 732 / 80

On to step 4:
732 divided by 80 is 9 with a remainder of 12.
The next digit of our result is 9. 
Result so far: 109.0
Subtract 720 from 732 to get 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 80

Going ahead to step 5:
124 divided by 80 is 1 with a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 1091.0
If we take 80 away from 124, we end up with 44.
Grab the next digit (6) from the dividend, add it to 44, then carry on: 446 / 80

Moving on to step 6:
446 divided by 80 is 5 with a remainder of 46.
The number 5 becomes the next digit in our result. 
Result so far: 10915.0
Subtract 400 from 446 to get 46.
Bring next digit (0) of the dividend behind the 46 and repeat the process: 460 / 80

Let's proceed to step 7:
If we divide 460 by 80, we get 5 and a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 109155.0
Subtract 400 from 460 to get 60.
Take the next digit (8) from the dividend and append it to 60, then repeat: 608 / 80

Step 8:
If we divide 608 by 80, we get 7 and a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 1091557.0
Subtracting 560 from 608 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
80 goes into 480 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 1091557.6
If we subtract 480 from 480, 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.

Going ahead to step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1091557.6
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.

On to step 11:
0 divided by 80 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1091557.6
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.

The final result is 1091557.6 with a remainder of 0.0.
