877593 divided by 80 
The aim is to understand the frequency of 80 in 877593.

Moving on to step 1:
80 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 80

On to step 2:
If we divide 87 by 80, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 80 from 87 leaves us with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 80

Let's proceed to step 3:
80 can be fit into 77 0 times, resulting in a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 77 after subtracting 0 from 77.
Fetch the next digit (5) from the dividend, attach it to 77 and continue: 775 / 80

Advancing to step 4:
When dividing 775 by 80, we get 9 with a remainder of 55.
Use 9 as the next digit of our solution. 
Result so far: 109.0
If we subtract 720 from 775, we get 55.
Grab the next digit (9) from the dividend, add it to 55, then carry on: 559 / 80

Step 5:
80 can be fit into 559 6 times, resulting in a remainder of 79.
Use 6 as the next digit of our solution. 
Result so far: 1096.0
If we take 480 away from 559, we end up with 79.
Fetch the next digit (3) from the dividend, attach it to 79 and continue: 793 / 80

Going ahead to step 6:
The number 80 fits into 793 9 times, leaving a remainder of 73.
The next digit of our result is 9. 
Result so far: 10969.0
Subtracting 720 from 793 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 7:
730 divided by 80 is 9 with a remainder of 10.
The next digit of our result is 9. 
Result so far: 10969.9
Deduct 720 from 730 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 80, we get 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 10969.91
Subtracting 80 from 100 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
When dividing 200 by 80, we get 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 10969.912
If we take 160 away from 200, we end up 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 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 10969.9125
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.

Moving on to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10969.9125
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 12:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10969.9125
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.

In conclusion, the division gives 10969.9125 with a balance of 0.0.
