We look at the division of 884921 by 80 
The aim is to understand the frequency of 80 in 884921.

Advancing 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
Deduct 0 from 8 and we're left with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 80

Advancing to step 2:
88 divided by 80 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
If we take 80 away from 88, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 80

Going ahead to step 3:
80 goes into 84 1 times with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 4 after subtracting 80 from 84.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 80

Moving on to step 4:
49 divided by 80 is 0 with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
Deduct 0 from 49 and we're left with 49.
Fetch the next digit (2) from the dividend, attach it to 49 and continue: 492 / 80

Advancing to step 5:
The number 80 fits into 492 6 times, leaving a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 1106.0
Deduct 480 from 492 and we're left with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 80

Step 6:
80 goes into 121 1 times with a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 11061.0
Subtracting 80 from 121 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 7:
When dividing 410 by 80, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 11061.5
Subtract 400 from 410 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
If we divide 100 by 80, we get 1 and a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 11061.51
If we subtract 80 from 100, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
The number 80 fits into 200 2 times, leaving a remainder of 40.
The next digit of our result is 2. 
Result so far: 11061.512
Subtract 160 from 200 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.

Let's proceed to step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 11061.5125
Subtracting 400 from 400 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.

Step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11061.5125
If we subtract 0 from 0, 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.

On to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 11061.5125
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.

In conclusion, the division gives 11061.5125 with a balance of 0.0.
