Let's divide 891962 by 80
The aim is to understand the frequency of 80 in 891962.

Advancing to step 1:
When dividing 8 by 80, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 80

Let's proceed to step 2:
If we divide 89 by 80, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 80 from 89 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 80

On to step 3:
If we divide 91 by 80, we get 1 and a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 11 after subtracting 80 from 91.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 80

Going ahead to step 4:
The number 80 fits into 119 1 times, leaving a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 111.0
Deduct 80 from 119 and we're left with 39.
Fetch the next digit (6) from the dividend, attach it to 39 and continue: 396 / 80

On to step 5:
80 can be fit into 396 4 times, resulting in a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 1114.0
Subtracting 320 from 396 leaves us with 76.
Include the next digit (2) from the dividend after 76, then repeat: 762 / 80

Step 6:
762 divided by 80 is 9 with a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 11149.0
Deduct 720 from 762 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 7:
The number 80 fits into 420 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 11149.5
Deduct 400 from 420 and we're left 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 8:
If we divide 200 by 80, we get 2 and a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 11149.52
Deduct 160 from 200 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.

On 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: 11149.525
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 10:
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: 11149.525
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.

Step 11:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11149.525
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 11149.525 with a remaining 0.0.
