935897 ÷ 80 
The aim is to understand the frequency of 80 in 935897.

Let's proceed to step 1:
The number 80 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 80

Advancing to step 2:
80 can be fit into 93 1 times, resulting in a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 80 from 93 leaves us with 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 80

Moving on to step 3:
80 goes into 135 1 times with a remainder of 55.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 80 from 135 to get 55.
Fetch the next digit (8) from the dividend, attach it to 55 and continue: 558 / 80

Let's proceed to step 4:
When dividing 558 by 80, we get 6 with a remainder of 78.
The next digit of our result is 6. 
Result so far: 116.0
If we subtract 480 from 558, we get 78.
Grab the next digit (9) from the dividend, add it to 78, then carry on: 789 / 80

Moving on to step 5:
If we divide 789 by 80, we get 9 and a remainder of 69.
The next digit of our result is 9. 
Result so far: 1169.0
If we take 720 away from 789, we end up with 69.
Include the next digit (7) from the dividend after 69, then repeat: 697 / 80

On to step 6:
80 can be fit into 697 8 times, resulting in a remainder of 57.
The next digit of our result is 8. 
Result so far: 11698.0
If we take 640 away from 697, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 7:
80 goes into 570 7 times with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 11698.7
The remainder is 10 after subtracting 560 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
When dividing 100 by 80, we get 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 11698.71
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:
If we divide 200 by 80, we get 2 and a remainder of 40.
The next digit of our result is 2. 
Result so far: 11698.712
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.

Let's proceed to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 11698.7125
If we subtract 400 from 400, 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 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11698.7125
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.

Let's proceed to step 12:
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: 11698.7125
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.

After the division, we end up with 11698.7125 and a remainder of 0.0.
