Let's divide 587713 by 80
The aim is to understand the frequency of 80 in 587713.

Going ahead to step 1:
When dividing 5 by 80, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 80

Step 2:
If we divide 58 by 80, we get 0 and a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Bring next digit (7) of the dividend behind the 58 and repeat the process: 587 / 80

Advancing to step 3:
587 divided by 80 is 7 with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 560 away from 587, we end up with 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 80

Advancing to step 4:
If we divide 277 by 80, we get 3 and a remainder of 37.
The next digit of our result is 3. 
Result so far: 73.0
If we subtract 240 from 277, we get 37.
Append the next digit (1) from the dividend to 37 and continue with: 371 / 80

On to step 5:
If we divide 371 by 80, we get 4 and a remainder of 51.
Put 4 as the next digit of the answer. 
Result so far: 734.0
If we take 320 away from 371, we end up with 51.
Take the next digit (3) from the dividend and append it to 51, then repeat: 513 / 80

Advancing to step 6:
If we divide 513 by 80, we get 6 and a remainder of 33.
Use 6 as the next digit of our solution. 
Result so far: 7346.0
If we subtract 480 from 513, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
The number 80 fits into 330 4 times, leaving a remainder of 10.
The next digit of our result is 4. 
Result so far: 7346.4
Deduct 320 from 330 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.

Step 8:
80 goes into 100 1 times with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 7346.41
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.

On to step 9:
80 can be fit into 200 2 times, resulting in a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 7346.412
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.

Step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 7346.4125
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.

On to 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: 7346.4125
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.

Step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7346.4125
Deduct 0 from 0 and we're left 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.

After the division, we end up with 7346.4125 and a remainder of 0.0.
