Let's divide 858757 by 80
The aim is to understand the frequency of 80 in 858757.

Step 1:
When dividing 8 by 80, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 80

On to step 2:
80 can be fit into 85 1 times, resulting in a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 80 away from 85, we end up with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 80

Let's proceed to step 3:
80 can be fit into 58 0 times, resulting in a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 58 and we're left with 58.
Take the next digit (7) from the dividend and append it to 58, then repeat: 587 / 80

Moving on to step 4:
The number 80 fits into 587 7 times, leaving a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
If we subtract 560 from 587, we get 27.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 80

Let's proceed to step 5:
The number 80 fits into 275 3 times, leaving a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 1073.0
If we take 240 away from 275, we end up with 35.
Bring next digit (7) of the dividend behind the 35 and repeat the process: 357 / 80

Going ahead to step 6:
When dividing 357 by 80, we get 4 with a remainder of 37.
The next digit of our result is 4. 
Result so far: 10734.0
Subtracting 320 from 357 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
80 can be fit into 370 4 times, resulting in a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 10734.4
If we take 320 away from 370, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
When dividing 500 by 80, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 10734.46
Deduct 480 from 500 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.

Moving on to step 9:
When dividing 200 by 80, we get 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 10734.462
If we subtract 160 from 200, we 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:
80 goes into 400 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 10734.4625
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.
Record the quotient 0 as the next digit in the result. 
Result so far: 10734.4625
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.

Moving on to 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: 10734.4625
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.

Our division results in 10734.4625 with a remaining 0.0.
