We're dividing 760581 by 80 
The aim is to understand the frequency of 80 in 760581.

Step 1:
7 divided by 80 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 80

On to step 2:
When dividing 76 by 80, we get 0 with a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Fetch the next digit (0) from the dividend, attach it to 76 and continue: 760 / 80

Going ahead to step 3:
The number 80 fits into 760 9 times, leaving a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 720 from 760, we get 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 80

Going ahead to step 4:
80 goes into 405 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 95.0
If we subtract 400 from 405, we get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 80

Step 5:
If we divide 58 by 80, we get 0 and a remainder of 58.
The next digit of our result is 0. 
Result so far: 950.0
The remainder is 58 after subtracting 0 from 58.
Include the next digit (1) from the dividend after 58, then repeat: 581 / 80

Advancing to step 6:
The number 80 fits into 581 7 times, leaving a remainder of 21.
The next digit of our result is 7. 
Result so far: 9507.0
If we take 560 away from 581, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
80 goes into 210 2 times with a remainder of 50.
The next digit of our result is 2. 
Result so far: 9507.2
Deduct 160 from 210 and we're left 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.

Going ahead to step 8:
500 divided by 80 is 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 9507.26
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.

Going ahead to step 9:
The number 80 fits into 200 2 times, leaving a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 9507.262
Subtracting 160 from 200 leaves us 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.
The number 5 becomes the next digit in our result. 
Result so far: 9507.2625
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.

Going ahead to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9507.2625
Subtract 0 from 0 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.

Advancing to step 12:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9507.2625
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.

Our division results in 9507.2625 with a remaining 0.0.
