We're dividing 702618 by 80 
The aim is to understand the frequency of 80 in 702618.

Step 1:
80 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 80

On to step 2:
If we divide 70 by 80, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Grab the next digit (2) from the dividend, add it to 70, then carry on: 702 / 80

Moving on to step 3:
If we divide 702 by 80, we get 8 and a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 640 from 702 to get 62.
Include the next digit (6) from the dividend after 62, then repeat: 626 / 80

Advancing to step 4:
The number 80 fits into 626 7 times, leaving a remainder of 66.
The next digit of our result is 7. 
Result so far: 87.0
If we take 560 away from 626, we end up with 66.
Include the next digit (1) from the dividend after 66, then repeat: 661 / 80

Step 5:
661 divided by 80 is 8 with a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 878.0
Deduct 640 from 661 and we're left with 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 80

Advancing to step 6:
80 goes into 218 2 times with a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 8782.0
Subtract 160 from 218 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 7:
80 can be fit into 580 7 times, resulting in a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 8782.7
Subtract 560 from 580 to 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.

Let's proceed to step 8:
80 goes into 200 2 times with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 8782.72
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.

Advancing to step 9:
If we divide 400 by 80, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 8782.725
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.

Step 10:
80 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8782.725
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.

Step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8782.725
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.

The final outcome is 8782.725, with a leftover of 0.0.
