We're dividing 618687 by 80 
The aim is to understand the frequency of 80 in 618687.

Moving on to step 1:
When dividing 6 by 80, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 80

Advancing to step 2:
The number 80 fits into 61 0 times, leaving a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Take the next digit (8) from the dividend and append it to 61, then repeat: 618 / 80

On to step 3:
618 divided by 80 is 7 with a remainder of 58.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 560 from 618 to get 58.
Bring next digit (6) of the dividend behind the 58 and repeat the process: 586 / 80

Advancing to step 4:
80 goes into 586 7 times with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
If we take 560 away from 586, we end up with 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 80

Going ahead to step 5:
The number 80 fits into 268 3 times, leaving a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 773.0
If we subtract 240 from 268, we get 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 80

Going ahead to step 6:
If we divide 287 by 80, we get 3 and a remainder of 47.
The next digit of our result is 3. 
Result so far: 7733.0
If we subtract 240 from 287, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 7:
80 can be fit into 470 5 times, resulting in a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 7733.5
Subtracting 400 from 470 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
80 can be fit into 700 8 times, resulting in a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 7733.58
Deduct 640 from 700 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
80 goes into 600 7 times with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 7733.587
If we subtract 560 from 600, 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.

On to step 10:
80 goes into 400 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 7733.5875
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.

Moving on to step 11:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 7733.5875
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.

Going ahead to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7733.5875
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.

The quotient of the division is 7733.5875, and the remainder is 0.0.
