268719 ÷ 80 
The aim is to understand the frequency of 80 in 268719.

Step 1:
2 divided by 80 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 80

On to step 2:
The number 80 fits into 26 0 times, leaving a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Take the next digit (8) from the dividend and append it to 26, then repeat: 268 / 80

Advancing to step 3:
80 goes into 268 3 times with a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 240 from 268 to get 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 80

Moving on to step 4:
80 can be fit into 287 3 times, resulting in a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtracting 240 from 287 leaves us with 47.
Append the next digit (1) from the dividend to 47 and continue with: 471 / 80

Advancing to step 5:
If we divide 471 by 80, we get 5 and a remainder of 71.
Write down 5 as next digit of the result. 
Result so far: 335.0
Subtracting 400 from 471 leaves us with 71.
Grab the next digit (9) from the dividend, add it to 71, then carry on: 719 / 80

Step 6:
80 goes into 719 8 times with a remainder of 79.
Record the quotient 8 as the next digit in the result. 
Result so far: 3358.0
Deduct 640 from 719 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 7:
If we divide 790 by 80, we get 9 and a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 3358.9
If we take 720 away from 790, we end up 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.

On to step 8:
When dividing 700 by 80, we get 8 with a remainder of 60.
The next digit of our result is 8. 
Result so far: 3358.98
If we subtract 640 from 700, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
600 divided by 80 is 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 3358.987
Subtract 560 from 600 to 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.

Step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 3358.9875
Deduct 400 from 400 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.

On to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3358.9875
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:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3358.9875
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.

After the division, we end up with 3358.9875 and a remainder of 0.0.
