216713 ÷ 80 
The aim is to understand the frequency of 80 in 216713.

Advancing to step 1:
2 divided by 80 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 80

On to step 2:
When dividing 21 by 80, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 80

Moving on to step 3:
80 can be fit into 216 2 times, resulting in a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 160 from 216 leaves us with 56.
Bring next digit (7) of the dividend behind the 56 and repeat the process: 567 / 80

Step 4:
The number 80 fits into 567 7 times, leaving a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Deduct 560 from 567 and we're left with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 80

Step 5:
80 goes into 71 0 times with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 270.0
Subtracting 0 from 71 leaves us with 71.
Fetch the next digit (3) from the dividend, attach it to 71 and continue: 713 / 80

On to step 6:
80 can be fit into 713 8 times, resulting in a remainder of 73.
Use 8 as the next digit of our solution. 
Result so far: 2708.0
If we take 640 away from 713, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 7:
80 goes into 730 9 times with a remainder of 10.
The next digit of our result is 9. 
Result so far: 2708.9
The remainder is 10 after subtracting 720 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
80 goes into 100 1 times with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 2708.91
Subtract 80 from 100 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.

Moving on to step 9:
If we divide 200 by 80, we get 2 and a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 2708.912
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.

Moving on to step 10:
400 divided by 80 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2708.9125
Subtracting 400 from 400 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.

Advancing to step 11:
80 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2708.9125
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.
Record the quotient 0 as the next digit in the result. 
Result so far: 2708.9125
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.

Our division results in 2708.9125 with a remaining 0.0.
