215002 divided by 80 
The aim is to understand the frequency of 80 in 215002.

Moving on to step 1:
80 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 80

Advancing to step 2:
When dividing 21 by 80, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 80

Step 3:
The number 80 fits into 215 2 times, leaving a remainder of 55.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 160 from 215, we get 55.
Grab the next digit (0) from the dividend, add it to 55, then carry on: 550 / 80

Step 4:
If we divide 550 by 80, we get 6 and a remainder of 70.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
If we subtract 480 from 550, we get 70.
Fetch the next digit (0) from the dividend, attach it to 70 and continue: 700 / 80

Let's proceed to step 5:
The number 80 fits into 700 8 times, leaving a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 268.0
If we subtract 640 from 700, we get 60.
Take the next digit (2) from the dividend and append it to 60, then repeat: 602 / 80

Let's proceed to step 6:
When dividing 602 by 80, we get 7 with a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 2687.0
If we take 560 away from 602, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 7:
80 can be fit into 420 5 times, resulting in a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 2687.5
If we take 400 away from 420, we end up 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.

Let's proceed to step 8:
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: 2687.52
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.

Advancing to step 9:
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: 2687.525
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.

Moving on to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2687.525
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.

Advancing to step 11:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2687.525
Deduct 0 from 0 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.

The quotient of the division is 2687.525, and the remainder is 0.0.
