We're dividing 165602 by 80 
The aim is to understand the frequency of 80 in 165602.

Let's proceed to step 1:
The number 80 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 80

On to step 2:
If we divide 16 by 80, we get 0 and a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 80

Advancing to step 3:
When dividing 165 by 80, we get 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 160 from 165 and we're left with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 80

Advancing to step 4:
If we divide 56 by 80, we get 0 and a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtract 0 from 56 to get 56.
Grab the next digit (0) from the dividend, add it to 56, then carry on: 560 / 80

Let's proceed to step 5:
The number 80 fits into 560 7 times, leaving a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 207.0
If we take 560 away from 560, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 80

Advancing to step 6:
The number 80 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 2070.0
Subtracting 0 from 2 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
The number 80 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 2070.0
Subtracting 0 from 20 leaves us 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.

Moving on to step 8:
80 can be fit into 200 2 times, resulting in a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 2070.02
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 9:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2070.025
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.

Let's proceed 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: 2070.025
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.

Going ahead 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: 2070.025
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.

In conclusion, the division gives 2070.025 with a balance of 0.0.
