165937 divided by 80 
The aim is to understand the frequency of 80 in 165937.

Step 1:
If we divide 1 by 80, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 80

On to step 2:
When dividing 16 by 80, we get 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 80

Moving on to step 3:
80 goes into 165 2 times 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.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 80

Moving on to step 4:
If we divide 59 by 80, we get 0 and a remainder of 59.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 59, we get 59.
Grab the next digit (3) from the dividend, add it to 59, then carry on: 593 / 80

On to step 5:
When dividing 593 by 80, we get 7 with a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 207.0
Subtract 560 from 593 to get 33.
Take the next digit (7) from the dividend and append it to 33, then repeat: 337 / 80

Step 6:
If we divide 337 by 80, we get 4 and a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 2074.0
If we subtract 320 from 337, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
80 goes into 170 2 times with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2074.2
The remainder is 10 after subtracting 160 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
80 can be fit into 100 1 times, resulting in a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 2074.21
If we subtract 80 from 100, we 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.

On to step 9:
If we divide 200 by 80, we get 2 and a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 2074.212
Subtract 160 from 200 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.

Advancing to step 10:
80 goes into 400 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 2074.2125
If we take 400 away from 400, 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.

Let's proceed to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2074.2125
Subtract 0 from 0 to 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 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2074.2125
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.

Our division results in 2074.2125 with a remaining 0.0.
