We look at the division of 314175 by 80 
The aim is to understand the frequency of 80 in 314175.

Going ahead to step 1:
3 divided by 80 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 80

Moving on to step 2:
If we divide 31 by 80, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (4) from the dividend, add it to 31, then carry on: 314 / 80

Going ahead to step 3:
314 divided by 80 is 3 with a remainder of 74.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 74 after subtracting 240 from 314.
Bring next digit (1) of the dividend behind the 74 and repeat the process: 741 / 80

On to step 4:
If we divide 741 by 80, we get 9 and a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
The remainder is 21 after subtracting 720 from 741.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 80

Let's proceed to step 5:
80 can be fit into 217 2 times, resulting in a remainder of 57.
Write down 2 as next digit of the result. 
Result so far: 392.0
If we subtract 160 from 217, we get 57.
Bring next digit (5) of the dividend behind the 57 and repeat the process: 575 / 80

Let's proceed to step 6:
If we divide 575 by 80, we get 7 and a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 3927.0
Subtract 560 from 575 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
If we divide 150 by 80, we get 1 and a remainder of 70.
Record the quotient 1 as the next digit in the result. 
Result so far: 3927.1
If we take 80 away from 150, 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:
80 goes into 700 8 times with a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 3927.18
Subtract 640 from 700 to 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.

Moving on to step 9:
When dividing 600 by 80, we get 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 3927.187
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.

Going ahead 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: 3927.1875
Subtract 400 from 400 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.

Advancing to step 11:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3927.1875
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.

Advancing to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3927.1875
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.

The quotient of the division is 3927.1875, and the remainder is 0.0.
