371516 ÷ 80 
The aim is to understand the frequency of 80 in 371516.

Going ahead to step 1:
80 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 80

Going ahead to step 2:
37 divided by 80 is 0 with a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Take the next digit (1) from the dividend and append it to 37, then repeat: 371 / 80

Let's proceed to step 3:
80 goes into 371 4 times with a remainder of 51.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 320 from 371, we get 51.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 80

Step 4:
80 goes into 515 6 times with a remainder of 35.
Put 6 as the next digit of the answer. 
Result so far: 46.0
If we subtract 480 from 515, we get 35.
Append the next digit (1) from the dividend to 35 and continue with: 351 / 80

Step 5:
80 goes into 351 4 times with a remainder of 31.
Write down 4 as next digit of the result. 
Result so far: 464.0
The remainder is 31 after subtracting 320 from 351.
Include the next digit (6) from the dividend after 31, then repeat: 316 / 80

Advancing to step 6:
The number 80 fits into 316 3 times, leaving a remainder of 76.
Write down 3 as next digit of the result. 
Result so far: 4643.0
Subtracting 240 from 316 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 7:
80 can be fit into 760 9 times, resulting in a remainder of 40.
The next digit of our result is 9. 
Result so far: 4643.9
Subtract 720 from 760 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 8:
If we divide 400 by 80, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 4643.95
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4643.95
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.

Moving on to step 10:
80 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4643.95
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 4643.95 with a remaining 0.0.
