80507127 ÷ 312 
The aim is to understand the frequency of 312 in 80507127.

Moving on to step 1:
8 divided by 312 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 312

On to step 2:
80 divided by 312 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Bring next digit (5) of the dividend behind the 80 and repeat the process: 805 / 312

Going ahead to step 3:
805 divided by 312 is 2 with a remainder of 181.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 624 from 805 and we're left with 181.
Take the next digit (0) from the dividend and append it to 181, then repeat: 1810 / 312

Step 4:
The number 312 fits into 1810 5 times, leaving a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we subtract 1560 from 1810, we get 250.
Include the next digit (7) from the dividend after 250, then repeat: 2507 / 312

Let's proceed to step 5:
The number 312 fits into 2507 8 times, leaving a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 258.0
Subtract 2496 from 2507 to get 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 312

On to step 6:
If we divide 111 by 312, we get 0 and a remainder of 111.
Put 0 as the next digit of the answer. 
Result so far: 2580.0
If we take 0 away from 111, we end up with 111.
Append the next digit (2) from the dividend to 111 and continue with: 1112 / 312

On to step 7:
312 goes into 1112 3 times with a remainder of 176.
Use 3 as the next digit of our solution. 
Result so far: 25803.0
Subtracting 936 from 1112 leaves us with 176.
Fetch the next digit (7) from the dividend, attach it to 176 and continue: 1767 / 312

Moving on to step 8:
When dividing 1767 by 312, we get 5 with a remainder of 207.
Use 5 as the next digit of our solution. 
Result so far: 258035.0
The remainder is 207 after subtracting 1560 from 1767.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Going ahead to step 9:
312 goes into 2070 6 times with a remainder of 198.
Record the quotient 6 as the next digit in the result. 
Result so far: 258035.6
Deduct 1872 from 2070 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Let's proceed to step 10:
If we divide 1980 by 312, we get 6 and a remainder of 108.
Write down 6 as next digit of the result. 
Result so far: 258035.66
The remainder is 108 after subtracting 1872 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

After the division, we end up with 258035.66 and a remainder of 0.108.
