We look at the division of 85109076 by 312 
The aim is to understand the frequency of 312 in 85109076.

Advancing to step 1:
312 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 312

Let's proceed to step 2:
The number 312 fits into 85 0 times, leaving a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Grab the next digit (1) from the dividend, add it to 85, then carry on: 851 / 312

On to step 3:
The number 312 fits into 851 2 times, leaving a remainder of 227.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 624 from 851 to get 227.
Include the next digit (0) from the dividend after 227, then repeat: 2270 / 312

Moving on to step 4:
If we divide 2270 by 312, we get 7 and a remainder of 86.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we subtract 2184 from 2270, we get 86.
Take the next digit (9) from the dividend and append it to 86, then repeat: 869 / 312

Advancing to step 5:
312 can be fit into 869 2 times, resulting in a remainder of 245.
Use 2 as the next digit of our solution. 
Result so far: 272.0
If we take 624 away from 869, we end up with 245.
Bring next digit (0) of the dividend behind the 245 and repeat the process: 2450 / 312

On to step 6:
312 can be fit into 2450 7 times, resulting in a remainder of 266.
Write down 7 as next digit of the result. 
Result so far: 2727.0
Deduct 2184 from 2450 and we're left with 266.
Fetch the next digit (7) from the dividend, attach it to 266 and continue: 2667 / 312

Moving on to step 7:
2667 divided by 312 is 8 with a remainder of 171.
The number 8 becomes the next digit in our result. 
Result so far: 27278.0
If we take 2496 away from 2667, we end up with 171.
Append the next digit (6) from the dividend to 171 and continue with: 1716 / 312

Advancing to step 8:
1716 divided by 312 is 5 with a remainder of 156.
Record the quotient 5 as the next digit in the result. 
Result so far: 272785.0
If we take 1560 away from 1716, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 9:
The number 312 fits into 1560 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 272785.5
The remainder is 0 after subtracting 1560 from 1560.
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 10:
312 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 272785.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
The number 312 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 272785.5
The remainder is 0 after subtracting 0 from 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 final outcome is 272785.5, with a leftover of 0.0.
