We're dividing 84819693 by 312 
The aim is to understand the frequency of 312 in 84819693.

Going ahead to step 1:
312 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 312

Going ahead to step 2:
When dividing 84 by 312, we get 0 with a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Include the next digit (8) from the dividend after 84, then repeat: 848 / 312

Going ahead to step 3:
If we divide 848 by 312, we get 2 and a remainder of 224.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 624 from 848 and we're left with 224.
Take the next digit (1) from the dividend and append it to 224, then repeat: 2241 / 312

Let's proceed to step 4:
The number 312 fits into 2241 7 times, leaving a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Subtracting 2184 from 2241 leaves us with 57.
Bring next digit (9) of the dividend behind the 57 and repeat the process: 579 / 312

On to step 5:
If we divide 579 by 312, we get 1 and a remainder of 267.
The next digit of our result is 1. 
Result so far: 271.0
The remainder is 267 after subtracting 312 from 579.
Include the next digit (6) from the dividend after 267, then repeat: 2676 / 312

Advancing to step 6:
312 goes into 2676 8 times with a remainder of 180.
Write down 8 as next digit of the result. 
Result so far: 2718.0
Deduct 2496 from 2676 and we're left with 180.
Bring next digit (9) of the dividend behind the 180 and repeat the process: 1809 / 312

Step 7:
312 can be fit into 1809 5 times, resulting in a remainder of 249.
The next digit of our result is 5. 
Result so far: 27185.0
The remainder is 249 after subtracting 1560 from 1809.
Bring next digit (3) of the dividend behind the 249 and repeat the process: 2493 / 312

Advancing to step 8:
The number 312 fits into 2493 7 times, leaving a remainder of 309.
The next digit of our result is 7. 
Result so far: 271857.0
Subtract 2184 from 2493 to get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Going ahead to step 9:
3090 divided by 312 is 9 with a remainder of 282.
The number 9 becomes the next digit in our result. 
Result so far: 271857.9
Subtract 2808 from 3090 to get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Let's proceed to step 10:
The number 312 fits into 2820 9 times, leaving a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 271857.99
Deduct 2808 from 2820 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 271857.99, with a leftover of 0.012.
