300812 ÷ 86 
The aim is to understand the frequency of 86 in 300812.

Advancing to step 1:
The number 86 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 86

On to step 2:
86 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 86

Moving on to step 3:
The number 86 fits into 300 3 times, leaving a remainder of 42.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 258 from 300 leaves us with 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 86

On to step 4:
If we divide 428 by 86, we get 4 and a remainder of 84.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Subtracting 344 from 428 leaves us with 84.
Grab the next digit (1) from the dividend, add it to 84, then carry on: 841 / 86

Moving on to step 5:
When dividing 841 by 86, we get 9 with a remainder of 67.
Write down 9 as next digit of the result. 
Result so far: 349.0
If we subtract 774 from 841, we get 67.
Include the next digit (2) from the dividend after 67, then repeat: 672 / 86

Let's proceed to step 6:
86 goes into 672 7 times with a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 3497.0
If we subtract 602 from 672, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 7:
If we divide 700 by 86, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 3497.8
Deduct 688 from 700 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.

Let's proceed to step 8:
When dividing 120 by 86, we get 1 with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 3497.81
If we subtract 86 from 120, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
The number 86 fits into 340 3 times, leaving a remainder of 82.
Use 3 as the next digit of our solution. 
Result so far: 3497.813
Deduct 258 from 340 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 10:
86 can be fit into 820 9 times, resulting in a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 3497.8139
Deduct 774 from 820 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
86 goes into 460 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 3497.81395
The remainder is 30 after subtracting 430 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
86 can be fit into 300 3 times, resulting in a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 3497.813953
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
When dividing 420 by 86, we get 4 with a remainder of 76.
The next digit of our result is 4. 
Result so far: 3497.8139534
If we subtract 344 from 420, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 14:
If we divide 760 by 86, we get 8 and a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 3497.81395348
If we subtract 688 from 760, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

In conclusion, the division gives 3497.81395348 with a balance of 7.2e-08.
