86237712 ÷ 305 
The aim is to understand the frequency of 305 in 86237712.

Let's proceed to step 1:
305 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 305

Moving on to step 2:
86 divided by 305 is 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Fetch the next digit (2) from the dividend, attach it to 86 and continue: 862 / 305

Let's proceed to step 3:
If we divide 862 by 305, we get 2 and a remainder of 252.
The next digit of our result is 2. 
Result so far: 2.0
If we take 610 away from 862, we end up with 252.
Append the next digit (3) from the dividend to 252 and continue with: 2523 / 305

Going ahead to step 4:
The number 305 fits into 2523 8 times, leaving a remainder of 83.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Subtracting 2440 from 2523 leaves us with 83.
Append the next digit (7) from the dividend to 83 and continue with: 837 / 305

On to step 5:
When dividing 837 by 305, we get 2 with a remainder of 227.
Use 2 as the next digit of our solution. 
Result so far: 282.0
The remainder is 227 after subtracting 610 from 837.
Grab the next digit (7) from the dividend, add it to 227, then carry on: 2277 / 305

Moving on to step 6:
When dividing 2277 by 305, we get 7 with a remainder of 142.
The number 7 becomes the next digit in our result. 
Result so far: 2827.0
Deduct 2135 from 2277 and we're left with 142.
Take the next digit (1) from the dividend and append it to 142, then repeat: 1421 / 305

Moving on to step 7:
305 can be fit into 1421 4 times, resulting in a remainder of 201.
Use 4 as the next digit of our solution. 
Result so far: 28274.0
Subtracting 1220 from 1421 leaves us with 201.
Append the next digit (2) from the dividend to 201 and continue with: 2012 / 305

Step 8:
The number 305 fits into 2012 6 times, leaving a remainder of 182.
Use 6 as the next digit of our solution. 
Result so far: 282746.0
Subtract 1830 from 2012 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 9:
If we divide 1820 by 305, we get 5 and a remainder of 295.
The number 5 becomes the next digit in our result. 
Result so far: 282746.5
If we take 1525 away from 1820, we end up with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Let's proceed to step 10:
2950 divided by 305 is 9 with a remainder of 205.
Put 9 as the next digit of the answer. 
Result so far: 282746.59
Deduct 2745 from 2950 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 11:
When dividing 2050 by 305, we get 6 with a remainder of 220.
Use 6 as the next digit of our solution. 
Result so far: 282746.596
If we subtract 1830 from 2050, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 12:
If we divide 2200 by 305, we get 7 and a remainder of 65.
The next digit of our result is 7. 
Result so far: 282746.5967
If we subtract 2135 from 2200, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 13:
305 goes into 650 2 times with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 282746.59672
Deduct 610 from 650 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
400 divided by 305 is 1 with a remainder of 95.
The number 1 becomes the next digit in our result. 
Result so far: 282746.596721
Subtract 305 from 400 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 15:
305 can be fit into 950 3 times, resulting in a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 282746.5967213
Subtract 915 from 950 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 16:
305 can be fit into 350 1 times, resulting in a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 282746.59672131
Deduct 305 from 350 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

In conclusion, the division gives 282746.59672131 with a balance of 4.5e-08.
