We look at the division of 303277 by 86 
The aim is to understand the frequency of 86 in 303277.

Let's proceed to step 1:
86 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 86

On to step 2:
30 divided by 86 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Fetch the next digit (3) from the dividend, attach it to 30 and continue: 303 / 86

Advancing to step 3:
86 goes into 303 3 times with a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 258 from 303 and we're left with 45.
Grab the next digit (2) from the dividend, add it to 45, then carry on: 452 / 86

Let's proceed to step 4:
If we divide 452 by 86, we get 5 and a remainder of 22.
Put 5 as the next digit of the answer. 
Result so far: 35.0
If we subtract 430 from 452, we get 22.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 86

Moving on to step 5:
86 goes into 227 2 times with a remainder of 55.
The number 2 becomes the next digit in our result. 
Result so far: 352.0
Subtract 172 from 227 to get 55.
Bring next digit (7) of the dividend behind the 55 and repeat the process: 557 / 86

Let's proceed to step 6:
86 goes into 557 6 times with a remainder of 41.
Use 6 as the next digit of our solution. 
Result so far: 3526.0
Deduct 516 from 557 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 7:
When dividing 410 by 86, we get 4 with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 3526.4
The remainder is 66 after subtracting 344 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 8:
When dividing 660 by 86, we get 7 with a remainder of 58.
The next digit of our result is 7. 
Result so far: 3526.47
The remainder is 58 after subtracting 602 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 9:
If we divide 580 by 86, we get 6 and a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 3526.476
If we subtract 516 from 580, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
86 can be fit into 640 7 times, resulting in a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 3526.4767
Deduct 602 from 640 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 11:
When dividing 380 by 86, we get 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 3526.47674
The remainder is 36 after subtracting 344 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
If we divide 360 by 86, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 3526.476744
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 3526.476744, with a leftover of 1.6e-06.
