315899 divided by 86 
The aim is to understand the frequency of 86 in 315899.

Advancing to step 1:
86 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 86

Moving on to step 2:
If we divide 31 by 86, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Append the next digit (5) from the dividend to 31 and continue with: 315 / 86

Going ahead to step 3:
The number 86 fits into 315 3 times, leaving a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 258 from 315, we get 57.
Fetch the next digit (8) from the dividend, attach it to 57 and continue: 578 / 86

Going ahead to step 4:
When dividing 578 by 86, we get 6 with a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 36.0
If we take 516 away from 578, we end up with 62.
Take the next digit (9) from the dividend and append it to 62, then repeat: 629 / 86

Moving on to step 5:
When dividing 629 by 86, we get 7 with a remainder of 27.
The next digit of our result is 7. 
Result so far: 367.0
If we subtract 602 from 629, we get 27.
Fetch the next digit (9) from the dividend, attach it to 27 and continue: 279 / 86

On to step 6:
If we divide 279 by 86, we get 3 and a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 3673.0
Subtract 258 from 279 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
210 divided by 86 is 2 with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 3673.2
If we take 172 away from 210, we end up 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.

Moving on to step 8:
86 can be fit into 380 4 times, resulting in a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 3673.24
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
86 goes into 360 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 3673.244
The remainder is 16 after subtracting 344 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 3673.244 with a balance of 0.0016.
