We divide 319791 by 86
The aim is to understand the frequency of 86 in 319791.

On to step 1:
The number 86 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 86

Moving on to step 2:
31 divided by 86 is 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 86

Moving on to step 3:
The number 86 fits into 319 3 times, leaving a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 258 from 319, we get 61.
Fetch the next digit (7) from the dividend, attach it to 61 and continue: 617 / 86

Step 4:
86 can be fit into 617 7 times, resulting in a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 37.0
If we subtract 602 from 617, we get 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 86

Step 5:
If we divide 159 by 86, we get 1 and a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 371.0
Deduct 86 from 159 and we're left with 73.
Bring next digit (1) of the dividend behind the 73 and repeat the process: 731 / 86

Step 6:
731 divided by 86 is 8 with a remainder of 43.
Put 8 as the next digit of the answer. 
Result so far: 3718.0
Subtract 688 from 731 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
When dividing 430 by 86, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 3718.5
Deduct 430 from 430 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 86, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3718.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
86 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3718.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 3718.5 with a balance of 0.0.
