Let's divide 317120 by 86
The aim is to understand the frequency of 86 in 317120.

Step 1:
86 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 86

Let's proceed to step 2:
When dividing 31 by 86, we get 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Append the next digit (7) from the dividend to 31 and continue with: 317 / 86

Let's proceed to step 3:
When dividing 317 by 86, we get 3 with a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 258 from 317, we get 59.
Append the next digit (1) from the dividend to 59 and continue with: 591 / 86

Going ahead to step 4:
The number 86 fits into 591 6 times, leaving a remainder of 75.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Subtracting 516 from 591 leaves us with 75.
Take the next digit (2) from the dividend and append it to 75, then repeat: 752 / 86

Advancing to step 5:
If we divide 752 by 86, we get 8 and a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 368.0
Subtract 688 from 752 to get 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 86

Let's proceed to step 6:
If we divide 640 by 86, we get 7 and a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 3687.0
If we subtract 602 from 640, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
The number 86 fits into 380 4 times, leaving a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 3687.4
If we take 344 away from 380, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
360 divided by 86 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 3687.44
Subtract 344 from 360 to 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.

Our division results in 3687.44 with a remaining 0.016.
