We divide 386109 by 86
The aim is to understand the frequency of 86 in 386109.

Going ahead to step 1:
86 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 86

Let's proceed to step 2:
The number 86 fits into 38 0 times, leaving a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 86

On to step 3:
If we divide 386 by 86, we get 4 and a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 344 from 386 leaves us with 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 86

Moving on to step 4:
86 can be fit into 421 4 times, resulting in a remainder of 77.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
If we subtract 344 from 421, we get 77.
Take the next digit (0) from the dividend and append it to 77, then repeat: 770 / 86

Advancing to step 5:
The number 86 fits into 770 8 times, leaving a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 448.0
Deduct 688 from 770 and we're left with 82.
Fetch the next digit (9) from the dividend, attach it to 82 and continue: 829 / 86

Going ahead to step 6:
If we divide 829 by 86, we get 9 and a remainder of 55.
The next digit of our result is 9. 
Result so far: 4489.0
Deduct 774 from 829 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 7:
86 goes into 550 6 times with a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 4489.6
Deduct 516 from 550 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
If we divide 340 by 86, we get 3 and a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 4489.63
Deduct 258 from 340 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 9:
86 can be fit into 820 9 times, resulting in a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 4489.639
Subtract 774 from 820 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 10:
460 divided by 86 is 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 4489.6395
Subtracting 430 from 460 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
86 can be fit into 300 3 times, resulting in a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 4489.63953
If we take 258 away from 300, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
When dividing 420 by 86, we get 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 4489.639534
If we take 344 away from 420, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 13:
86 can be fit into 760 8 times, resulting in a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 4489.6395348
Subtracting 688 from 760 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 14:
86 can be fit into 720 8 times, resulting in a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 4489.63953488
Deduct 688 from 720 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 4489.63953488 with a balance of 3.2e-08.
