130571 divided by 86 
The aim is to understand the frequency of 86 in 130571.

Going ahead to step 1:
86 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 86

Advancing to step 2:
86 can be fit into 13 0 times, resulting in a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 86

Step 3:
130 divided by 86 is 1 with a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 86 from 130 leaves us with 44.
Include the next digit (5) from the dividend after 44, then repeat: 445 / 86

Advancing to step 4:
When dividing 445 by 86, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 430 from 445, we get 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 86

Advancing to step 5:
The number 86 fits into 157 1 times, leaving a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 151.0
The remainder is 71 after subtracting 86 from 157.
Take the next digit (1) from the dividend and append it to 71, then repeat: 711 / 86

On to step 6:
86 can be fit into 711 8 times, resulting in a remainder of 23.
Put 8 as the next digit of the answer. 
Result so far: 1518.0
If we take 688 away from 711, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
86 can be fit into 230 2 times, resulting in a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 1518.2
If we subtract 172 from 230, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 8:
The number 86 fits into 580 6 times, leaving a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 1518.26
The remainder is 64 after subtracting 516 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
If we divide 640 by 86, we get 7 and a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 1518.267
If we take 602 away from 640, 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.

Advancing to step 10:
If we divide 380 by 86, we get 4 and a remainder of 36.
The next digit of our result is 4. 
Result so far: 1518.2674
Deduct 344 from 380 and we're left 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 11:
86 goes into 360 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 1518.26744
Subtracting 344 from 360 leaves us with 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 1518.26744, with a leftover of 1.6e-05.
