13050970 divided by 86 
The aim is to understand the frequency of 86 in 13050970.

Advancing to step 1:
If we divide 1 by 86, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 86

Moving on to step 2:
If we divide 13 by 86, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 86

On to step 3:
86 can be fit into 130 1 times, resulting in a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 86 from 130, we get 44.
Append the next digit (5) from the dividend to 44 and continue with: 445 / 86

Step 4:
86 can be fit into 445 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 15 after subtracting 430 from 445.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 86

Advancing to step 5:
If we divide 150 by 86, we get 1 and a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 151.0
If we subtract 86 from 150, we get 64.
Bring next digit (9) of the dividend behind the 64 and repeat the process: 649 / 86

On to step 6:
649 divided by 86 is 7 with a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 1517.0
If we take 602 away from 649, we end up with 47.
Grab the next digit (7) from the dividend, add it to 47, then carry on: 477 / 86

Let's proceed to step 7:
477 divided by 86 is 5 with a remainder of 47.
Use 5 as the next digit of our solution. 
Result so far: 15175.0
Deduct 430 from 477 and we're left with 47.
Grab the next digit (0) from the dividend, add it to 47, then carry on: 470 / 86

Let's proceed to step 8:
86 can be fit into 470 5 times, resulting in a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 151755.0
Deduct 430 from 470 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
If we divide 400 by 86, we get 4 and a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 151755.4
If we subtract 344 from 400, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
86 goes into 560 6 times with a remainder of 44.
The next digit of our result is 6. 
Result so far: 151755.46
If we take 516 away from 560, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 11:
86 can be fit into 440 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 151755.465
Deduct 430 from 440 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
When dividing 100 by 86, we get 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 151755.4651
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
86 can be fit into 140 1 times, resulting in a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 151755.46511
If we subtract 86 from 140, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 151755.46511 with a remaining 5.4e-05.
