We divide 187086 by 13
The aim is to understand the frequency of 13 in 187086.

On to step 1:
13 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 13

Let's proceed to step 2:
If we divide 18 by 13, we get 1 and a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 13 from 18 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 13

On to step 3:
When dividing 57 by 13, we get 4 with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 52 from 57, we get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 13

Step 4:
50 divided by 13 is 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 143.0
If we subtract 39 from 50, we get 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 13

Advancing to step 5:
The number 13 fits into 118 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 1439.0
If we subtract 117 from 118, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 13

Step 6:
13 goes into 16 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 14391.0
If we subtract 13 from 16, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
13 can be fit into 30 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 14391.2
Subtracting 26 from 30 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
When dividing 40 by 13, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 14391.23
If we take 39 away from 40, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
13 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 14391.23
If we take 0 away from 10, we end up 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 10:
When dividing 100 by 13, we get 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 14391.2307
If we subtract 91 from 100, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
90 divided by 13 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 14391.23076
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
13 goes into 120 9 times with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 14391.230769
Subtract 117 from 120 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 13:
13 can be fit into 30 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 14391.2307692
Subtracting 26 from 30 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
When dividing 40 by 13, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 14391.23076923
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 14391.23076923 with a remaining 1e-09.
