We look at the division of 854611 by 13 
The aim is to understand the frequency of 13 in 854611.

Going ahead to step 1:
The number 13 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 13

Let's proceed to step 2:
If we divide 85 by 13, we get 6 and a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 78 away from 85, we end up with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 13

Let's proceed to step 3:
The number 13 fits into 74 5 times, leaving a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 65.0
Subtract 65 from 74 to get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 13

On to step 4:
When dividing 96 by 13, we get 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 657.0
If we subtract 91 from 96, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 13

Advancing to step 5:
The number 13 fits into 51 3 times, leaving a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 6573.0
Deduct 39 from 51 and we're left with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 13

Moving on to step 6:
The number 13 fits into 121 9 times, leaving a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 65739.0
If we subtract 117 from 121, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
13 can be fit into 40 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 65739.3
Subtracting 39 from 40 leaves us 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.

Step 8:
If we divide 10 by 13, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 65739.3
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
If we divide 100 by 13, we get 7 and a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 65739.307
Subtract 91 from 100 to 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.

Advancing to step 10:
13 goes into 90 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 65739.3076
Deduct 78 from 90 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
If we divide 120 by 13, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 65739.30769
Subtracting 117 from 120 leaves us with 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 12:
When dividing 30 by 13, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 65739.307692
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.

Step 13:
The number 13 fits into 40 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 65739.3076923
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.

Moving on to step 14:
If we divide 10 by 13, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 65739.3076923
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 65739.3076923 with a remaining 1e-08.
