468211 ÷ 13 
The aim is to understand the frequency of 13 in 468211.

On to step 1:
4 divided by 13 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 13

Going ahead to step 2:
13 can be fit into 46 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 39 from 46 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 13

Going ahead to step 3:
When dividing 78 by 13, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 36.0
The remainder is 0 after subtracting 78 from 78.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 13

On to step 4:
2 divided by 13 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 360.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 13

Step 5:
21 divided by 13 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 3601.0
If we take 13 away from 21, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 13

On to step 6:
The number 13 fits into 81 6 times, leaving a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 36016.0
If we take 78 away from 81, we end up 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.

Moving on to step 7:
When dividing 30 by 13, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 36016.2
If we subtract 26 from 30, 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.

On to step 8:
40 divided by 13 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 36016.23
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.

On to step 9:
13 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 36016.23
Subtracting 0 from 10 leaves us 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.

Step 10:
When dividing 100 by 13, we get 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 36016.2307
The remainder is 9 after subtracting 91 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 11:
13 can be fit into 90 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 36016.23076
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.

Advancing to step 12:
13 can be fit into 120 9 times, resulting in a remainder of 3.
The next digit of our result is 9. 
Result so far: 36016.230769
The remainder is 3 after subtracting 117 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 13:
The number 13 fits into 30 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 36016.2307692
Deduct 26 from 30 and we're left 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.

Moving on to step 14:
40 divided by 13 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 36016.23076923
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.

Our division results in 36016.23076923 with a remaining 1e-09.
