We divide 575227 by 13
The aim is to understand the frequency of 13 in 575227.

On to step 1:
If we divide 5 by 13, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 13

Step 2:
If we divide 57 by 13, we get 4 and a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 52 from 57 leaves us with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 13

Let's proceed to step 3:
13 can be fit into 55 4 times, resulting in a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
Deduct 52 from 55 and we're left with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 13

Step 4:
When dividing 32 by 13, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 442.0
If we subtract 26 from 32, we get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 13

Step 5:
13 goes into 62 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 4424.0
If we subtract 52 from 62, we get 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 13

Going ahead to step 6:
The number 13 fits into 107 8 times, leaving a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 44248.0
If we take 104 away from 107, 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.

Going ahead to step 7:
The number 13 fits into 30 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 44248.2
Subtract 26 from 30 to 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:
If we divide 40 by 13, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 44248.23
The remainder is 1 after subtracting 39 from 40.
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.
Write down 0 as next digit of the result. 
Result so far: 44248.23
Deduct 0 from 10 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 10:
13 can be fit into 100 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 44248.2307
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.

Let's proceed to step 11:
13 can be fit into 90 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 44248.23076
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.

Moving on to step 12:
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: 44248.230769
If we take 117 away from 120, 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.

Step 13:
If we divide 30 by 13, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 44248.2307692
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.

Moving on to step 14:
13 goes into 40 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 44248.23076923
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.

The final result is 44248.23076923 with a remainder of 1e-09.
