599749 divided by 13 
The aim is to understand the frequency of 13 in 599749.

On to step 1:
13 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 13

Moving on to step 2:
If we divide 59 by 13, we get 4 and a remainder of 7.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 52 from 59 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 13

Advancing to step 3:
The number 13 fits into 79 6 times, leaving a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 46.0
Subtracting 78 from 79 leaves us with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 13

Moving on to step 4:
If we divide 17 by 13, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 461.0
Deduct 13 from 17 and we're left with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 13

Step 5:
13 goes into 44 3 times with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 4613.0
Subtracting 39 from 44 leaves us with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 13

Let's proceed to step 6:
The number 13 fits into 59 4 times, leaving a remainder of 7.
The next digit of our result is 4. 
Result so far: 46134.0
The remainder is 7 after subtracting 52 from 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
13 can be fit into 70 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 46134.5
The remainder is 5 after subtracting 65 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
When dividing 50 by 13, we get 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 46134.53
If we take 39 away from 50, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
When dividing 110 by 13, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 46134.538
If we subtract 104 from 110, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
13 can be fit into 60 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 46134.5384
If we take 52 away from 60, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
When dividing 80 by 13, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 46134.53846
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
13 goes into 20 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 46134.538461
Subtract 13 from 20 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 13:
13 goes into 70 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 46134.5384615
The remainder is 5 after subtracting 65 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 14:
50 divided by 13 is 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 46134.53846153
If we subtract 39 from 50, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 46134.53846153 and a remainder of 1.1e-08.
