We look at the division of 567606 by 13 
The aim is to understand the frequency of 13 in 567606.

On to step 1:
13 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 13

On to step 2:
56 divided by 13 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 52 from 56 leaves us with 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 13

Let's proceed to step 3:
13 goes into 47 3 times with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 43.0
The remainder is 8 after subtracting 39 from 47.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 13

Advancing to step 4:
The number 13 fits into 86 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 436.0
Subtracting 78 from 86 leaves us with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 13

Step 5:
13 goes into 80 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 4366.0
If we take 78 away from 80, we end up with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 13

Let's proceed to step 6:
13 goes into 26 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 43662.0
Subtracting 26 from 26 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
The number 13 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 43662.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
0 divided by 13 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 43662.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 43662.0, and the remainder is 0.0.
