We divide 560297 by 13
The aim is to understand the frequency of 13 in 560297.

Advancing to step 1:
5 divided by 13 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 13

Step 2:
13 goes into 56 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 4 after subtracting 52 from 56.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 13

On to step 3:
The number 13 fits into 40 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 43.0
The remainder is 1 after subtracting 39 from 40.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 13

Moving on to step 4:
12 divided by 13 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 430.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 13

Let's proceed to step 5:
If we divide 129 by 13, we get 9 and a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 4309.0
The remainder is 12 after subtracting 117 from 129.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 13

On to step 6:
The number 13 fits into 127 9 times, leaving a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 43099.0
The remainder is 10 after subtracting 117 from 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
The number 13 fits into 100 7 times, leaving a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 43099.7
Subtracting 91 from 100 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 8:
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: 43099.76
If we subtract 78 from 90, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
When dividing 120 by 13, we get 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 43099.769
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.

Going ahead to step 10:
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: 43099.7692
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.

Let's proceed to step 11:
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: 43099.76923
If we subtract 39 from 40, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 12:
10 divided by 13 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 43099.76923
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.

Moving on to step 13:
13 goes into 100 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 43099.7692307
Subtracting 91 from 100 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 14:
If we divide 90 by 13, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 43099.76923076
If we take 78 away from 90, we end up 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.

The quotient of the division is 43099.76923076, and the remainder is 1.2e-08.
