We look at the division of 13517 by 60 
The aim is to understand the frequency of 60 in 13517.

Moving on to step 1:
When dividing 1 by 60, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 60

Let's proceed to step 2:
The number 60 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 60

On to step 3:
60 goes into 135 2 times with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 120 from 135 and we're left with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 60

Let's proceed to step 4:
60 goes into 151 2 times with a remainder of 31.
The next digit of our result is 2. 
Result so far: 22.0
Subtract 120 from 151 to get 31.
Include the next digit (7) from the dividend after 31, then repeat: 317 / 60

Going ahead to step 5:
If we divide 317 by 60, we get 5 and a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 225.0
Subtract 300 from 317 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 6:
When dividing 170 by 60, we get 2 with a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 225.2
Subtract 120 from 170 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 7:
The number 60 fits into 500 8 times, leaving a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 225.28
Subtract 480 from 500 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
The number 60 fits into 200 3 times, leaving a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 225.283
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
60 can be fit into 200 3 times, resulting in a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 225.2833
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 225.2833 with a remainder of 0.0002.
