We look at the division of 781713 by 60 
The aim is to understand the frequency of 60 in 781713.

Going ahead to step 1:
The number 60 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 60

Moving on to step 2:
60 can be fit into 78 1 times, resulting in a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 60 from 78 to get 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 60

Let's proceed to step 3:
60 can be fit into 181 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 1 after subtracting 180 from 181.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 60

Going ahead to step 4:
When dividing 17 by 60, we get 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 130.0
Subtract 0 from 17 to get 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 60

Step 5:
60 goes into 171 2 times with a remainder of 51.
The number 2 becomes the next digit in our result. 
Result so far: 1302.0
Deduct 120 from 171 and we're left with 51.
Include the next digit (3) from the dividend after 51, then repeat: 513 / 60

Step 6:
513 divided by 60 is 8 with a remainder of 33.
Use 8 as the next digit of our solution. 
Result so far: 13028.0
If we subtract 480 from 513, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
60 can be fit into 330 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 13028.5
Deduct 300 from 330 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
60 can be fit into 300 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 13028.55
Subtracting 300 from 300 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.

The final outcome is 13028.55, with a leftover of 0.0.
