308960 divided by 60 
The aim is to understand the frequency of 60 in 308960.

Step 1:
When dividing 3 by 60, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 60

Moving on to step 2:
60 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Include the next digit (8) from the dividend after 30, then repeat: 308 / 60

Advancing to step 3:
308 divided by 60 is 5 with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 300 from 308 and we're left with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 60

Step 4:
The number 60 fits into 89 1 times, leaving a remainder of 29.
The next digit of our result is 1. 
Result so far: 51.0
If we take 60 away from 89, we end up with 29.
Append the next digit (6) from the dividend to 29 and continue with: 296 / 60

Step 5:
The number 60 fits into 296 4 times, leaving a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 514.0
If we take 240 away from 296, we end up with 56.
Bring next digit (0) of the dividend behind the 56 and repeat the process: 560 / 60

Going ahead to step 6:
560 divided by 60 is 9 with a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 5149.0
Subtract 540 from 560 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.

Let's proceed to step 7:
60 can be fit into 200 3 times, resulting in a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 5149.3
Subtracting 180 from 200 leaves us 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.

On to step 8:
If we divide 200 by 60, we get 3 and a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 5149.33
If we take 180 away from 200, we end up 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.

The final outcome is 5149.33, with a leftover of 0.02.
