We look at the division of 308297 by 60 
The aim is to understand the frequency of 60 in 308297.

On to step 1:
3 divided by 60 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 60

Going ahead to step 2:
60 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (8) from the dividend to 30 and continue with: 308 / 60

Advancing to step 3:
60 goes into 308 5 times 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.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 60

Let's proceed to step 4:
60 can be fit into 82 1 times, resulting in a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtracting 60 from 82 leaves us with 22.
Fetch the next digit (9) from the dividend, attach it to 22 and continue: 229 / 60

Advancing to step 5:
The number 60 fits into 229 3 times, leaving a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 513.0
The remainder is 49 after subtracting 180 from 229.
Include the next digit (7) from the dividend after 49, then repeat: 497 / 60

Going ahead to step 6:
The number 60 fits into 497 8 times, leaving a remainder of 17.
Put 8 as the next digit of the answer. 
Result so far: 5138.0
Deduct 480 from 497 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
60 goes into 170 2 times with a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 5138.2
If we take 120 away from 170, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
500 divided by 60 is 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 5138.28
Deduct 480 from 500 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.

Moving on to step 9:
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: 5138.283
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.

Step 10:
When dividing 200 by 60, we get 3 with a remainder of 20.
The next digit of our result is 3. 
Result so far: 5138.2833
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 5138.2833 and a remainder of 0.0002.
