We look at the division of 509433 by 60 
The aim is to understand the frequency of 60 in 509433.

Step 1:
60 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 60

Let's proceed to step 2:
50 divided by 60 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Append the next digit (9) from the dividend to 50 and continue with: 509 / 60

On to step 3:
If we divide 509 by 60, we get 8 and a remainder of 29.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 480 from 509 and we're left with 29.
Bring next digit (4) of the dividend behind the 29 and repeat the process: 294 / 60

On to step 4:
The number 60 fits into 294 4 times, leaving a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
The remainder is 54 after subtracting 240 from 294.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 60

Going ahead to step 5:
The number 60 fits into 543 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 849.0
If we subtract 540 from 543, we get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 60

On to step 6:
33 divided by 60 is 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 8490.0
Deduct 0 from 33 and we're left with 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.
The number 5 becomes the next digit in our result. 
Result so far: 8490.5
Subtract 300 from 330 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
The number 60 fits into 300 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 8490.55
If we take 300 away from 300, we end up 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.

In conclusion, the division gives 8490.55 with a balance of 0.0.
