We look at the division of 520311 by 60 
The aim is to understand the frequency of 60 in 520311.

Going ahead to step 1:
60 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 60

Step 2:
52 divided by 60 is 0 with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Grab the next digit (0) from the dividend, add it to 52, then carry on: 520 / 60

Step 3:
When dividing 520 by 60, we get 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 480 from 520, we get 40.
Take the next digit (3) from the dividend and append it to 40, then repeat: 403 / 60

On to step 4:
403 divided by 60 is 6 with a remainder of 43.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
If we take 360 away from 403, we end up with 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 60

Let's proceed to step 5:
When dividing 431 by 60, we get 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 867.0
The remainder is 11 after subtracting 420 from 431.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 60

Moving on to step 6:
When dividing 111 by 60, we get 1 with a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 8671.0
Subtracting 60 from 111 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
If we divide 510 by 60, we get 8 and a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 8671.8
If we take 480 away from 510, we end up 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.

Moving on to 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: 8671.85
The remainder is 0 after subtracting 300 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
60 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8671.85
Subtracting 0 from 0 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.

Step 10:
The number 60 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8671.85
If we subtract 0 from 0, we get 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 8671.85, with a leftover of 0.0.
