We're dividing 585142 by 60 
The aim is to understand the frequency of 60 in 585142.

On to step 1:
When dividing 5 by 60, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 60

On to step 2:
If we divide 58 by 60, we get 0 and a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Take the next digit (5) from the dividend and append it to 58, then repeat: 585 / 60

Step 3:
When dividing 585 by 60, we get 9 with a remainder of 45.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 45 after subtracting 540 from 585.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 60

Moving on to step 4:
When dividing 451 by 60, we get 7 with a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Subtracting 420 from 451 leaves us with 31.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 60

Step 5:
The number 60 fits into 314 5 times, leaving a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 975.0
Subtract 300 from 314 to get 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 60

Advancing to step 6:
When dividing 142 by 60, we get 2 with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 9752.0
Subtract 120 from 142 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
When dividing 220 by 60, we get 3 with a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 9752.3
If we take 180 away from 220, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
60 can be fit into 400 6 times, resulting in a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 9752.36
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
400 divided by 60 is 6 with a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 9752.366
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 9752.366, with a leftover of 0.004.
