We're dividing 604546 by 60 
The aim is to understand the frequency of 60 in 604546.

Advancing to step 1:
The number 60 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 60

On to step 2:
The number 60 fits into 60 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 60 away from 60, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 60

Advancing to step 3:
The number 60 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 60

Step 4:
60 can be fit into 45 0 times, resulting in a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 100.0
Deduct 0 from 45 and we're left with 45.
Grab the next digit (4) from the dividend, add it to 45, then carry on: 454 / 60

Let's proceed to step 5:
If we divide 454 by 60, we get 7 and a remainder of 34.
The next digit of our result is 7. 
Result so far: 1007.0
Subtract 420 from 454 to get 34.
Bring next digit (6) of the dividend behind the 34 and repeat the process: 346 / 60

Moving on to step 6:
346 divided by 60 is 5 with a remainder of 46.
Write down 5 as next digit of the result. 
Result so far: 10075.0
Subtracting 300 from 346 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
60 can be fit into 460 7 times, resulting in a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 10075.7
Subtracting 420 from 460 leaves us 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 goes into 400 6 times with a remainder of 40.
The next digit of our result is 6. 
Result so far: 10075.76
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
If we divide 400 by 60, we get 6 and a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 10075.766
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 10075.766 and a remainder of 0.004.
