We look at the division of 730450 by 60 
The aim is to understand the frequency of 60 in 730450.

On to step 1:
If we divide 7 by 60, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 60

Step 2:
The number 60 fits into 73 1 times, leaving a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 13 after subtracting 60 from 73.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 60

On to step 3:
60 goes into 130 2 times with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 10 after subtracting 120 from 130.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 60

Going ahead to step 4:
60 can be fit into 104 1 times, resulting in a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 121.0
Subtract 60 from 104 to get 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 60

Advancing to step 5:
If we divide 445 by 60, we get 7 and a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 1217.0
If we subtract 420 from 445, we get 25.
Include the next digit (0) from the dividend after 25, then repeat: 250 / 60

Going ahead to step 6:
250 divided by 60 is 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 12174.0
If we subtract 240 from 250, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
60 can be fit into 100 1 times, resulting in a remainder of 40.
The next digit of our result is 1. 
Result so far: 12174.1
If we subtract 60 from 100, 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.

Let's proceed to step 8:
60 goes into 400 6 times with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 12174.16
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.

Moving on to step 9:
If we divide 400 by 60, we get 6 and a remainder of 40.
The next digit of our result is 6. 
Result so far: 12174.166
Subtracting 360 from 400 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.

The final outcome is 12174.166, with a leftover of 0.004.
