We look at the division of 450173 by 60 
The aim is to understand the frequency of 60 in 450173.

On to step 1:
60 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 60

Advancing to step 2:
If we divide 45 by 60, we get 0 and a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 60

Step 3:
When dividing 450 by 60, we get 7 with a remainder of 30.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 420 from 450 to get 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 60

On to step 4:
60 can be fit into 301 5 times, resulting in a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 75.0
If we subtract 300 from 301, we get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 60

On to step 5:
17 divided by 60 is 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 750.0
If we take 0 away from 17, we end up with 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 60

Moving on to step 6:
173 divided by 60 is 2 with a remainder of 53.
Record the quotient 2 as the next digit in the result. 
Result so far: 7502.0
Subtracting 120 from 173 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
60 goes into 530 8 times with a remainder of 50.
Use 8 as the next digit of our solution. 
Result so far: 7502.8
Subtract 480 from 530 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
60 goes into 500 8 times with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 7502.88
Subtracting 480 from 500 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 7502.88 with a remainder of 0.02.
