404573 ÷ 60 
The aim is to understand the frequency of 60 in 404573.

Going ahead to step 1:
60 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 60

Going ahead to step 2:
40 divided by 60 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Bring next digit (4) of the dividend behind the 40 and repeat the process: 404 / 60

Step 3:
When dividing 404 by 60, we get 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 360 from 404 to get 44.
Include the next digit (5) from the dividend after 44, then repeat: 445 / 60

Moving on to step 4:
60 can be fit into 445 7 times, resulting in a remainder of 25.
The next digit of our result is 7. 
Result so far: 67.0
Subtract 420 from 445 to get 25.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 60

Let's proceed to step 5:
257 divided by 60 is 4 with a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 674.0
Subtract 240 from 257 to get 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 60

Moving on to step 6:
60 goes into 173 2 times with a remainder of 53.
The number 2 becomes the next digit in our result. 
Result so far: 6742.0
Subtract 120 from 173 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 7:
60 can be fit into 530 8 times, resulting in a remainder of 50.
The next digit of our result is 8. 
Result so far: 6742.8
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.

Advancing to step 8:
60 goes into 500 8 times with a remainder of 20.
The next digit of our result is 8. 
Result so far: 6742.88
Deduct 480 from 500 and we're left 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.

After the division, we end up with 6742.88 and a remainder of 0.02.
