We divide 574451 by 60
The aim is to understand the frequency of 60 in 574451.

Step 1:
If we divide 5 by 60, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 60

Moving on to step 2:
When dividing 57 by 60, we get 0 with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Append the next digit (4) from the dividend to 57 and continue with: 574 / 60

Moving on to step 3:
60 goes into 574 9 times with a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 540 from 574 and we're left with 34.
Take the next digit (4) from the dividend and append it to 34, then repeat: 344 / 60

Advancing to step 4:
60 goes into 344 5 times with a remainder of 44.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
The remainder is 44 after subtracting 300 from 344.
Append the next digit (5) from the dividend to 44 and continue with: 445 / 60

On to step 5:
60 goes into 445 7 times with a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 957.0
If we subtract 420 from 445, we get 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 60

Step 6:
60 can be fit into 251 4 times, resulting in a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 9574.0
If we take 240 away from 251, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
The number 60 fits into 110 1 times, leaving a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 9574.1
If we subtract 60 from 110, we 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:
500 divided by 60 is 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 9574.18
If we subtract 480 from 500, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
60 can be fit into 200 3 times, resulting in a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 9574.183
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
60 can be fit into 200 3 times, resulting in a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 9574.1833
Subtract 180 from 200 to get 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 9574.1833 with a remainder of 0.0002.
