288171 divided by 60 
The aim is to understand the frequency of 60 in 288171.

Step 1:
The number 60 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 60

Going ahead to step 2:
60 can be fit into 28 0 times, resulting in a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 60

Advancing to step 3:
When dividing 288 by 60, we get 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 48 after subtracting 240 from 288.
Fetch the next digit (1) from the dividend, attach it to 48 and continue: 481 / 60

On to step 4:
481 divided by 60 is 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Deduct 480 from 481 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 60

Going ahead to step 5:
60 can be fit into 17 0 times, resulting in a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 480.0
The remainder is 17 after subtracting 0 from 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 60

Moving on to step 6:
When dividing 171 by 60, we get 2 with a remainder of 51.
Record the quotient 2 as the next digit in the result. 
Result so far: 4802.0
Deduct 120 from 171 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
If we divide 510 by 60, we get 8 and a remainder of 30.
The next digit of our result is 8. 
Result so far: 4802.8
Subtracting 480 from 510 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
300 divided by 60 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 4802.85
If we take 300 away from 300, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
60 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4802.85
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
The number 60 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4802.85
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 4802.85, with a leftover of 0.0.
