We look at the division of 10388 by 60 
The aim is to understand the frequency of 60 in 10388.

Advancing to step 1:
If we divide 1 by 60, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 60

Step 2:
10 divided by 60 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 60

On to step 3:
103 divided by 60 is 1 with a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 60 from 103 and we're left with 43.
Bring next digit (8) of the dividend behind the 43 and repeat the process: 438 / 60

Step 4:
The number 60 fits into 438 7 times, leaving a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 420 from 438, we get 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 60

Moving on to step 5:
188 divided by 60 is 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 173.0
Subtracting 180 from 188 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 6:
If we divide 80 by 60, we get 1 and a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 173.1
Subtract 60 from 80 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.

Let's proceed to step 7:
60 goes into 200 3 times with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 173.13
If we subtract 180 from 200, 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.

Step 8:
When dividing 200 by 60, we get 3 with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 173.133
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.

The final result is 173.133 with a remainder of 0.002.
