We look at the division of 109991 by 60 
The aim is to understand the frequency of 60 in 109991.

Let's proceed to step 1:
The number 60 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 60

Moving on to step 2:
60 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 60

On to step 3:
If we divide 109 by 60, we get 1 and a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 60 from 109 and we're left with 49.
Bring next digit (9) of the dividend behind the 49 and repeat the process: 499 / 60

Let's proceed to step 4:
If we divide 499 by 60, we get 8 and a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 19 after subtracting 480 from 499.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 60

On to step 5:
199 divided by 60 is 3 with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 183.0
The remainder is 19 after subtracting 180 from 199.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 60

Let's proceed to step 6:
60 can be fit into 191 3 times, resulting in a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 1833.0
If we subtract 180 from 191, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
60 can be fit into 110 1 times, resulting in a remainder of 50.
The next digit of our result is 1. 
Result so far: 1833.1
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.

Advancing to step 8:
If we divide 500 by 60, we get 8 and a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 1833.18
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.

Advancing to step 9:
200 divided by 60 is 3 with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 1833.183
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.

Step 10:
60 can be fit into 200 3 times, resulting in a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 1833.1833
If we take 180 away from 200, we end up 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 1833.1833 with a remainder of 0.0002.
