137439 ÷ 60 
The aim is to understand the frequency of 60 in 137439.

Advancing to step 1:
60 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 60

Let's proceed to step 2:
60 goes into 13 0 times with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 60

Going ahead to step 3:
When dividing 137 by 60, we get 2 with a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 120 from 137 leaves us with 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 60

Step 4:
60 can be fit into 174 2 times, resulting in a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 120 from 174 to get 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 60

Moving on to step 5:
543 divided by 60 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 229.0
Subtract 540 from 543 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 60

Step 6:
The number 60 fits into 39 0 times, leaving a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 2290.0
If we take 0 away from 39, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
390 divided by 60 is 6 with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 2290.6
Subtracting 360 from 390 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.

Moving on to step 8:
60 goes into 300 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 2290.65
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.

Advancing to step 9:
The number 60 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2290.65
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
0 divided by 60 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2290.65
Subtract 0 from 0 to get 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 2290.65, with a leftover of 0.0.
