We're dividing 7787574 by 60 
The aim is to understand the frequency of 60 in 7787574.

Step 1:
7 divided by 60 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 60

Moving on to step 2:
60 can be fit into 77 1 times, resulting in a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 60 from 77 leaves us with 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 60

Going ahead to step 3:
60 can be fit into 178 2 times, resulting in a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 120 from 178 leaves us with 58.
Take the next digit (7) from the dividend and append it to 58, then repeat: 587 / 60

Let's proceed to step 4:
The number 60 fits into 587 9 times, leaving a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
If we subtract 540 from 587, we get 47.
Fetch the next digit (5) from the dividend, attach it to 47 and continue: 475 / 60

On to step 5:
When dividing 475 by 60, we get 7 with a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 1297.0
If we take 420 away from 475, we end up with 55.
Append the next digit (7) from the dividend to 55 and continue with: 557 / 60

Advancing to step 6:
The number 60 fits into 557 9 times, leaving a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 12979.0
Subtracting 540 from 557 leaves us with 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 60

Moving on to step 7:
If we divide 174 by 60, we get 2 and a remainder of 54.
Record the quotient 2 as the next digit in the result. 
Result so far: 129792.0
If we subtract 120 from 174, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 8:
The number 60 fits into 540 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 129792.9
If we take 540 away from 540, 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 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 129792.9
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.

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: 129792.9
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.

In conclusion, the division gives 129792.9 with a balance of 0.0.
