66935305 ÷ 60 
The aim is to understand the frequency of 60 in 66935305.

Advancing to step 1:
The number 60 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 60

Advancing to step 2:
When dividing 66 by 60, we get 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
If we take 60 away from 66, we end up with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 60

Moving on to step 3:
69 divided by 60 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 9 after subtracting 60 from 69.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 60

Going ahead to step 4:
If we divide 93 by 60, we get 1 and a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 111.0
If we take 60 away from 93, we end up with 33.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 60

Advancing to step 5:
60 can be fit into 335 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 1115.0
If we take 300 away from 335, we end up with 35.
Fetch the next digit (3) from the dividend, attach it to 35 and continue: 353 / 60

Let's proceed to step 6:
The number 60 fits into 353 5 times, leaving a remainder of 53.
The number 5 becomes the next digit in our result. 
Result so far: 11155.0
The remainder is 53 after subtracting 300 from 353.
Bring next digit (0) of the dividend behind the 53 and repeat the process: 530 / 60

Let's proceed to step 7:
530 divided by 60 is 8 with a remainder of 50.
The number 8 becomes the next digit in our result. 
Result so far: 111558.0
The remainder is 50 after subtracting 480 from 530.
Fetch the next digit (5) from the dividend, attach it to 50 and continue: 505 / 60

Advancing to step 8:
60 can be fit into 505 8 times, resulting in a remainder of 25.
Write down 8 as next digit of the result. 
Result so far: 1115588.0
Subtract 480 from 505 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
When dividing 250 by 60, we get 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 1115588.4
Subtracting 240 from 250 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
60 can be fit into 100 1 times, resulting in a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 1115588.41
Deduct 60 from 100 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
400 divided by 60 is 6 with a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 1115588.416
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
If we divide 400 by 60, we get 6 and a remainder of 40.
The next digit of our result is 6. 
Result so far: 1115588.4166
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 1115588.4166, and the remainder is 0.0004.
