668499 divided by 60 
The aim is to understand the frequency of 60 in 668499.

On to step 1:
6 divided by 60 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 60

On to step 2:
The number 60 fits into 66 1 times, leaving a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 60 from 66, we get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 60

Advancing to step 3:
When dividing 68 by 60, we get 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 60 from 68 to get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 60

Let's proceed to step 4:
The number 60 fits into 84 1 times, leaving a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 111.0
If we subtract 60 from 84, we get 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 60

Advancing to step 5:
When dividing 249 by 60, we get 4 with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 1114.0
If we subtract 240 from 249, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 60

Step 6:
60 can be fit into 99 1 times, resulting in a remainder of 39.
The next digit of our result is 1. 
Result so far: 11141.0
Subtracting 60 from 99 leaves us 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.

Going ahead to step 7:
60 goes into 390 6 times with a remainder of 30.
The next digit of our result is 6. 
Result so far: 11141.6
Subtract 360 from 390 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
60 goes into 300 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 11141.65
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.

Step 9:
0 divided by 60 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11141.65
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.

Advancing to step 10:
The number 60 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11141.65
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 quotient of the division is 11141.65, and the remainder is 0.0.
