We look at the division of 913660 by 60 
The aim is to understand the frequency of 60 in 913660.

On to step 1:
60 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 60

Advancing to step 2:
91 divided by 60 is 1 with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 60 away from 91, we end up with 31.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 60

Step 3:
If we divide 313 by 60, we get 5 and a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 300 from 313 leaves us with 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 60

Moving on to step 4:
136 divided by 60 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 152.0
Subtracting 120 from 136 leaves us with 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 60

Going ahead to step 5:
60 can be fit into 166 2 times, resulting in a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 1522.0
If we subtract 120 from 166, we get 46.
Fetch the next digit (0) from the dividend, attach it to 46 and continue: 460 / 60

Going ahead to step 6:
60 can be fit into 460 7 times, resulting in a remainder of 40.
The next digit of our result is 7. 
Result so far: 15227.0
If we take 420 away from 460, we end up 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.

Going ahead to step 7:
400 divided by 60 is 6 with a remainder of 40.
The next digit of our result is 6. 
Result so far: 15227.6
If we take 360 away from 400, we end up 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.

On to step 8:
If we divide 400 by 60, we get 6 and a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 15227.66
If we subtract 360 from 400, we get 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 final outcome is 15227.66, with a leftover of 0.04.
