728813 ÷ 60 
The aim is to understand the frequency of 60 in 728813.

Going ahead to step 1:
The number 60 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 60

Going ahead to step 2:
When dividing 72 by 60, we get 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 60 from 72 and we're left with 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 60

Step 3:
If we divide 128 by 60, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 120 away from 128, we end up with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 60

Step 4:
88 divided by 60 is 1 with a remainder of 28.
The next digit of our result is 1. 
Result so far: 121.0
The remainder is 28 after subtracting 60 from 88.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 60

Going ahead to step 5:
The number 60 fits into 281 4 times, leaving a remainder of 41.
Use 4 as the next digit of our solution. 
Result so far: 1214.0
Subtracting 240 from 281 leaves us with 41.
Include the next digit (3) from the dividend after 41, then repeat: 413 / 60

Step 6:
60 can be fit into 413 6 times, resulting in a remainder of 53.
The next digit of our result is 6. 
Result so far: 12146.0
If we subtract 360 from 413, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 7:
The number 60 fits into 530 8 times, leaving a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 12146.8
If we take 480 away from 530, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
500 divided by 60 is 8 with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 12146.88
Subtract 480 from 500 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 12146.88, with a leftover of 0.02.
