We're dividing 728642 by 60 
The aim is to understand the frequency of 60 in 728642.

Let's proceed to step 1:
7 divided by 60 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 60

Let's proceed to step 2:
If we divide 72 by 60, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 60 away from 72, we end up with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 60

On to step 3:
The number 60 fits into 128 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 120 from 128 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 60

Moving on to step 4:
When dividing 86 by 60, we get 1 with a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 121.0
If we take 60 away from 86, we end up with 26.
Fetch the next digit (4) from the dividend, attach it to 26 and continue: 264 / 60

On to step 5:
264 divided by 60 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 1214.0
If we subtract 240 from 264, we get 24.
Take the next digit (2) from the dividend and append it to 24, then repeat: 242 / 60

On to step 6:
242 divided by 60 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 12144.0
If we take 240 away from 242, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
The number 60 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 12144.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
When dividing 200 by 60, we get 3 with a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 12144.03
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
If we divide 200 by 60, we get 3 and a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 12144.033
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 12144.033 and a remainder of 0.002.
