409644 divided by 60 
The aim is to understand the frequency of 60 in 409644.

On to step 1:
60 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 60

Advancing to step 2:
When dividing 40 by 60, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Fetch the next digit (9) from the dividend, attach it to 40 and continue: 409 / 60

Moving on to step 3:
If we divide 409 by 60, we get 6 and a remainder of 49.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 360 from 409 to get 49.
Include the next digit (6) from the dividend after 49, then repeat: 496 / 60

Let's proceed to step 4:
60 goes into 496 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 68.0
If we take 480 away from 496, we end up with 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 60

Advancing to step 5:
60 goes into 164 2 times with a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 682.0
Deduct 120 from 164 and we're left with 44.
Take the next digit (4) from the dividend and append it to 44, then repeat: 444 / 60

Moving on to step 6:
The number 60 fits into 444 7 times, leaving a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 6827.0
Deduct 420 from 444 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
If we divide 240 by 60, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 6827.4
Deduct 240 from 240 and we're left 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.

Going ahead to step 8:
0 divided by 60 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6827.4
If we subtract 0 from 0, we 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.

Step 9:
If we divide 0 by 60, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6827.4
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 final result is 6827.4 with a remainder of 0.0.
