We're dividing 644809 by 60 
The aim is to understand the frequency of 60 in 644809.

Moving on to step 1:
60 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 60

Step 2:
If we divide 64 by 60, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 60 from 64 and we're left with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 60

Going ahead to step 3:
If we divide 44 by 60, we get 0 and a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 44 leaves us with 44.
Bring next digit (8) of the dividend behind the 44 and repeat the process: 448 / 60

Moving on to step 4:
When dividing 448 by 60, we get 7 with a remainder of 28.
Write down 7 as next digit of the result. 
Result so far: 107.0
Subtracting 420 from 448 leaves us with 28.
Include the next digit (0) from the dividend after 28, then repeat: 280 / 60

Moving on to step 5:
When dividing 280 by 60, we get 4 with a remainder of 40.
The next digit of our result is 4. 
Result so far: 1074.0
The remainder is 40 after subtracting 240 from 280.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 60

Going ahead to step 6:
60 can be fit into 409 6 times, resulting in a remainder of 49.
The number 6 becomes the next digit in our result. 
Result so far: 10746.0
Subtracting 360 from 409 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
60 can be fit into 490 8 times, resulting in a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 10746.8
If we take 480 away from 490, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 60 is 1 with a remainder of 40.
The next digit of our result is 1. 
Result so far: 10746.81
Subtracting 60 from 100 leaves us 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 9:
If we divide 400 by 60, we get 6 and a remainder of 40.
The next digit of our result is 6. 
Result so far: 10746.816
Deduct 360 from 400 and we're left 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.

Step 10:
60 goes into 400 6 times with a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 10746.8166
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.

Our division results in 10746.8166 with a remaining 0.0004.
