We divide 648397 by 60
The aim is to understand the frequency of 60 in 648397.

Moving on to step 1:
60 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
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

Moving on to step 2:
When dividing 64 by 60, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 60 from 64 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 60

Going ahead to step 3:
When dividing 48 by 60, we get 0 with a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 48, we end up with 48.
Include the next digit (3) from the dividend after 48, then repeat: 483 / 60

On to step 4:
If we divide 483 by 60, we get 8 and a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
The remainder is 3 after subtracting 480 from 483.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 60

Advancing to step 5:
If we divide 39 by 60, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 1080.0
Deduct 0 from 39 and we're left with 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 60

Going ahead to step 6:
60 goes into 397 6 times with a remainder of 37.
Put 6 as the next digit of the answer. 
Result so far: 10806.0
If we take 360 away from 397, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 7:
60 can be fit into 370 6 times, resulting in a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 10806.6
Subtract 360 from 370 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
60 can be fit into 100 1 times, resulting in a remainder of 40.
The next digit of our result is 1. 
Result so far: 10806.61
Subtract 60 from 100 to 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.

Advancing to step 9:
If we divide 400 by 60, we get 6 and a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 10806.616
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.

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: 10806.6166
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.

The final outcome is 10806.6166, with a leftover of 0.0004.
