64015104 divided by 609 
The aim is to understand the frequency of 609 in 64015104.

Advancing to step 1:
609 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 609

Advancing to step 2:
609 goes into 64 0 times with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (0) from the dividend to 64 and continue with: 640 / 609

Step 3:
The number 609 fits into 640 1 times, leaving a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 609 from 640, we get 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 609

Let's proceed to step 4:
311 divided by 609 is 0 with a remainder of 311.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 311, we get 311.
Fetch the next digit (5) from the dividend, attach it to 311 and continue: 3115 / 609

Step 5:
609 can be fit into 3115 5 times, resulting in a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
Subtracting 3045 from 3115 leaves us with 70.
Grab the next digit (1) from the dividend, add it to 70, then carry on: 701 / 609

Advancing to step 6:
609 can be fit into 701 1 times, resulting in a remainder of 92.
Record the quotient 1 as the next digit in the result. 
Result so far: 1051.0
Subtract 609 from 701 to get 92.
Grab the next digit (0) from the dividend, add it to 92, then carry on: 920 / 609

Step 7:
If we divide 920 by 609, we get 1 and a remainder of 311.
The next digit of our result is 1. 
Result so far: 10511.0
If we subtract 609 from 920, we get 311.
Bring next digit (4) of the dividend behind the 311 and repeat the process: 3114 / 609

Let's proceed to step 8:
609 goes into 3114 5 times with a remainder of 69.
Write down 5 as next digit of the result. 
Result so far: 105115.0
Subtract 3045 from 3114 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 9:
609 can be fit into 690 1 times, resulting in a remainder of 81.
Put 1 as the next digit of the answer. 
Result so far: 105115.1
If we subtract 609 from 690, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 10:
609 goes into 810 1 times with a remainder of 201.
Write down 1 as next digit of the result. 
Result so far: 105115.11
Subtracting 609 from 810 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

The final result is 105115.11 with a remainder of 0.201.
