64594587 divided by 12 
The aim is to understand the frequency of 12 in 64594587.

Advancing to step 1:
12 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 12

Going ahead to step 2:
64 divided by 12 is 5 with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 4 after subtracting 60 from 64.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 12

Advancing to step 3:
12 can be fit into 45 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 53.0
The remainder is 9 after subtracting 36 from 45.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 12

Moving on to step 4:
The number 12 fits into 99 8 times, leaving a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 538.0
Subtract 96 from 99 to get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 12

Advancing to step 5:
When dividing 34 by 12, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 5382.0
The remainder is 10 after subtracting 24 from 34.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 12

Let's proceed to step 6:
12 can be fit into 105 8 times, resulting in a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 53828.0
If we take 96 away from 105, we end up with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 12

Advancing to step 7:
98 divided by 12 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 538288.0
If we subtract 96 from 98, we get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 12

Moving on to step 8:
27 divided by 12 is 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 5382882.0
If we subtract 24 from 27, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
30 divided by 12 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 5382882.2
If we take 24 away from 30, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
12 goes into 60 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5382882.25
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
If we divide 0 by 12, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 5382882.25
Deduct 0 from 0 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.

On to step 12:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5382882.25
If we take 0 away from 0, we end up 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.

The final outcome is 5382882.25, with a leftover of 0.0.
