The aim is to understand the frequency of 99 in 64412475.

Let's proceed to step 1:
The number 99 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 99

Going ahead to step 2:
When dividing 64 by 99, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Take the next digit (4) from the dividend and append it to 64, then repeat: 644 / 99

Let's proceed to step 3:
644 divided by 99 is 6 with a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 594 from 644 and we're left with 50.
Bring next digit (1) of the dividend behind the 50 and repeat the process: 501 / 99

On to step 4:
99 can be fit into 501 5 times, resulting in a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
Deduct 495 from 501 and we're left with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 99

Let's proceed to step 5:
When dividing 62 by 99, we get 0 with a remainder of 62.
The number 0 becomes the next digit in our result. 
Result so far: 650.0
Deduct 0 from 62 and we're left with 62.
Take the next digit (4) from the dividend and append it to 62, then repeat: 624 / 99

Step 6:
99 goes into 624 6 times with a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 6506.0
Deduct 594 from 624 and we're left with 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 99

Moving on to step 7:
99 goes into 307 3 times with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 65063.0
Deduct 297 from 307 and we're left with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 99

Step 8:
If we divide 105 by 99, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 650631.0
Deduct 99 from 105 and we're left 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.

Advancing to step 9:
The number 99 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 650631.0
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
If we divide 600 by 99, we get 6 and a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 650631.06
Deduct 594 from 600 and we're left 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.

Advancing to step 11:
60 divided by 99 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 650631.06
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
600 divided by 99 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 650631.0606
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
99 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 650631.0606
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 14:
When dividing 600 by 99, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 650631.060606
Subtracting 594 from 600 leaves us 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.

Advancing to step 15:
60 divided by 99 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 650631.060606
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 16:
600 divided by 99 is 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 650631.06060606
If we take 594 away from 600, 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.

The final result is 650631.06060606 with a remainder of 6e-09.
