64604965 ÷ 501 
The aim is to understand the frequency of 501 in 64604965.

Step 1:
6 divided by 501 is 0 with a remainder of 6.
The next digit of our result is 0. 
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 / 501

Step 2:
The number 501 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Fetch the next digit (6) from the dividend, attach it to 64 and continue: 646 / 501

Moving on to step 3:
501 goes into 646 1 times with a remainder of 145.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 145 after subtracting 501 from 646.
Include the next digit (0) from the dividend after 145, then repeat: 1450 / 501

On to step 4:
If we divide 1450 by 501, we get 2 and a remainder of 448.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 1002 away from 1450, we end up with 448.
Fetch the next digit (4) from the dividend, attach it to 448 and continue: 4484 / 501

Step 5:
When dividing 4484 by 501, we get 8 with a remainder of 476.
The next digit of our result is 8. 
Result so far: 128.0
If we take 4008 away from 4484, we end up with 476.
Take the next digit (9) from the dividend and append it to 476, then repeat: 4769 / 501

Step 6:
501 can be fit into 4769 9 times, resulting in a remainder of 260.
The next digit of our result is 9. 
Result so far: 1289.0
If we subtract 4509 from 4769, we get 260.
Include the next digit (6) from the dividend after 260, then repeat: 2606 / 501

On to step 7:
501 can be fit into 2606 5 times, resulting in a remainder of 101.
Record the quotient 5 as the next digit in the result. 
Result so far: 12895.0
The remainder is 101 after subtracting 2505 from 2606.
Take the next digit (5) from the dividend and append it to 101, then repeat: 1015 / 501

On to step 8:
The number 501 fits into 1015 2 times, leaving a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 128952.0
Subtracting 1002 from 1015 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
The number 501 fits into 130 0 times, leaving a remainder of 130.
The next digit of our result is 0. 
Result so far: 128952.0
Subtract 0 from 130 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 10:
1300 divided by 501 is 2 with a remainder of 298.
The number 2 becomes the next digit in our result. 
Result so far: 128952.02
Deduct 1002 from 1300 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Let's proceed to step 11:
501 goes into 2980 5 times with a remainder of 475.
Record the quotient 5 as the next digit in the result. 
Result so far: 128952.025
Deduct 2505 from 2980 and we're left with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Going ahead to step 12:
If we divide 4750 by 501, we get 9 and a remainder of 241.
Put 9 as the next digit of the answer. 
Result so far: 128952.0259
The remainder is 241 after subtracting 4509 from 4750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Moving on to step 13:
2410 divided by 501 is 4 with a remainder of 406.
Record the quotient 4 as the next digit in the result. 
Result so far: 128952.02594
If we take 2004 away from 2410, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Going ahead to step 14:
If we divide 4060 by 501, we get 8 and a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 128952.025948
If we take 4008 away from 4060, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 15:
501 can be fit into 520 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 128952.0259481
If we subtract 501 from 520, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 16:
If we divide 190 by 501, we get 0 and a remainder of 190.
Write down 0 as next digit of the result. 
Result so far: 128952.0259481
Deduct 0 from 190 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

The quotient of the division is 128952.0259481, and the remainder is 1.9e-07.
