64968336 divided by 820 
The aim is to understand the frequency of 820 in 64968336.

Step 1:
820 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 820

On to step 2:
820 can be fit into 64 0 times, resulting in a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Bring next digit (9) of the dividend behind the 64 and repeat the process: 649 / 820

Let's proceed to step 3:
When dividing 649 by 820, we get 0 with a remainder of 649.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 649 to get 649.
Bring next digit (6) of the dividend behind the 649 and repeat the process: 6496 / 820

Going ahead to step 4:
820 can be fit into 6496 7 times, resulting in a remainder of 756.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 5740 from 6496 to get 756.
Include the next digit (8) from the dividend after 756, then repeat: 7568 / 820

Advancing to step 5:
If we divide 7568 by 820, we get 9 and a remainder of 188.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
Deduct 7380 from 7568 and we're left with 188.
Fetch the next digit (3) from the dividend, attach it to 188 and continue: 1883 / 820

Going ahead to step 6:
820 can be fit into 1883 2 times, resulting in a remainder of 243.
The number 2 becomes the next digit in our result. 
Result so far: 792.0
Subtracting 1640 from 1883 leaves us with 243.
Append the next digit (3) from the dividend to 243 and continue with: 2433 / 820

Going ahead to step 7:
2433 divided by 820 is 2 with a remainder of 793.
Put 2 as the next digit of the answer. 
Result so far: 7922.0
Subtracting 1640 from 2433 leaves us with 793.
Fetch the next digit (6) from the dividend, attach it to 793 and continue: 7936 / 820

Step 8:
If we divide 7936 by 820, we get 9 and a remainder of 556.
The number 9 becomes the next digit in our result. 
Result so far: 79229.0
Subtracting 7380 from 7936 leaves us with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Moving on to step 9:
When dividing 5560 by 820, we get 6 with a remainder of 640.
Use 6 as the next digit of our solution. 
Result so far: 79229.6
The remainder is 640 after subtracting 4920 from 5560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 10:
The number 820 fits into 6400 7 times, leaving a remainder of 660.
Put 7 as the next digit of the answer. 
Result so far: 79229.67
The remainder is 660 after subtracting 5740 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Step 11:
820 goes into 6600 8 times with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 79229.678
If we take 6560 away from 6600, 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.

On to step 12:
820 goes into 400 0 times with a remainder of 400.
The next digit of our result is 0. 
Result so far: 79229.678
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 13:
820 goes into 4000 4 times with a remainder of 720.
The next digit of our result is 4. 
Result so far: 79229.67804
Deduct 3280 from 4000 and we're left with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Going ahead to step 14:
820 can be fit into 7200 8 times, resulting in a remainder of 640.
Put 8 as the next digit of the answer. 
Result so far: 79229.678048
The remainder is 640 after subtracting 6560 from 7200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 15:
When dividing 6400 by 820, we get 7 with a remainder of 660.
The number 7 becomes the next digit in our result. 
Result so far: 79229.6780487
If we subtract 5740 from 6400, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 16:
820 goes into 6600 8 times with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 79229.67804878
If we take 6560 away from 6600, 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.

The final result is 79229.67804878 with a remainder of 4e-08.
