66565320 ÷ 301 
The aim is to understand the frequency of 301 in 66565320.

Going ahead to step 1:
301 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 301

Going ahead to step 2:
301 can be fit into 66 0 times, resulting in a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Include the next digit (5) from the dividend after 66, then repeat: 665 / 301

On to step 3:
301 goes into 665 2 times with a remainder of 63.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 602 from 665, we get 63.
Take the next digit (6) from the dividend and append it to 63, then repeat: 636 / 301

Advancing to step 4:
If we divide 636 by 301, we get 2 and a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
The remainder is 34 after subtracting 602 from 636.
Append the next digit (5) from the dividend to 34 and continue with: 345 / 301

Step 5:
345 divided by 301 is 1 with a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 221.0
Deduct 301 from 345 and we're left with 44.
Append the next digit (3) from the dividend to 44 and continue with: 443 / 301

Moving on to step 6:
When dividing 443 by 301, we get 1 with a remainder of 142.
Record the quotient 1 as the next digit in the result. 
Result so far: 2211.0
Subtracting 301 from 443 leaves us with 142.
Append the next digit (2) from the dividend to 142 and continue with: 1422 / 301

Advancing to step 7:
301 can be fit into 1422 4 times, resulting in a remainder of 218.
The next digit of our result is 4. 
Result so far: 22114.0
If we subtract 1204 from 1422, we get 218.
Append the next digit (0) from the dividend to 218 and continue with: 2180 / 301

On to step 8:
When dividing 2180 by 301, we get 7 with a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 221147.0
Subtract 2107 from 2180 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 9:
If we divide 730 by 301, we get 2 and a remainder of 128.
The number 2 becomes the next digit in our result. 
Result so far: 221147.2
Subtract 602 from 730 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 10:
301 can be fit into 1280 4 times, resulting in a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 221147.24
Subtracting 1204 from 1280 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
The number 301 fits into 760 2 times, leaving a remainder of 158.
The number 2 becomes the next digit in our result. 
Result so far: 221147.242
Subtract 602 from 760 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 12:
301 can be fit into 1580 5 times, resulting in a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 221147.2425
If we subtract 1505 from 1580, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 13:
301 can be fit into 750 2 times, resulting in a remainder of 148.
Use 2 as the next digit of our solution. 
Result so far: 221147.24252
Subtract 602 from 750 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 14:
When dividing 1480 by 301, we get 4 with a remainder of 276.
The next digit of our result is 4. 
Result so far: 221147.242524
Subtract 1204 from 1480 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Let's proceed to step 15:
When dividing 2760 by 301, we get 9 with a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 221147.2425249
Subtracting 2709 from 2760 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 16:
When dividing 510 by 301, we get 1 with a remainder of 209.
Use 1 as the next digit of our solution. 
Result so far: 221147.24252491
If we subtract 301 from 510, we get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Our division results in 221147.24252491 with a remaining 2.09e-07.
