We look at the division of 66594406 by 265 
The aim is to understand the frequency of 265 in 66594406.

Step 1:
The number 265 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 265

Step 2:
66 divided by 265 is 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 265

Advancing to step 3:
If we divide 665 by 265, we get 2 and a remainder of 135.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 530 from 665 to get 135.
Bring next digit (9) of the dividend behind the 135 and repeat the process: 1359 / 265

Moving on to step 4:
The number 265 fits into 1359 5 times, leaving a remainder of 34.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Deduct 1325 from 1359 and we're left with 34.
Grab the next digit (4) from the dividend, add it to 34, then carry on: 344 / 265

Let's proceed to step 5:
If we divide 344 by 265, we get 1 and a remainder of 79.
The next digit of our result is 1. 
Result so far: 251.0
Subtract 265 from 344 to get 79.
Include the next digit (4) from the dividend after 79, then repeat: 794 / 265

Step 6:
The number 265 fits into 794 2 times, leaving a remainder of 264.
Record the quotient 2 as the next digit in the result. 
Result so far: 2512.0
Subtracting 530 from 794 leaves us with 264.
Fetch the next digit (0) from the dividend, attach it to 264 and continue: 2640 / 265

Advancing to step 7:
2640 divided by 265 is 9 with a remainder of 255.
Put 9 as the next digit of the answer. 
Result so far: 25129.0
If we take 2385 away from 2640, we end up with 255.
Include the next digit (6) from the dividend after 255, then repeat: 2556 / 265

Going ahead to step 8:
265 goes into 2556 9 times with a remainder of 171.
Write down 9 as next digit of the result. 
Result so far: 251299.0
Deduct 2385 from 2556 and we're left with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Let's proceed to step 9:
If we divide 1710 by 265, we get 6 and a remainder of 120.
Record the quotient 6 as the next digit in the result. 
Result so far: 251299.6
Deduct 1590 from 1710 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 10:
If we divide 1200 by 265, we get 4 and a remainder of 140.
The number 4 becomes the next digit in our result. 
Result so far: 251299.64
Subtract 1060 from 1200 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
265 goes into 1400 5 times with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 251299.645
If we take 1325 away from 1400, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 12:
265 can be fit into 750 2 times, resulting in a remainder of 220.
Use 2 as the next digit of our solution. 
Result so far: 251299.6452
The remainder is 220 after subtracting 530 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 13:
265 can be fit into 2200 8 times, resulting in a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 251299.64528
Subtract 2120 from 2200 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
265 can be fit into 800 3 times, resulting in a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 251299.645283
If we take 795 away from 800, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 15:
If we divide 50 by 265, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 251299.645283
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 16:
If we divide 500 by 265, we get 1 and a remainder of 235.
Put 1 as the next digit of the answer. 
Result so far: 251299.64528301
If we subtract 265 from 500, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Our division results in 251299.64528301 with a remaining 2.35e-07.
