We look at the division of 13890913 by 265 
The aim is to understand the frequency of 265 in 13890913.

Going ahead to step 1:
265 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 265

Advancing to step 2:
13 divided by 265 is 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 265

Let's proceed to step 3:
265 can be fit into 138 0 times, resulting in a remainder of 138.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 138 after subtracting 0 from 138.
Append the next digit (9) from the dividend to 138 and continue with: 1389 / 265

Step 4:
The number 265 fits into 1389 5 times, leaving a remainder of 64.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 1325 from 1389 and we're left with 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 265

Moving on to step 5:
265 can be fit into 640 2 times, resulting in a remainder of 110.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Deduct 530 from 640 and we're left with 110.
Include the next digit (9) from the dividend after 110, then repeat: 1109 / 265

Advancing to step 6:
265 goes into 1109 4 times with a remainder of 49.
Record the quotient 4 as the next digit in the result. 
Result so far: 524.0
Subtracting 1060 from 1109 leaves us with 49.
Grab the next digit (1) from the dividend, add it to 49, then carry on: 491 / 265

Moving on to step 7:
When dividing 491 by 265, we get 1 with a remainder of 226.
Write down 1 as next digit of the result. 
Result so far: 5241.0
Subtracting 265 from 491 leaves us with 226.
Include the next digit (3) from the dividend after 226, then repeat: 2263 / 265

Moving on to step 8:
265 can be fit into 2263 8 times, resulting in a remainder of 143.
The number 8 becomes the next digit in our result. 
Result so far: 52418.0
Deduct 2120 from 2263 and we're left with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 9:
1430 divided by 265 is 5 with a remainder of 105.
Record the quotient 5 as the next digit in the result. 
Result so far: 52418.5
Subtracting 1325 from 1430 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 10:
When dividing 1050 by 265, we get 3 with a remainder of 255.
Write down 3 as next digit of the result. 
Result so far: 52418.53
Deduct 795 from 1050 and we're left with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 11:
265 goes into 2550 9 times with a remainder of 165.
The number 9 becomes the next digit in our result. 
Result so far: 52418.539
If we subtract 2385 from 2550, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 12:
If we divide 1650 by 265, we get 6 and a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 52418.5396
Subtracting 1590 from 1650 leaves us 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.

Advancing to step 13:
600 divided by 265 is 2 with a remainder of 70.
Record the quotient 2 as the next digit in the result. 
Result so far: 52418.53962
Subtract 530 from 600 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 14:
265 goes into 700 2 times with a remainder of 170.
Put 2 as the next digit of the answer. 
Result so far: 52418.539622
Subtract 530 from 700 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

After the division, we end up with 52418.539622 and a remainder of 1.7e-05.
