9872138 ÷ 265 
The aim is to understand the frequency of 265 in 9872138.

Advancing to step 1:
265 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 265

Advancing to step 2:
265 goes into 98 0 times with a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Grab the next digit (7) from the dividend, add it to 98, then carry on: 987 / 265

Advancing to step 3:
The number 265 fits into 987 3 times, leaving a remainder of 192.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 192 after subtracting 795 from 987.
Include the next digit (2) from the dividend after 192, then repeat: 1922 / 265

Let's proceed to step 4:
If we divide 1922 by 265, we get 7 and a remainder of 67.
Put 7 as the next digit of the answer. 
Result so far: 37.0
The remainder is 67 after subtracting 1855 from 1922.
Take the next digit (1) from the dividend and append it to 67, then repeat: 671 / 265

Moving on to step 5:
265 goes into 671 2 times with a remainder of 141.
Record the quotient 2 as the next digit in the result. 
Result so far: 372.0
Deduct 530 from 671 and we're left with 141.
Take the next digit (3) from the dividend and append it to 141, then repeat: 1413 / 265

Advancing to step 6:
When dividing 1413 by 265, we get 5 with a remainder of 88.
Use 5 as the next digit of our solution. 
Result so far: 3725.0
Deduct 1325 from 1413 and we're left with 88.
Grab the next digit (8) from the dividend, add it to 88, then carry on: 888 / 265

Step 7:
265 goes into 888 3 times with a remainder of 93.
The next digit of our result is 3. 
Result so far: 37253.0
If we subtract 795 from 888, we get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Moving on to step 8:
265 goes into 930 3 times with a remainder of 135.
The next digit of our result is 3. 
Result so far: 37253.3
Subtract 795 from 930 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 9:
265 can be fit into 1350 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 37253.35
Subtract 1325 from 1350 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
250 divided by 265 is 0 with a remainder of 250.
The next digit of our result is 0. 
Result so far: 37253.35
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 11:
265 can be fit into 2500 9 times, resulting in a remainder of 115.
Record the quotient 9 as the next digit in the result. 
Result so far: 37253.3509
Subtracting 2385 from 2500 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 12:
The number 265 fits into 1150 4 times, leaving a remainder of 90.
The next digit of our result is 4. 
Result so far: 37253.35094
Subtract 1060 from 1150 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 13:
900 divided by 265 is 3 with a remainder of 105.
Write down 3 as next digit of the result. 
Result so far: 37253.350943
The remainder is 105 after subtracting 795 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 14:
265 goes into 1050 3 times with a remainder of 255.
Put 3 as the next digit of the answer. 
Result so far: 37253.3509433
Subtracting 795 from 1050 leaves us 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.

Our division results in 37253.3509433 with a remaining 2.55e-06.
