We're dividing 86263453 by 265 
The aim is to understand the frequency of 265 in 86263453.

Step 1:
265 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 265

Step 2:
When dividing 86 by 265, we get 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Take the next digit (2) from the dividend and append it to 86, then repeat: 862 / 265

Step 3:
265 can be fit into 862 3 times, resulting in a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 795 away from 862, we end up with 67.
Grab the next digit (6) from the dividend, add it to 67, then carry on: 676 / 265

Let's proceed to step 4:
265 can be fit into 676 2 times, resulting in a remainder of 146.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Deduct 530 from 676 and we're left with 146.
Take the next digit (3) from the dividend and append it to 146, then repeat: 1463 / 265

Moving on to step 5:
265 goes into 1463 5 times with a remainder of 138.
Write down 5 as next digit of the result. 
Result so far: 325.0
If we subtract 1325 from 1463, we get 138.
Grab the next digit (4) from the dividend, add it to 138, then carry on: 1384 / 265

Let's proceed to step 6:
When dividing 1384 by 265, we get 5 with a remainder of 59.
The number 5 becomes the next digit in our result. 
Result so far: 3255.0
If we take 1325 away from 1384, we end up with 59.
Fetch the next digit (5) from the dividend, attach it to 59 and continue: 595 / 265

On to step 7:
If we divide 595 by 265, we get 2 and a remainder of 65.
Record the quotient 2 as the next digit in the result. 
Result so far: 32552.0
Subtracting 530 from 595 leaves us with 65.
Include the next digit (3) from the dividend after 65, then repeat: 653 / 265

Moving on to step 8:
265 can be fit into 653 2 times, resulting in a remainder of 123.
Write down 2 as next digit of the result. 
Result so far: 325522.0
If we take 530 away from 653, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 9:
265 goes into 1230 4 times with a remainder of 170.
The next digit of our result is 4. 
Result so far: 325522.4
If we subtract 1060 from 1230, we 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.

Advancing to step 10:
The number 265 fits into 1700 6 times, leaving a remainder of 110.
Record the quotient 6 as the next digit in the result. 
Result so far: 325522.46
Deduct 1590 from 1700 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 11:
265 can be fit into 1100 4 times, resulting in a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 325522.464
Subtracting 1060 from 1100 leaves us 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.

Going ahead to step 12:
400 divided by 265 is 1 with a remainder of 135.
The next digit of our result is 1. 
Result so far: 325522.4641
The remainder is 135 after subtracting 265 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 13:
If we divide 1350 by 265, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 325522.46415
If we take 1325 away from 1350, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 14:
If we divide 250 by 265, we get 0 and a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 325522.46415
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 15:
The number 265 fits into 2500 9 times, leaving a remainder of 115.
Record the quotient 9 as the next digit in the result. 
Result so far: 325522.4641509
The remainder is 115 after subtracting 2385 from 2500.
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 16:
If we divide 1150 by 265, we get 4 and a remainder of 90.
The next digit of our result is 4. 
Result so far: 325522.46415094
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.

After the division, we end up with 325522.46415094 and a remainder of 9e-08.
