63609645 ÷ 265 
The aim is to understand the frequency of 265 in 63609645.

Step 1:
When dividing 6 by 265, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 265

Going ahead to step 2:
265 goes into 63 0 times with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Fetch the next digit (6) from the dividend, attach it to 63 and continue: 636 / 265

Advancing to step 3:
The number 265 fits into 636 2 times, leaving a remainder of 106.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 530 from 636, we get 106.
Grab the next digit (0) from the dividend, add it to 106, then carry on: 1060 / 265

On to step 4:
265 can be fit into 1060 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we take 1060 away from 1060, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 265

Going ahead to step 5:
If we divide 9 by 265, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 240.0
If we subtract 0 from 9, we get 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 265

Step 6:
When dividing 96 by 265, we get 0 with a remainder of 96.
The number 0 becomes the next digit in our result. 
Result so far: 2400.0
Deduct 0 from 96 and we're left with 96.
Fetch the next digit (4) from the dividend, attach it to 96 and continue: 964 / 265

Let's proceed to step 7:
When dividing 964 by 265, we get 3 with a remainder of 169.
Use 3 as the next digit of our solution. 
Result so far: 24003.0
Subtract 795 from 964 to get 169.
Grab the next digit (5) from the dividend, add it to 169, then carry on: 1695 / 265

Let's proceed to step 8:
If we divide 1695 by 265, we get 6 and a remainder of 105.
Write down 6 as next digit of the result. 
Result so far: 240036.0
Deduct 1590 from 1695 and we're left 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.

Moving on to step 9:
If we divide 1050 by 265, we get 3 and a remainder of 255.
Use 3 as the next digit of our solution. 
Result so far: 240036.3
If we take 795 away from 1050, we end up 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.

Step 10:
265 can be fit into 2550 9 times, resulting in a remainder of 165.
The next digit of our result is 9. 
Result so far: 240036.39
The remainder is 165 after subtracting 2385 from 2550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 11:
If we divide 1650 by 265, we get 6 and a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 240036.396
If we take 1590 away from 1650, we end up 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.

Going ahead to step 12:
If we divide 600 by 265, we get 2 and a remainder of 70.
Write down 2 as next digit of the result. 
Result so far: 240036.3962
Subtracting 530 from 600 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 13:
700 divided by 265 is 2 with a remainder of 170.
Record the quotient 2 as the next digit in the result. 
Result so far: 240036.39622
The remainder is 170 after subtracting 530 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The quotient of the division is 240036.39622, and the remainder is 0.00017.
