We're dividing 16618951 by 265 
The aim is to understand the frequency of 265 in 16618951.

Step 1:
If we divide 1 by 265, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 265

On to step 2:
265 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 265

On to step 3:
When dividing 166 by 265, we get 0 with a remainder of 166.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 166 to get 166.
Bring next digit (1) of the dividend behind the 166 and repeat the process: 1661 / 265

Advancing to step 4:
265 goes into 1661 6 times with a remainder of 71.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 1590 from 1661 and we're left with 71.
Grab the next digit (8) from the dividend, add it to 71, then carry on: 718 / 265

Moving on to step 5:
265 can be fit into 718 2 times, resulting in a remainder of 188.
Write down 2 as next digit of the result. 
Result so far: 62.0
Subtract 530 from 718 to get 188.
Append the next digit (9) from the dividend to 188 and continue with: 1889 / 265

Step 6:
If we divide 1889 by 265, we get 7 and a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 627.0
If we take 1855 away from 1889, we end up with 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 265

Step 7:
When dividing 345 by 265, we get 1 with a remainder of 80.
Write down 1 as next digit of the result. 
Result so far: 6271.0
Subtracting 265 from 345 leaves us with 80.
Fetch the next digit (1) from the dividend, attach it to 80 and continue: 801 / 265

Moving on to step 8:
265 can be fit into 801 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 62713.0
Subtract 795 from 801 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
When dividing 60 by 265, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 62713.0
Subtracting 0 from 60 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 10:
When dividing 600 by 265, we get 2 with a remainder of 70.
Use 2 as the next digit of our solution. 
Result so far: 62713.02
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.

Going ahead to step 11:
265 can be fit into 700 2 times, resulting in a remainder of 170.
The number 2 becomes the next digit in our result. 
Result so far: 62713.022
If we subtract 530 from 700, 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.

The final result is 62713.022 with a remainder of 0.017.
