Let's divide 8259845 by 266
The aim is to understand the frequency of 266 in 8259845.

Advancing to step 1:
266 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 266

Moving on to step 2:
If we divide 82 by 266, we get 0 and a remainder of 82.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 82, we end up with 82.
Include the next digit (5) from the dividend after 82, then repeat: 825 / 266

Step 3:
825 divided by 266 is 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 798 from 825 to get 27.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 266

Step 4:
The number 266 fits into 279 1 times, leaving a remainder of 13.
The next digit of our result is 1. 
Result so far: 31.0
Subtract 266 from 279 to get 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 266

On to step 5:
The number 266 fits into 138 0 times, leaving a remainder of 138.
Use 0 as the next digit of our solution. 
Result so far: 310.0
The remainder is 138 after subtracting 0 from 138.
Fetch the next digit (4) from the dividend, attach it to 138 and continue: 1384 / 266

Going ahead to step 6:
If we divide 1384 by 266, we get 5 and a remainder of 54.
Write down 5 as next digit of the result. 
Result so far: 3105.0
If we take 1330 away from 1384, we end up with 54.
Bring next digit (5) of the dividend behind the 54 and repeat the process: 545 / 266

Going ahead to step 7:
If we divide 545 by 266, we get 2 and a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 31052.0
The remainder is 13 after subtracting 532 from 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 8:
266 goes into 130 0 times with a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 31052.0
If we subtract 0 from 130, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 9:
266 can be fit into 1300 4 times, resulting in a remainder of 236.
Put 4 as the next digit of the answer. 
Result so far: 31052.04
If we subtract 1064 from 1300, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Moving on to step 10:
266 can be fit into 2360 8 times, resulting in a remainder of 232.
Put 8 as the next digit of the answer. 
Result so far: 31052.048
If we subtract 2128 from 2360, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 11:
If we divide 2320 by 266, we get 8 and a remainder of 192.
The number 8 becomes the next digit in our result. 
Result so far: 31052.0488
If we take 2128 away from 2320, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The final result is 31052.0488 with a remainder of 0.00192.
