We're dividing 1382766 by 266 
The aim is to understand the frequency of 266 in 1382766.

On to step 1:
The number 266 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 266

On to step 2:
266 can be fit into 13 0 times, resulting in a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 266

On to step 3:
138 divided by 266 is 0 with a remainder of 138.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 138, we get 138.
Append the next digit (2) from the dividend to 138 and continue with: 1382 / 266

Advancing to step 4:
266 can be fit into 1382 5 times, resulting in a remainder of 52.
The next digit of our result is 5. 
Result so far: 5.0
If we take 1330 away from 1382, we end up with 52.
Fetch the next digit (7) from the dividend, attach it to 52 and continue: 527 / 266

Going ahead to step 5:
The number 266 fits into 527 1 times, leaving a remainder of 261.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
If we subtract 266 from 527, we get 261.
Bring next digit (6) of the dividend behind the 261 and repeat the process: 2616 / 266

On to step 6:
The number 266 fits into 2616 9 times, leaving a remainder of 222.
Write down 9 as next digit of the result. 
Result so far: 519.0
If we subtract 2394 from 2616, we get 222.
Take the next digit (6) from the dividend and append it to 222, then repeat: 2226 / 266

Let's proceed to step 7:
When dividing 2226 by 266, we get 8 with a remainder of 98.
Record the quotient 8 as the next digit in the result. 
Result so far: 5198.0
The remainder is 98 after subtracting 2128 from 2226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 8:
The number 266 fits into 980 3 times, leaving a remainder of 182.
Use 3 as the next digit of our solution. 
Result so far: 5198.3
If we subtract 798 from 980, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 9:
If we divide 1820 by 266, we get 6 and a remainder of 224.
The next digit of our result is 6. 
Result so far: 5198.36
Deduct 1596 from 1820 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 10:
266 can be fit into 2240 8 times, resulting in a remainder of 112.
The next digit of our result is 8. 
Result so far: 5198.368
Deduct 2128 from 2240 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 11:
If we divide 1120 by 266, we get 4 and a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 5198.3684
Deduct 1064 from 1120 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 12:
The number 266 fits into 560 2 times, leaving a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 5198.36842
Subtracting 532 from 560 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
280 divided by 266 is 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 5198.368421
Subtract 266 from 280 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 14:
The number 266 fits into 140 0 times, leaving a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 5198.368421
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 15:
266 goes into 1400 5 times with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 5198.36842105
Subtracting 1330 from 1400 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.

In conclusion, the division gives 5198.36842105 with a balance of 7e-08.
