We're dividing 26662990 by 866 
The aim is to understand the frequency of 866 in 26662990.

Let's proceed to step 1:
866 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 866

Going ahead to step 2:
If we divide 26 by 866, we get 0 and a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Take the next digit (6) from the dividend and append it to 26, then repeat: 266 / 866

On to step 3:
866 goes into 266 0 times with a remainder of 266.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 266 leaves us with 266.
Grab the next digit (6) from the dividend, add it to 266, then carry on: 2666 / 866

Let's proceed to step 4:
2666 divided by 866 is 3 with a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 2598 from 2666 and we're left with 68.
Grab the next digit (2) from the dividend, add it to 68, then carry on: 682 / 866

Let's proceed to step 5:
When dividing 682 by 866, we get 0 with a remainder of 682.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we subtract 0 from 682, we get 682.
Include the next digit (9) from the dividend after 682, then repeat: 6829 / 866

Moving on to step 6:
6829 divided by 866 is 7 with a remainder of 767.
Write down 7 as next digit of the result. 
Result so far: 307.0
Subtracting 6062 from 6829 leaves us with 767.
Fetch the next digit (9) from the dividend, attach it to 767 and continue: 7679 / 866

Moving on to step 7:
The number 866 fits into 7679 8 times, leaving a remainder of 751.
The number 8 becomes the next digit in our result. 
Result so far: 3078.0
The remainder is 751 after subtracting 6928 from 7679.
Fetch the next digit (0) from the dividend, attach it to 751 and continue: 7510 / 866

On to step 8:
When dividing 7510 by 866, we get 8 with a remainder of 582.
Write down 8 as next digit of the result. 
Result so far: 30788.0
Subtracting 6928 from 7510 leaves us with 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Step 9:
The number 866 fits into 5820 6 times, leaving a remainder of 624.
The next digit of our result is 6. 
Result so far: 30788.6
Subtracting 5196 from 5820 leaves us with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

On to step 10:
If we divide 6240 by 866, we get 7 and a remainder of 178.
Write down 7 as next digit of the result. 
Result so far: 30788.67
The remainder is 178 after subtracting 6062 from 6240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Advancing to step 11:
866 can be fit into 1780 2 times, resulting in a remainder of 48.
The next digit of our result is 2. 
Result so far: 30788.672
Deduct 1732 from 1780 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
866 can be fit into 480 0 times, resulting in a remainder of 480.
The next digit of our result is 0. 
Result so far: 30788.672
If we take 0 away from 480, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 13:
If we divide 4800 by 866, we get 5 and a remainder of 470.
Record the quotient 5 as the next digit in the result. 
Result so far: 30788.67205
Subtract 4330 from 4800 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 14:
4700 divided by 866 is 5 with a remainder of 370.
The next digit of our result is 5. 
Result so far: 30788.672055
If we subtract 4330 from 4700, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

In conclusion, the division gives 30788.672055 with a balance of 3.7e-05.
