18608253 divided by 866 
The aim is to understand the frequency of 866 in 18608253.

Advancing to step 1:
1 divided by 866 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 866

Going ahead to step 2:
18 divided by 866 is 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 866

Step 3:
The number 866 fits into 186 0 times, leaving a remainder of 186.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 186, we end up with 186.
Include the next digit (0) from the dividend after 186, then repeat: 1860 / 866

Going ahead to step 4:
866 goes into 1860 2 times with a remainder of 128.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 128 after subtracting 1732 from 1860.
Grab the next digit (8) from the dividend, add it to 128, then carry on: 1288 / 866

Going ahead to step 5:
The number 866 fits into 1288 1 times, leaving a remainder of 422.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Deduct 866 from 1288 and we're left with 422.
Fetch the next digit (2) from the dividend, attach it to 422 and continue: 4222 / 866

Going ahead to step 6:
866 goes into 4222 4 times with a remainder of 758.
Write down 4 as next digit of the result. 
Result so far: 214.0
Subtract 3464 from 4222 to get 758.
Append the next digit (5) from the dividend to 758 and continue with: 7585 / 866

Let's proceed to step 7:
866 can be fit into 7585 8 times, resulting in a remainder of 657.
Record the quotient 8 as the next digit in the result. 
Result so far: 2148.0
Deduct 6928 from 7585 and we're left with 657.
Include the next digit (3) from the dividend after 657, then repeat: 6573 / 866

Advancing to step 8:
6573 divided by 866 is 7 with a remainder of 511.
The next digit of our result is 7. 
Result so far: 21487.0
If we take 6062 away from 6573, we end up with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Step 9:
When dividing 5110 by 866, we get 5 with a remainder of 780.
The number 5 becomes the next digit in our result. 
Result so far: 21487.5
If we subtract 4330 from 5110, we get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Advancing to step 10:
If we divide 7800 by 866, we get 9 and a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 21487.59
The remainder is 6 after subtracting 7794 from 7800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
The number 866 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 21487.59
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
If we divide 600 by 866, we get 0 and a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 21487.59
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final result is 21487.59 with a remainder of 0.006.
