We divide 45030844 by 866
The aim is to understand the frequency of 866 in 45030844.

Let's proceed to step 1:
When dividing 4 by 866, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 866

Let's proceed to step 2:
866 can be fit into 45 0 times, resulting in a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Bring next digit (0) of the dividend behind the 45 and repeat the process: 450 / 866

Moving on to step 3:
450 divided by 866 is 0 with a remainder of 450.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 450 and we're left with 450.
Include the next digit (3) from the dividend after 450, then repeat: 4503 / 866

Moving on to step 4:
The number 866 fits into 4503 5 times, leaving a remainder of 173.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 4330 from 4503 to get 173.
Fetch the next digit (0) from the dividend, attach it to 173 and continue: 1730 / 866

Moving on to step 5:
1730 divided by 866 is 1 with a remainder of 864.
Use 1 as the next digit of our solution. 
Result so far: 51.0
Subtract 866 from 1730 to get 864.
Fetch the next digit (8) from the dividend, attach it to 864 and continue: 8648 / 866

Moving on to step 6:
866 goes into 8648 9 times with a remainder of 854.
The next digit of our result is 9. 
Result so far: 519.0
The remainder is 854 after subtracting 7794 from 8648.
Take the next digit (4) from the dividend and append it to 854, then repeat: 8544 / 866

Let's proceed to step 7:
When dividing 8544 by 866, we get 9 with a remainder of 750.
The next digit of our result is 9. 
Result so far: 5199.0
Subtracting 7794 from 8544 leaves us with 750.
Bring next digit (4) of the dividend behind the 750 and repeat the process: 7504 / 866

Let's proceed to step 8:
If we divide 7504 by 866, we get 8 and a remainder of 576.
Put 8 as the next digit of the answer. 
Result so far: 51998.0
If we subtract 6928 from 7504, we get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Step 9:
When dividing 5760 by 866, we get 6 with a remainder of 564.
Put 6 as the next digit of the answer. 
Result so far: 51998.6
The remainder is 564 after subtracting 5196 from 5760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Going ahead to step 10:
The number 866 fits into 5640 6 times, leaving a remainder of 444.
The next digit of our result is 6. 
Result so far: 51998.66
The remainder is 444 after subtracting 5196 from 5640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

After the division, we end up with 51998.66 and a remainder of 0.444.
