We're dividing 38889243 by 866 
Our goal is to divide 38889243 by 866.

Moving on to step 1:
When dividing 3 by 866, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 866

Step 2:
The number 866 fits into 38 0 times, leaving a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Fetch the next digit (8) from the dividend, attach it to 38 and continue: 388 / 866

Moving on to step 3:
866 goes into 388 0 times with a remainder of 388.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 388 to get 388.
Take the next digit (8) from the dividend and append it to 388, then repeat: 3888 / 866

Going ahead to step 4:
3888 divided by 866 is 4 with a remainder of 424.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 3464 from 3888 and we're left with 424.
Take the next digit (9) from the dividend and append it to 424, then repeat: 4249 / 866

Moving on to step 5:
The number 866 fits into 4249 4 times, leaving a remainder of 785.
The next digit of our result is 4. 
Result so far: 44.0
Subtract 3464 from 4249 to get 785.
Append the next digit (2) from the dividend to 785 and continue with: 7852 / 866

Moving on to step 6:
866 can be fit into 7852 9 times, resulting in a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 449.0
If we take 7794 away from 7852, we end up with 58.
Take the next digit (4) from the dividend and append it to 58, then repeat: 584 / 866

On to step 7:
866 can be fit into 584 0 times, resulting in a remainder of 584.
Use 0 as the next digit of our solution. 
Result so far: 4490.0
Subtracting 0 from 584 leaves us with 584.
Include the next digit (3) from the dividend after 584, then repeat: 5843 / 866

Moving on to step 8:
When dividing 5843 by 866, we get 6 with a remainder of 647.
Write down 6 as next digit of the result. 
Result so far: 44906.0
Subtract 5196 from 5843 to get 647.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

On to step 9:
866 can be fit into 6470 7 times, resulting in a remainder of 408.
Use 7 as the next digit of our solution. 
Result so far: 44906.7
If we subtract 6062 from 6470, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Step 10:
866 can be fit into 4080 4 times, resulting in a remainder of 616.
The number 4 becomes the next digit in our result. 
Result so far: 44906.74
If we subtract 3464 from 4080, we get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Moving on to step 11:
If we divide 6160 by 866, we get 7 and a remainder of 98.
Use 7 as the next digit of our solution. 
Result so far: 44906.747
If we take 6062 away from 6160, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 12:
866 can be fit into 980 1 times, resulting in a remainder of 114.
Put 1 as the next digit of the answer. 
Result so far: 44906.7471
Subtracting 866 from 980 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 13:
When dividing 1140 by 866, we get 1 with a remainder of 274.
Use 1 as the next digit of our solution. 
Result so far: 44906.74711
If we take 866 away from 1140, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

The final outcome is 44906.74711, with a leftover of 0.000274.
