54096814 ÷ 866 
Our goal is to divide 54096814 by 866.

Going ahead to step 1:
If we divide 5 by 866, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 866

Advancing to step 2:
866 can be fit into 54 0 times, resulting in a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Include the next digit (0) from the dividend after 54, then repeat: 540 / 866

On to step 3:
866 goes into 540 0 times with a remainder of 540.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 540 leaves us with 540.
Fetch the next digit (9) from the dividend, attach it to 540 and continue: 5409 / 866

Going ahead to step 4:
866 goes into 5409 6 times with a remainder of 213.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 5196 from 5409 to get 213.
Take the next digit (6) from the dividend and append it to 213, then repeat: 2136 / 866

Advancing to step 5:
When dividing 2136 by 866, we get 2 with a remainder of 404.
Write down 2 as next digit of the result. 
Result so far: 62.0
Subtract 1732 from 2136 to get 404.
Take the next digit (8) from the dividend and append it to 404, then repeat: 4048 / 866

Moving on to step 6:
When dividing 4048 by 866, we get 4 with a remainder of 584.
Record the quotient 4 as the next digit in the result. 
Result so far: 624.0
If we take 3464 away from 4048, we end up with 584.
Append the next digit (1) from the dividend to 584 and continue with: 5841 / 866

Let's proceed to step 7:
When dividing 5841 by 866, we get 6 with a remainder of 645.
Write down 6 as next digit of the result. 
Result so far: 6246.0
The remainder is 645 after subtracting 5196 from 5841.
Fetch the next digit (4) from the dividend, attach it to 645 and continue: 6454 / 866

Moving on to step 8:
6454 divided by 866 is 7 with a remainder of 392.
The number 7 becomes the next digit in our result. 
Result so far: 62467.0
Subtract 6062 from 6454 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Let's proceed to step 9:
If we divide 3920 by 866, we get 4 and a remainder of 456.
Record the quotient 4 as the next digit in the result. 
Result so far: 62467.4
The remainder is 456 after subtracting 3464 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Let's proceed to step 10:
When dividing 4560 by 866, we get 5 with a remainder of 230.
The number 5 becomes the next digit in our result. 
Result so far: 62467.45
If we take 4330 away from 4560, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 11:
If we divide 2300 by 866, we get 2 and a remainder of 568.
The number 2 becomes the next digit in our result. 
Result so far: 62467.452
If we subtract 1732 from 2300, we get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Moving on to step 12:
When dividing 5680 by 866, we get 6 with a remainder of 484.
Put 6 as the next digit of the answer. 
Result so far: 62467.4526
The remainder is 484 after subtracting 5196 from 5680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Moving on to step 13:
4840 divided by 866 is 5 with a remainder of 510.
The next digit of our result is 5. 
Result so far: 62467.45265
Subtracting 4330 from 4840 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 14:
If we divide 5100 by 866, we get 5 and a remainder of 770.
The next digit of our result is 5. 
Result so far: 62467.452655
Subtract 4330 from 5100 to get 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

The final outcome is 62467.452655, with a leftover of 7.7e-05.
