52408818 divided by 866 
Let's see how many times 866 fits into 52408818.

Step 1:
When dividing 5 by 866, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 866

Step 2:
866 goes into 52 0 times with a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Take the next digit (4) from the dividend and append it to 52, then repeat: 524 / 866

On to step 3:
When dividing 524 by 866, we get 0 with a remainder of 524.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 524 after subtracting 0 from 524.
Bring next digit (0) of the dividend behind the 524 and repeat the process: 5240 / 866

On to step 4:
866 can be fit into 5240 6 times, resulting in a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 5196 from 5240 leaves us with 44.
Bring next digit (8) of the dividend behind the 44 and repeat the process: 448 / 866

Advancing to step 5:
If we divide 448 by 866, we get 0 and a remainder of 448.
The next digit of our result is 0. 
Result so far: 60.0
Deduct 0 from 448 and we're left with 448.
Append the next digit (8) from the dividend to 448 and continue with: 4488 / 866

Let's proceed to step 6:
When dividing 4488 by 866, we get 5 with a remainder of 158.
Put 5 as the next digit of the answer. 
Result so far: 605.0
Subtracting 4330 from 4488 leaves us with 158.
Include the next digit (1) from the dividend after 158, then repeat: 1581 / 866

Moving on to step 7:
866 can be fit into 1581 1 times, resulting in a remainder of 715.
Write down 1 as next digit of the result. 
Result so far: 6051.0
If we subtract 866 from 1581, we get 715.
Grab the next digit (8) from the dividend, add it to 715, then carry on: 7158 / 866

Advancing to step 8:
866 goes into 7158 8 times with a remainder of 230.
Use 8 as the next digit of our solution. 
Result so far: 60518.0
Subtracting 6928 from 7158 leaves us 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.

On to step 9:
2300 divided by 866 is 2 with a remainder of 568.
Record the quotient 2 as the next digit in the result. 
Result so far: 60518.2
Deduct 1732 from 2300 and we're left with 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 10:
866 can be fit into 5680 6 times, resulting in a remainder of 484.
Record the quotient 6 as the next digit in the result. 
Result so far: 60518.26
If we take 5196 away from 5680, we end up with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Step 11:
The number 866 fits into 4840 5 times, leaving a remainder of 510.
The next digit of our result is 5. 
Result so far: 60518.265
If we take 4330 away from 4840, we end up 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.

Step 12:
866 goes into 5100 5 times with a remainder of 770.
Use 5 as the next digit of our solution. 
Result so far: 60518.2655
If we take 4330 away from 5100, we end up with 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 result is 60518.2655 with a remainder of 0.0077.
