Let's divide 42309088 by 866
Our goal is to divide 42309088 by 866.

Going ahead to step 1:
When dividing 4 by 866, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 866

Let's proceed to step 2:
The number 866 fits into 42 0 times, leaving a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 866

Going ahead to step 3:
The number 866 fits into 423 0 times, leaving a remainder of 423.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 423, we end up with 423.
Grab the next digit (0) from the dividend, add it to 423, then carry on: 4230 / 866

On to step 4:
When dividing 4230 by 866, we get 4 with a remainder of 766.
The next digit of our result is 4. 
Result so far: 4.0
If we take 3464 away from 4230, we end up with 766.
Grab the next digit (9) from the dividend, add it to 766, then carry on: 7669 / 866

Advancing to step 5:
7669 divided by 866 is 8 with a remainder of 741.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Subtracting 6928 from 7669 leaves us with 741.
Include the next digit (0) from the dividend after 741, then repeat: 7410 / 866

Going ahead to step 6:
866 goes into 7410 8 times with a remainder of 482.
Use 8 as the next digit of our solution. 
Result so far: 488.0
Deduct 6928 from 7410 and we're left with 482.
Fetch the next digit (8) from the dividend, attach it to 482 and continue: 4828 / 866

Going ahead to step 7:
866 can be fit into 4828 5 times, resulting in a remainder of 498.
The number 5 becomes the next digit in our result. 
Result so far: 4885.0
Deduct 4330 from 4828 and we're left with 498.
Bring next digit (8) of the dividend behind the 498 and repeat the process: 4988 / 866

Going ahead to step 8:
If we divide 4988 by 866, we get 5 and a remainder of 658.
Use 5 as the next digit of our solution. 
Result so far: 48855.0
Deduct 4330 from 4988 and we're left with 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Going ahead to step 9:
866 can be fit into 6580 7 times, resulting in a remainder of 518.
Use 7 as the next digit of our solution. 
Result so far: 48855.7
Subtracting 6062 from 6580 leaves us with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Moving on to step 10:
If we divide 5180 by 866, we get 5 and a remainder of 850.
Put 5 as the next digit of the answer. 
Result so far: 48855.75
Deduct 4330 from 5180 and we're left with 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

Moving on to step 11:
866 can be fit into 8500 9 times, resulting in a remainder of 706.
Write down 9 as next digit of the result. 
Result so far: 48855.759
The remainder is 706 after subtracting 7794 from 8500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Moving on to step 12:
If we divide 7060 by 866, we get 8 and a remainder of 132.
Use 8 as the next digit of our solution. 
Result so far: 48855.7598
Subtracting 6928 from 7060 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 13:
866 goes into 1320 1 times with a remainder of 454.
Record the quotient 1 as the next digit in the result. 
Result so far: 48855.75981
If we subtract 866 from 1320, we get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Let's proceed to step 14:
4540 divided by 866 is 5 with a remainder of 210.
Use 5 as the next digit of our solution. 
Result so far: 48855.759815
Subtracting 4330 from 4540 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 15:
866 can be fit into 2100 2 times, resulting in a remainder of 368.
Put 2 as the next digit of the answer. 
Result so far: 48855.7598152
Subtracting 1732 from 2100 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 16:
866 can be fit into 3680 4 times, resulting in a remainder of 216.
Write down 4 as next digit of the result. 
Result so far: 48855.75981524
The remainder is 216 after subtracting 3464 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

In conclusion, the division gives 48855.75981524 with a balance of 2.16e-07.
