We look at the division of 42380656 by 966 
Our goal is to divide 42380656 by 966.

On to step 1:
4 divided by 966 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 966

Advancing to step 2:
If we divide 42 by 966, we get 0 and a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 966

On to step 3:
If we divide 423 by 966, we get 0 and a remainder of 423.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 423 after subtracting 0 from 423.
Bring next digit (8) of the dividend behind the 423 and repeat the process: 4238 / 966

Advancing to step 4:
If we divide 4238 by 966, we get 4 and a remainder of 374.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 374 after subtracting 3864 from 4238.
Append the next digit (0) from the dividend to 374 and continue with: 3740 / 966

Going ahead to step 5:
When dividing 3740 by 966, we get 3 with a remainder of 842.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtract 2898 from 3740 to get 842.
Take the next digit (6) from the dividend and append it to 842, then repeat: 8426 / 966

Step 6:
When dividing 8426 by 966, we get 8 with a remainder of 698.
The number 8 becomes the next digit in our result. 
Result so far: 438.0
The remainder is 698 after subtracting 7728 from 8426.
Append the next digit (5) from the dividend to 698 and continue with: 6985 / 966

Going ahead to step 7:
966 can be fit into 6985 7 times, resulting in a remainder of 223.
The next digit of our result is 7. 
Result so far: 4387.0
Subtracting 6762 from 6985 leaves us with 223.
Fetch the next digit (6) from the dividend, attach it to 223 and continue: 2236 / 966

On to step 8:
If we divide 2236 by 966, we get 2 and a remainder of 304.
The next digit of our result is 2. 
Result so far: 43872.0
Deduct 1932 from 2236 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 9:
966 can be fit into 3040 3 times, resulting in a remainder of 142.
Use 3 as the next digit of our solution. 
Result so far: 43872.3
If we take 2898 away from 3040, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 10:
If we divide 1420 by 966, we get 1 and a remainder of 454.
The next digit of our result is 1. 
Result so far: 43872.31
If we take 966 away from 1420, we end up with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

On to step 11:
The number 966 fits into 4540 4 times, leaving a remainder of 676.
Put 4 as the next digit of the answer. 
Result so far: 43872.314
Subtract 3864 from 4540 to get 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Moving on to step 12:
966 goes into 6760 6 times with a remainder of 964.
The number 6 becomes the next digit in our result. 
Result so far: 43872.3146
Subtracting 5796 from 6760 leaves us with 964.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9640, and continue the process.

Let's proceed to step 13:
If we divide 9640 by 966, we get 9 and a remainder of 946.
Use 9 as the next digit of our solution. 
Result so far: 43872.31469
Deduct 8694 from 9640 and we're left with 946.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9460, and continue the process.

Step 14:
If we divide 9460 by 966, we get 9 and a remainder of 766.
Use 9 as the next digit of our solution. 
Result so far: 43872.314699
Deduct 8694 from 9460 and we're left with 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

In conclusion, the division gives 43872.314699 with a balance of 7.66e-05.
