42581574 divided by 328 
We want to divide 42581574 by 328.

Going ahead to step 1:
328 goes into 4 0 times 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.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 328

Going ahead to step 2:
The number 328 fits into 42 0 times, leaving a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 328

Step 3:
425 divided by 328 is 1 with a remainder of 97.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 97 after subtracting 328 from 425.
Take the next digit (8) from the dividend and append it to 97, then repeat: 978 / 328

Moving on to step 4:
328 can be fit into 978 2 times, resulting in a remainder of 322.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 656 from 978 to get 322.
Append the next digit (1) from the dividend to 322 and continue with: 3221 / 328

Let's proceed to step 5:
3221 divided by 328 is 9 with a remainder of 269.
The next digit of our result is 9. 
Result so far: 129.0
Subtracting 2952 from 3221 leaves us with 269.
Include the next digit (5) from the dividend after 269, then repeat: 2695 / 328

Let's proceed to step 6:
328 goes into 2695 8 times with a remainder of 71.
Put 8 as the next digit of the answer. 
Result so far: 1298.0
If we subtract 2624 from 2695, we get 71.
Grab the next digit (7) from the dividend, add it to 71, then carry on: 717 / 328

Let's proceed to step 7:
328 goes into 717 2 times with a remainder of 61.
The number 2 becomes the next digit in our result. 
Result so far: 12982.0
Subtract 656 from 717 to get 61.
Bring next digit (4) of the dividend behind the 61 and repeat the process: 614 / 328

Advancing to step 8:
328 can be fit into 614 1 times, resulting in a remainder of 286.
The next digit of our result is 1. 
Result so far: 129821.0
If we subtract 328 from 614, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Advancing to step 9:
328 can be fit into 2860 8 times, resulting in a remainder of 236.
Write down 8 as next digit of the result. 
Result so far: 129821.8
Subtracting 2624 from 2860 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 10:
When dividing 2360 by 328, we get 7 with a remainder of 64.
The number 7 becomes the next digit in our result. 
Result so far: 129821.87
If we subtract 2296 from 2360, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 11:
640 divided by 328 is 1 with a remainder of 312.
Use 1 as the next digit of our solution. 
Result so far: 129821.871
Subtract 328 from 640 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 12:
3120 divided by 328 is 9 with a remainder of 168.
Write down 9 as next digit of the result. 
Result so far: 129821.8719
The remainder is 168 after subtracting 2952 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 13:
The number 328 fits into 1680 5 times, leaving a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 129821.87195
The remainder is 40 after subtracting 1640 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
The number 328 fits into 400 1 times, leaving a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 129821.871951
The remainder is 72 after subtracting 328 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 15:
The number 328 fits into 720 2 times, leaving a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 129821.8719512
If we subtract 656 from 720, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 16:
When dividing 640 by 328, we get 1 with a remainder of 312.
Write down 1 as next digit of the result. 
Result so far: 129821.87195121
Subtract 328 from 640 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The final result is 129821.87195121 with a remainder of 3.12e-07.
