We're dividing 42357560 by 328 
We want to divide 42357560 by 328.

Step 1:
4 divided by 328 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 328

Moving on to step 2:
When dividing 42 by 328, we get 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 328

Advancing to step 3:
If we divide 423 by 328, we get 1 and a remainder of 95.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 328 away from 423, we end up with 95.
Append the next digit (5) from the dividend to 95 and continue with: 955 / 328

Going ahead to step 4:
The number 328 fits into 955 2 times, leaving a remainder of 299.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 656 away from 955, we end up with 299.
Take the next digit (7) from the dividend and append it to 299, then repeat: 2997 / 328

On to step 5:
If we divide 2997 by 328, we get 9 and a remainder of 45.
Put 9 as the next digit of the answer. 
Result so far: 129.0
Deduct 2952 from 2997 and we're left with 45.
Bring next digit (5) of the dividend behind the 45 and repeat the process: 455 / 328

Advancing to step 6:
When dividing 455 by 328, we get 1 with a remainder of 127.
Write down 1 as next digit of the result. 
Result so far: 1291.0
If we take 328 away from 455, we end up with 127.
Include the next digit (6) from the dividend after 127, then repeat: 1276 / 328

Advancing to step 7:
When dividing 1276 by 328, we get 3 with a remainder of 292.
The next digit of our result is 3. 
Result so far: 12913.0
The remainder is 292 after subtracting 984 from 1276.
Append the next digit (0) from the dividend to 292 and continue with: 2920 / 328

Let's proceed to step 8:
2920 divided by 328 is 8 with a remainder of 296.
The next digit of our result is 8. 
Result so far: 129138.0
Subtract 2624 from 2920 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 9:
2960 divided by 328 is 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 129138.9
If we subtract 2952 from 2960, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
When dividing 80 by 328, we get 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 129138.9
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
When dividing 800 by 328, we get 2 with a remainder of 144.
The number 2 becomes the next digit in our result. 
Result so far: 129138.902
If we take 656 away from 800, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 12:
1440 divided by 328 is 4 with a remainder of 128.
Use 4 as the next digit of our solution. 
Result so far: 129138.9024
If we subtract 1312 from 1440, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 13:
If we divide 1280 by 328, we get 3 and a remainder of 296.
The number 3 becomes the next digit in our result. 
Result so far: 129138.90243
If we take 984 away from 1280, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 14:
328 can be fit into 2960 9 times, resulting in a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 129138.902439
Deduct 2952 from 2960 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 15:
The number 328 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 129138.902439
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 16:
If we divide 800 by 328, we get 2 and a remainder of 144.
The number 2 becomes the next digit in our result. 
Result so far: 129138.90243902
If we take 656 away from 800, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The final outcome is 129138.90243902, with a leftover of 1.44e-07.
