42513951 divided by 128 
Our goal is to divide 42513951 by 128.

Step 1:
128 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 128

On to step 2:
When dividing 42 by 128, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
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 / 128

Let's proceed to step 3:
425 divided by 128 is 3 with a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 384 from 425 and we're left with 41.
Append the next digit (1) from the dividend to 41 and continue with: 411 / 128

Advancing to step 4:
The number 128 fits into 411 3 times, leaving a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 33.0
The remainder is 27 after subtracting 384 from 411.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 128

Advancing to step 5:
When dividing 273 by 128, we get 2 with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 332.0
Subtracting 256 from 273 leaves us with 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 128

Advancing to step 6:
128 goes into 179 1 times with a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 3321.0
The remainder is 51 after subtracting 128 from 179.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 128

Going ahead to step 7:
128 can be fit into 515 4 times, resulting in a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 33214.0
Subtract 512 from 515 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 128

Step 8:
31 divided by 128 is 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 332140.0
If we subtract 0 from 31, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 9:
When dividing 310 by 128, we get 2 with a remainder of 54.
The next digit of our result is 2. 
Result so far: 332140.2
Subtract 256 from 310 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
When dividing 540 by 128, we get 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 332140.24
If we take 512 away from 540, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
If we divide 280 by 128, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 332140.242
The remainder is 24 after subtracting 256 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
128 can be fit into 240 1 times, resulting in a remainder of 112.
Record the quotient 1 as the next digit in the result. 
Result so far: 332140.2421
Deduct 128 from 240 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 13:
When dividing 1120 by 128, we get 8 with a remainder of 96.
Record the quotient 8 as the next digit in the result. 
Result so far: 332140.24218
The remainder is 96 after subtracting 1024 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 14:
If we divide 960 by 128, we get 7 and a remainder of 64.
The next digit of our result is 7. 
Result so far: 332140.242187
Deduct 896 from 960 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 15:
When dividing 640 by 128, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 332140.2421875
The remainder is 0 after subtracting 640 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 16:
When dividing 0 by 128, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 332140.2421875
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 332140.2421875 with a remaining 0.0.
