Let's divide 38663904 by 128
We want to divide 38663904 by 128.

Advancing to step 1:
When dividing 3 by 128, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 128

Step 2:
The number 128 fits into 38 0 times, leaving a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Fetch the next digit (6) from the dividend, attach it to 38 and continue: 386 / 128

Advancing to step 3:
128 can be fit into 386 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 2 after subtracting 384 from 386.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 128

Let's proceed to step 4:
128 goes into 26 0 times with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Deduct 0 from 26 and we're left with 26.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 128

Moving on to step 5:
128 can be fit into 263 2 times, resulting in a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 302.0
The remainder is 7 after subtracting 256 from 263.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 128

Moving on to step 6:
79 divided by 128 is 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 3020.0
The remainder is 79 after subtracting 0 from 79.
Append the next digit (0) from the dividend to 79 and continue with: 790 / 128

On to step 7:
When dividing 790 by 128, we get 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 30206.0
Subtract 768 from 790 to get 22.
Append the next digit (4) from the dividend to 22 and continue with: 224 / 128

Step 8:
224 divided by 128 is 1 with a remainder of 96.
Use 1 as the next digit of our solution. 
Result so far: 302061.0
Subtracting 128 from 224 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 9:
If we divide 960 by 128, we get 7 and a remainder of 64.
Put 7 as the next digit of the answer. 
Result so far: 302061.7
The remainder is 64 after subtracting 896 from 960.
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 10:
128 goes into 640 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 302061.75
Subtract 640 from 640 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
When dividing 0 by 128, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 302061.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
If we divide 0 by 128, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 302061.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 302061.75, with a leftover of 0.0.
