Moving on to step 2:
The number 128 fits into 39 0 times, leaving a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 128

Advancing to step 3:
399 divided by 128 is 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 384 from 399 to get 15.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 128

Going ahead to step 4:
128 can be fit into 157 1 times, resulting in a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtract 128 from 157 to get 29.
Bring next digit (0) of the dividend behind the 29 and repeat the process: 290 / 128

Advancing to step 5:
If we divide 290 by 128, we get 2 and a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 312.0
If we take 256 away from 290, we end up with 34.
Bring next digit (3) of the dividend behind the 34 and repeat the process: 343 / 128

Going ahead to step 6:
When dividing 343 by 128, we get 2 with a remainder of 87.
Use 2 as the next digit of our solution. 
Result so far: 3122.0
The remainder is 87 after subtracting 256 from 343.
Grab the next digit (4) from the dividend, add it to 87, then carry on: 874 / 128

Step 7:
128 can be fit into 874 6 times, resulting in a remainder of 106.
Put 6 as the next digit of the answer. 
Result so far: 31226.0
Subtract 768 from 874 to get 106.
Take the next digit (2) from the dividend and append it to 106, then repeat: 1062 / 128

Let's proceed to step 8:
128 goes into 1062 8 times with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 312268.0
The remainder is 38 after subtracting 1024 from 1062.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
The number 128 fits into 380 2 times, leaving a remainder of 124.
The next digit of our result is 2. 
Result so far: 312268.2
Deduct 256 from 380 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 10:
128 can be fit into 1240 9 times, resulting in a remainder of 88.
The next digit of our result is 9. 
Result so far: 312268.29
The remainder is 88 after subtracting 1152 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 11:
128 can be fit into 880 6 times, resulting in a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 312268.296
If we subtract 768 from 880, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 12:
1120 divided by 128 is 8 with a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 312268.2968
Subtracting 1024 from 1120 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.

Step 13:
The number 128 fits into 960 7 times, leaving a remainder of 64.
Record the quotient 7 as the next digit in the result. 
Result so far: 312268.29687
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.

Going ahead to step 14:
128 can be fit into 640 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 312268.296875
Deduct 640 from 640 and we're left 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.

On to step 15:
128 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 312268.296875
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.

Step 16:
128 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 312268.296875
If we subtract 0 from 0, we 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 quotient of the division is 312268.296875, and the remainder is 0.0.
