Let's divide 3981484 by 128
We want to divide 3981484 by 128.

Let's proceed to step 1:
128 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 128

Let's proceed to step 2:
When dividing 39 by 128, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (8) from the dividend, attach it to 39 and continue: 398 / 128

Advancing to step 3:
If we divide 398 by 128, we get 3 and a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 384 away from 398, we end up with 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 128

Let's proceed to step 4:
If we divide 141 by 128, we get 1 and a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtracting 128 from 141 leaves us with 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 128

Let's proceed to step 5:
If we divide 134 by 128, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 311.0
If we subtract 128 from 134, we get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 128

Going ahead to step 6:
When dividing 68 by 128, we get 0 with a remainder of 68.
The next digit of our result is 0. 
Result so far: 3110.0
Subtract 0 from 68 to get 68.
Append the next digit (4) from the dividend to 68 and continue with: 684 / 128

Moving on to step 7:
When dividing 684 by 128, we get 5 with a remainder of 44.
Put 5 as the next digit of the answer. 
Result so far: 31105.0
Subtract 640 from 684 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 8:
128 can be fit into 440 3 times, resulting in a remainder of 56.
The next digit of our result is 3. 
Result so far: 31105.3
If we subtract 384 from 440, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 9:
128 can be fit into 560 4 times, resulting in a remainder of 48.
The next digit of our result is 4. 
Result so far: 31105.34
Deduct 512 from 560 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
When dividing 480 by 128, we get 3 with a remainder of 96.
The next digit of our result is 3. 
Result so far: 31105.343
Subtract 384 from 480 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 11:
The number 128 fits into 960 7 times, leaving a remainder of 64.
The number 7 becomes the next digit in our result. 
Result so far: 31105.3437
If we subtract 896 from 960, 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.

Moving on to step 12:
128 goes into 640 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 31105.34375
If we take 640 away from 640, 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.

Let's proceed to step 13:
0 divided by 128 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 31105.34375
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.

Let's proceed to step 14:
If we divide 0 by 128, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 31105.34375
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.

After the division, we end up with 31105.34375 and a remainder of 0.0.
