49951689 divided by 128 
Let's see how many times 128 fits into 49951689.

On to 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
If we subtract 0 from 4, we get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 128

Moving on to step 2:
If we divide 49 by 128, we get 0 and a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Bring next digit (9) of the dividend behind the 49 and repeat the process: 499 / 128

On to step 3:
128 goes into 499 3 times with a remainder of 115.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 384 from 499, we get 115.
Fetch the next digit (5) from the dividend, attach it to 115 and continue: 1155 / 128

Let's proceed to step 4:
1155 divided by 128 is 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 39.0
Subtract 1152 from 1155 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 128

Let's proceed to step 5:
When dividing 31 by 128, we get 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 390.0
Subtracting 0 from 31 leaves us with 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 128

Moving on to step 6:
128 can be fit into 316 2 times, resulting in a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 3902.0
Subtract 256 from 316 to get 60.
Bring next digit (8) of the dividend behind the 60 and repeat the process: 608 / 128

Going ahead to step 7:
When dividing 608 by 128, we get 4 with a remainder of 96.
Put 4 as the next digit of the answer. 
Result so far: 39024.0
Subtracting 512 from 608 leaves us with 96.
Include the next digit (9) from the dividend after 96, then repeat: 969 / 128

Going ahead to step 8:
128 goes into 969 7 times with a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 390247.0
If we subtract 896 from 969, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 9:
128 can be fit into 730 5 times, resulting in a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 390247.5
If we subtract 640 from 730, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
The number 128 fits into 900 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 390247.57
Subtract 896 from 900 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
128 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 390247.57
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
The number 128 fits into 400 3 times, leaving a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 390247.5703
Deduct 384 from 400 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
When dividing 160 by 128, we get 1 with a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 390247.57031
Deduct 128 from 160 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
If we divide 320 by 128, we get 2 and a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 390247.570312
Deduct 256 from 320 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 15:
640 divided by 128 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 390247.5703125
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.

On to step 16:
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: 390247.5703125
Subtracting 0 from 0 leaves us 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.

The quotient of the division is 390247.5703125, and the remainder is 0.0.
