We look at the division of 98871907 by 128 
Let's see how many times 128 fits into 98871907.

Step 1:
128 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 128

Step 2:
128 goes into 98 0 times with a remainder of 98.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Fetch the next digit (8) from the dividend, attach it to 98 and continue: 988 / 128

Going ahead to step 3:
The number 128 fits into 988 7 times, leaving a remainder of 92.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 896 from 988 to get 92.
Grab the next digit (7) from the dividend, add it to 92, then carry on: 927 / 128

Advancing to step 4:
When dividing 927 by 128, we get 7 with a remainder of 31.
The next digit of our result is 7. 
Result so far: 77.0
If we take 896 away from 927, we end up with 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 128

Let's proceed to step 5:
When dividing 311 by 128, we get 2 with a remainder of 55.
Use 2 as the next digit of our solution. 
Result so far: 772.0
Subtracting 256 from 311 leaves us with 55.
Take the next digit (9) from the dividend and append it to 55, then repeat: 559 / 128

Going ahead to step 6:
When dividing 559 by 128, we get 4 with a remainder of 47.
The number 4 becomes the next digit in our result. 
Result so far: 7724.0
Subtract 512 from 559 to get 47.
Take the next digit (0) from the dividend and append it to 47, then repeat: 470 / 128

Moving on to step 7:
The number 128 fits into 470 3 times, leaving a remainder of 86.
Write down 3 as next digit of the result. 
Result so far: 77243.0
Subtracting 384 from 470 leaves us with 86.
Take the next digit (7) from the dividend and append it to 86, then repeat: 867 / 128

Going ahead to step 8:
If we divide 867 by 128, we get 6 and a remainder of 99.
Put 6 as the next digit of the answer. 
Result so far: 772436.0
Subtract 768 from 867 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 9:
128 can be fit into 990 7 times, resulting in a remainder of 94.
Use 7 as the next digit of our solution. 
Result so far: 772436.7
Deduct 896 from 990 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 10:
940 divided by 128 is 7 with a remainder of 44.
The next digit of our result is 7. 
Result so far: 772436.77
Subtract 896 from 940 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.

The quotient of the division is 772436.77, and the remainder is 0.044.
