We divide 77173123 by 128
We want to divide 77173123 by 128.

Step 1:
7 divided by 128 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 128

Let's proceed to step 2:
77 divided by 128 is 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Append the next digit (1) from the dividend to 77 and continue with: 771 / 128

Going ahead to step 3:
The number 128 fits into 771 6 times, leaving a remainder of 3.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 3 after subtracting 768 from 771.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 128

Advancing to step 4:
If we divide 37 by 128, we get 0 and a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 60.0
Subtracting 0 from 37 leaves us with 37.
Take the next digit (3) from the dividend and append it to 37, then repeat: 373 / 128

Moving on to step 5:
128 can be fit into 373 2 times, resulting in a remainder of 117.
The next digit of our result is 2. 
Result so far: 602.0
If we subtract 256 from 373, we get 117.
Include the next digit (1) from the dividend after 117, then repeat: 1171 / 128

Advancing to step 6:
When dividing 1171 by 128, we get 9 with a remainder of 19.
The next digit of our result is 9. 
Result so far: 6029.0
Subtract 1152 from 1171 to get 19.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 128

Advancing to step 7:
The number 128 fits into 192 1 times, leaving a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 60291.0
Subtracting 128 from 192 leaves us with 64.
Include the next digit (3) from the dividend after 64, then repeat: 643 / 128

Advancing to step 8:
128 can be fit into 643 5 times, resulting in a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 602915.0
Subtract 640 from 643 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
The number 128 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 602915.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
If we divide 300 by 128, we get 2 and a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 602915.02
If we take 256 away from 300, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 11:
128 goes into 440 3 times with a remainder of 56.
Write down 3 as next digit of the result. 
Result so far: 602915.023
Subtract 384 from 440 to 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.

Step 12:
128 goes into 560 4 times with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 602915.0234
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.

Going ahead to step 13:
The number 128 fits into 480 3 times, leaving a remainder of 96.
Use 3 as the next digit of our solution. 
Result so far: 602915.02343
Deduct 384 from 480 and we're left 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.

Let's proceed to step 14:
When dividing 960 by 128, we get 7 with a remainder of 64.
The next digit of our result is 7. 
Result so far: 602915.023437
Subtract 896 from 960 to 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 15:
When dividing 640 by 128, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 602915.0234375
The remainder is 0 after subtracting 640 from 640.
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 16:
0 divided by 128 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 602915.0234375
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.

Our division results in 602915.0234375 with a remaining 0.0.
