We're dividing 77957089 by 128 
We want to divide 77957089 by 128.

Moving on to step 1:
128 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 128

Step 2:
77 divided by 128 is 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Append the next digit (9) from the dividend to 77 and continue with: 779 / 128

Advancing to step 3:
When dividing 779 by 128, we get 6 with a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 768 from 779, we get 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 128

Going ahead to step 4:
If we divide 115 by 128, we get 0 and a remainder of 115.
The next digit of our result is 0. 
Result so far: 60.0
If we take 0 away from 115, we end up with 115.
Include the next digit (7) from the dividend after 115, then repeat: 1157 / 128

Advancing to step 5:
128 can be fit into 1157 9 times, resulting in a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 609.0
If we subtract 1152 from 1157, we get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 128

Advancing to step 6:
128 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 6090.0
Subtracting 0 from 50 leaves us with 50.
Take the next digit (8) from the dividend and append it to 50, then repeat: 508 / 128

Let's proceed to step 7:
When dividing 508 by 128, we get 3 with a remainder of 124.
Write down 3 as next digit of the result. 
Result so far: 60903.0
Subtract 384 from 508 to get 124.
Bring next digit (9) of the dividend behind the 124 and repeat the process: 1249 / 128

Going ahead to step 8:
If we divide 1249 by 128, we get 9 and a remainder of 97.
The next digit of our result is 9. 
Result so far: 609039.0
If we subtract 1152 from 1249, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 9:
The number 128 fits into 970 7 times, leaving a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 609039.7
The remainder is 74 after subtracting 896 from 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 10:
128 can be fit into 740 5 times, resulting in a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 609039.75
If we take 640 away from 740, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
If we divide 1000 by 128, we get 7 and a remainder of 104.
Use 7 as the next digit of our solution. 
Result so far: 609039.757
If we subtract 896 from 1000, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 12:
128 can be fit into 1040 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 609039.7578
If we take 1024 away from 1040, we end up 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.

Advancing to step 13:
If we divide 160 by 128, we get 1 and a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 609039.75781
If we take 128 away from 160, we end up 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.

Moving on to step 14:
128 can be fit into 320 2 times, resulting in a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 609039.757812
Subtracting 256 from 320 leaves us 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.

Advancing to step 15:
128 can be fit into 640 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 609039.7578125
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.

Moving on to step 16:
The number 128 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 609039.7578125
The remainder is 0 after subtracting 0 from 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 609039.7578125 and a remainder of 0.0.
