We're dividing 78302308 by 128 
We want to divide 78302308 by 128.

Step 1:
128 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 128

On to step 2:
128 can be fit into 78 0 times, resulting in a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Append the next digit (3) from the dividend to 78 and continue with: 783 / 128

Going ahead to step 3:
783 divided by 128 is 6 with a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 768 from 783 leaves us with 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 128

Let's proceed to step 4:
128 goes into 150 1 times with a remainder of 22.
The next digit of our result is 1. 
Result so far: 61.0
If we take 128 away from 150, we end up with 22.
Take the next digit (2) from the dividend and append it to 22, then repeat: 222 / 128

Advancing to step 5:
222 divided by 128 is 1 with a remainder of 94.
Put 1 as the next digit of the answer. 
Result so far: 611.0
If we subtract 128 from 222, we get 94.
Fetch the next digit (3) from the dividend, attach it to 94 and continue: 943 / 128

Let's proceed to step 6:
943 divided by 128 is 7 with a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 6117.0
If we subtract 896 from 943, we get 47.
Append the next digit (0) from the dividend to 47 and continue with: 470 / 128

Going ahead to step 7:
128 can be fit into 470 3 times, resulting in a remainder of 86.
Put 3 as the next digit of the answer. 
Result so far: 61173.0
If we subtract 384 from 470, we get 86.
Append the next digit (8) from the dividend to 86 and continue with: 868 / 128

Advancing to step 8:
The number 128 fits into 868 6 times, leaving a remainder of 100.
Use 6 as the next digit of our solution. 
Result so far: 611736.0
Subtract 768 from 868 to get 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 9:
When dividing 1000 by 128, we get 7 with a remainder of 104.
Write down 7 as next digit of the result. 
Result so far: 611736.7
Deduct 896 from 1000 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 10:
128 can be fit into 1040 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 611736.78
Subtract 1024 from 1040 to get 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 11:
The number 128 fits into 160 1 times, leaving a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 611736.781
If we subtract 128 from 160, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
If we divide 320 by 128, we get 2 and a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 611736.7812
If we subtract 256 from 320, 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.

Going ahead to step 13:
640 divided by 128 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 611736.78125
Subtracting 640 from 640 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.

Step 14:
128 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 611736.78125
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.

Step 15:
0 divided by 128 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 611736.78125
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.

The final result is 611736.78125 with a remainder of 0.0.
