78813770 divided by 128 
We want to figure out the number of times 78813770 can be divided 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.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 128

Advancing to step 2:
The number 128 fits into 78 0 times, leaving a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Take the next digit (8) from the dividend and append it to 78, then repeat: 788 / 128

Moving on to step 3:
The number 128 fits into 788 6 times, leaving a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 768 from 788, we get 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 128

On to step 4:
When dividing 201 by 128, we get 1 with a remainder of 73.
The next digit of our result is 1. 
Result so far: 61.0
Deduct 128 from 201 and we're left with 73.
Include the next digit (3) from the dividend after 73, then repeat: 733 / 128

Step 5:
733 divided by 128 is 5 with a remainder of 93.
Use 5 as the next digit of our solution. 
Result so far: 615.0
Subtracting 640 from 733 leaves us with 93.
Include the next digit (7) from the dividend after 93, then repeat: 937 / 128

Moving on to step 6:
937 divided by 128 is 7 with a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 6157.0
Subtract 896 from 937 to get 41.
Grab the next digit (7) from the dividend, add it to 41, then carry on: 417 / 128

Going ahead to step 7:
If we divide 417 by 128, we get 3 and a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 61573.0
Deduct 384 from 417 and we're left with 33.
Take the next digit (0) from the dividend and append it to 33, then repeat: 330 / 128

Let's proceed to step 8:
128 goes into 330 2 times with a remainder of 74.
The next digit of our result is 2. 
Result so far: 615732.0
The remainder is 74 after subtracting 256 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 9:
The number 128 fits into 740 5 times, leaving a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 615732.5
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.

Step 10:
128 goes into 1000 7 times with a remainder of 104.
Put 7 as the next digit of the answer. 
Result so far: 615732.57
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.

Step 11:
The number 128 fits into 1040 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 615732.578
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 12:
160 divided by 128 is 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 615732.5781
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.

Advancing to step 13:
320 divided by 128 is 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 615732.57812
The remainder is 64 after subtracting 256 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 14:
128 can be fit into 640 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 615732.578125
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.

Step 15:
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: 615732.578125
Subtract 0 from 0 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.

Advancing to step 16:
When dividing 0 by 128, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 615732.578125
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.

In conclusion, the division gives 615732.578125 with a balance of 0.0.
