We look at the division of 40829169 by 128 
Let's see how many times 128 fits into 40829169.

Going ahead to step 1:
128 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 128

On to step 2:
128 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 128

On to step 3:
The number 128 fits into 408 3 times, leaving a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 24 after subtracting 384 from 408.
Grab the next digit (2) from the dividend, add it to 24, then carry on: 242 / 128

On to step 4:
When dividing 242 by 128, we get 1 with a remainder of 114.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we subtract 128 from 242, we get 114.
Grab the next digit (9) from the dividend, add it to 114, then carry on: 1149 / 128

Advancing to step 5:
When dividing 1149 by 128, we get 8 with a remainder of 125.
The number 8 becomes the next digit in our result. 
Result so far: 318.0
If we subtract 1024 from 1149, we get 125.
Bring next digit (1) of the dividend behind the 125 and repeat the process: 1251 / 128

Moving on to step 6:
When dividing 1251 by 128, we get 9 with a remainder of 99.
Write down 9 as next digit of the result. 
Result so far: 3189.0
If we subtract 1152 from 1251, we get 99.
Fetch the next digit (6) from the dividend, attach it to 99 and continue: 996 / 128

Step 7:
The number 128 fits into 996 7 times, leaving a remainder of 100.
Record the quotient 7 as the next digit in the result. 
Result so far: 31897.0
If we take 896 away from 996, we end up with 100.
Include the next digit (9) from the dividend after 100, then repeat: 1009 / 128

Advancing to step 8:
128 goes into 1009 7 times with a remainder of 113.
Put 7 as the next digit of the answer. 
Result so far: 318977.0
Subtract 896 from 1009 to get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Let's proceed to step 9:
128 goes into 1130 8 times with a remainder of 106.
The next digit of our result is 8. 
Result so far: 318977.8
Subtracting 1024 from 1130 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 10:
128 can be fit into 1060 8 times, resulting in a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 318977.88
The remainder is 36 after subtracting 1024 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 318977.88 with a remainder of 0.036.
