We're dividing 26093581 by 640 
We want to figure out the number of times 26093581 can be divided by 640.

Let's proceed to step 1:
If we divide 2 by 640, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 640

Let's proceed to step 2:
If we divide 26 by 640, we get 0 and a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 26, we end up with 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 640

Moving on to step 3:
The number 640 fits into 260 0 times, leaving a remainder of 260.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 260 and we're left with 260.
Bring next digit (9) of the dividend behind the 260 and repeat the process: 2609 / 640

Let's proceed to step 4:
The number 640 fits into 2609 4 times, leaving a remainder of 49.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 2560 from 2609, we get 49.
Take the next digit (3) from the dividend and append it to 49, then repeat: 493 / 640

Let's proceed to step 5:
If we divide 493 by 640, we get 0 and a remainder of 493.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Deduct 0 from 493 and we're left with 493.
Append the next digit (5) from the dividend to 493 and continue with: 4935 / 640

On to step 6:
640 goes into 4935 7 times with a remainder of 455.
The next digit of our result is 7. 
Result so far: 407.0
If we take 4480 away from 4935, we end up with 455.
Take the next digit (8) from the dividend and append it to 455, then repeat: 4558 / 640

Moving on to step 7:
640 can be fit into 4558 7 times, resulting in a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 4077.0
If we subtract 4480 from 4558, we get 78.
Append the next digit (1) from the dividend to 78 and continue with: 781 / 640

Moving on to step 8:
781 divided by 640 is 1 with a remainder of 141.
The number 1 becomes the next digit in our result. 
Result so far: 40771.0
Subtract 640 from 781 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Step 9:
640 can be fit into 1410 2 times, resulting in a remainder of 130.
Write down 2 as next digit of the result. 
Result so far: 40771.2
Subtract 1280 from 1410 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 10:
When dividing 1300 by 640, we get 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 40771.22
If we subtract 1280 from 1300, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 40771.22 with a balance of 0.02.
