26834978 divided by 640 
We want to figure out the number of times 26834978 can be divided by 640.

Advancing to step 1:
640 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 640

Advancing to step 2:
If we divide 26 by 640, we get 0 and a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 26 to get 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 640

Step 3:
When dividing 268 by 640, we get 0 with a remainder of 268.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 268, we end up with 268.
Fetch the next digit (3) from the dividend, attach it to 268 and continue: 2683 / 640

Moving on to step 4:
If we divide 2683 by 640, we get 4 and a remainder of 123.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 2560 from 2683, we get 123.
Take the next digit (4) from the dividend and append it to 123, then repeat: 1234 / 640

Moving on to step 5:
The number 640 fits into 1234 1 times, leaving a remainder of 594.
Put 1 as the next digit of the answer. 
Result so far: 41.0
Subtracting 640 from 1234 leaves us with 594.
Include the next digit (9) from the dividend after 594, then repeat: 5949 / 640

Step 6:
640 goes into 5949 9 times with a remainder of 189.
Put 9 as the next digit of the answer. 
Result so far: 419.0
The remainder is 189 after subtracting 5760 from 5949.
Include the next digit (7) from the dividend after 189, then repeat: 1897 / 640

Moving on to step 7:
640 goes into 1897 2 times with a remainder of 617.
The number 2 becomes the next digit in our result. 
Result so far: 4192.0
If we subtract 1280 from 1897, we get 617.
Include the next digit (8) from the dividend after 617, then repeat: 6178 / 640

On to step 8:
The number 640 fits into 6178 9 times, leaving a remainder of 418.
Put 9 as the next digit of the answer. 
Result so far: 41929.0
Subtract 5760 from 6178 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Advancing to step 9:
640 can be fit into 4180 6 times, resulting in a remainder of 340.
Write down 6 as next digit of the result. 
Result so far: 41929.6
Subtract 3840 from 4180 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 10:
3400 divided by 640 is 5 with a remainder of 200.
The next digit of our result is 5. 
Result so far: 41929.65
Deduct 3200 from 3400 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 11:
640 can be fit into 2000 3 times, resulting in a remainder of 80.
Record the quotient 3 as the next digit in the result. 
Result so far: 41929.653
Subtract 1920 from 2000 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
If we divide 800 by 640, we get 1 and a remainder of 160.
Record the quotient 1 as the next digit in the result. 
Result so far: 41929.6531
If we subtract 640 from 800, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 13:
1600 divided by 640 is 2 with a remainder of 320.
Put 2 as the next digit of the answer. 
Result so far: 41929.65312
Subtracting 1280 from 1600 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 14:
When dividing 3200 by 640, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 41929.653125
Subtract 3200 from 3200 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.

On to step 15:
If we divide 0 by 640, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 41929.653125
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.

Let's proceed to step 16:
If we divide 0 by 640, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 41929.653125
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 41929.653125 with a balance of 0.0.
