We divide 20930908 by 640
Our goal is to divide 20930908 by 640.

Let's proceed to step 1:
640 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 640

Going ahead to step 2:
When dividing 20 by 640, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 640

Going ahead to step 3:
The number 640 fits into 209 0 times, leaving a remainder of 209.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 209 and we're left with 209.
Take the next digit (3) from the dividend and append it to 209, then repeat: 2093 / 640

Moving on to step 4:
2093 divided by 640 is 3 with a remainder of 173.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 173 after subtracting 1920 from 2093.
Bring next digit (0) of the dividend behind the 173 and repeat the process: 1730 / 640

Going ahead to step 5:
The number 640 fits into 1730 2 times, leaving a remainder of 450.
Write down 2 as next digit of the result. 
Result so far: 32.0
Subtracting 1280 from 1730 leaves us with 450.
Append the next digit (9) from the dividend to 450 and continue with: 4509 / 640

Step 6:
4509 divided by 640 is 7 with a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 327.0
If we subtract 4480 from 4509, we get 29.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 640

Moving on to step 7:
290 divided by 640 is 0 with a remainder of 290.
Record the quotient 0 as the next digit in the result. 
Result so far: 3270.0
If we take 0 away from 290, we end up with 290.
Fetch the next digit (8) from the dividend, attach it to 290 and continue: 2908 / 640

Step 8:
When dividing 2908 by 640, we get 4 with a remainder of 348.
The number 4 becomes the next digit in our result. 
Result so far: 32704.0
If we subtract 2560 from 2908, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 9:
640 goes into 3480 5 times with a remainder of 280.
The next digit of our result is 5. 
Result so far: 32704.5
If we take 3200 away from 3480, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 10:
640 goes into 2800 4 times with a remainder of 240.
The next digit of our result is 4. 
Result so far: 32704.54
If we subtract 2560 from 2800, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 11:
640 can be fit into 2400 3 times, resulting in a remainder of 480.
Put 3 as the next digit of the answer. 
Result so far: 32704.543
The remainder is 480 after subtracting 1920 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 12:
When dividing 4800 by 640, we get 7 with a remainder of 320.
Put 7 as the next digit of the answer. 
Result so far: 32704.5437
Subtract 4480 from 4800 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 13:
640 can be fit into 3200 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 32704.54375
If we subtract 3200 from 3200, we 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.

Moving on to step 14:
640 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 32704.54375
Subtracting 0 from 0 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.

Going ahead to step 15:
640 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 32704.54375
If we subtract 0 from 0, we 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.

In conclusion, the division gives 32704.54375 with a balance of 0.0.
