Let's divide 22717308 by 640
Let's see how many times 640 fits into 22717308.

Advancing to step 1:
The number 640 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 640

Advancing to step 2:
22 divided by 640 is 0 with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Grab the next digit (7) from the dividend, add it to 22, then carry on: 227 / 640

Step 3:
640 can be fit into 227 0 times, resulting in a remainder of 227.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 227, we end up with 227.
Bring next digit (1) of the dividend behind the 227 and repeat the process: 2271 / 640

Let's proceed to step 4:
The number 640 fits into 2271 3 times, leaving a remainder of 351.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 1920 from 2271, we get 351.
Bring next digit (7) of the dividend behind the 351 and repeat the process: 3517 / 640

Going ahead to step 5:
If we divide 3517 by 640, we get 5 and a remainder of 317.
Write down 5 as next digit of the result. 
Result so far: 35.0
Subtracting 3200 from 3517 leaves us with 317.
Append the next digit (3) from the dividend to 317 and continue with: 3173 / 640

Moving on to step 6:
640 goes into 3173 4 times with a remainder of 613.
The next digit of our result is 4. 
Result so far: 354.0
The remainder is 613 after subtracting 2560 from 3173.
Take the next digit (0) from the dividend and append it to 613, then repeat: 6130 / 640

Moving on to step 7:
6130 divided by 640 is 9 with a remainder of 370.
Put 9 as the next digit of the answer. 
Result so far: 3549.0
Subtracting 5760 from 6130 leaves us with 370.
Fetch the next digit (8) from the dividend, attach it to 370 and continue: 3708 / 640

Going ahead to step 8:
If we divide 3708 by 640, we get 5 and a remainder of 508.
Use 5 as the next digit of our solution. 
Result so far: 35495.0
Deduct 3200 from 3708 and we're left with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Moving on to step 9:
640 goes into 5080 7 times with a remainder of 600.
Put 7 as the next digit of the answer. 
Result so far: 35495.7
Subtract 4480 from 5080 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 10:
640 goes into 6000 9 times with a remainder of 240.
Use 9 as the next digit of our solution. 
Result so far: 35495.79
Deduct 5760 from 6000 and we're left with 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:
2400 divided by 640 is 3 with a remainder of 480.
The number 3 becomes the next digit in our result. 
Result so far: 35495.793
If we subtract 1920 from 2400, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 12:
4800 divided by 640 is 7 with a remainder of 320.
The number 7 becomes the next digit in our result. 
Result so far: 35495.7937
If we subtract 4480 from 4800, we 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:
If we divide 3200 by 640, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 35495.79375
If we take 3200 away from 3200, 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.

Let's proceed to step 14:
The number 640 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 35495.79375
Deduct 0 from 0 and we're left 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:
When dividing 0 by 640, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 35495.79375
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.

After the division, we end up with 35495.79375 and a remainder of 0.0.
