We look at the division of 30285247 by 640 
Let's see how many times 640 fits into 30285247.

Step 1:
If we divide 3 by 640, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 640

Going ahead to step 2:
640 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 640

Going ahead to step 3:
If we divide 302 by 640, we get 0 and a remainder of 302.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 302, we get 302.
Grab the next digit (8) from the dividend, add it to 302, then carry on: 3028 / 640

Step 4:
640 goes into 3028 4 times with a remainder of 468.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 2560 from 3028 to get 468.
Fetch the next digit (5) from the dividend, attach it to 468 and continue: 4685 / 640

Moving on to step 5:
When dividing 4685 by 640, we get 7 with a remainder of 205.
Put 7 as the next digit of the answer. 
Result so far: 47.0
If we take 4480 away from 4685, we end up with 205.
Grab the next digit (2) from the dividend, add it to 205, then carry on: 2052 / 640

On to step 6:
When dividing 2052 by 640, we get 3 with a remainder of 132.
Put 3 as the next digit of the answer. 
Result so far: 473.0
If we subtract 1920 from 2052, we get 132.
Take the next digit (4) from the dividend and append it to 132, then repeat: 1324 / 640

Let's proceed to step 7:
When dividing 1324 by 640, we get 2 with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 4732.0
Subtract 1280 from 1324 to get 44.
Fetch the next digit (7) from the dividend, attach it to 44 and continue: 447 / 640

Going ahead to step 8:
447 divided by 640 is 0 with a remainder of 447.
The next digit of our result is 0. 
Result so far: 47320.0
If we take 0 away from 447, we end up with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Going ahead to step 9:
640 can be fit into 4470 6 times, resulting in a remainder of 630.
The next digit of our result is 6. 
Result so far: 47320.6
If we take 3840 away from 4470, we end up with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Step 10:
The number 640 fits into 6300 9 times, leaving a remainder of 540.
Record the quotient 9 as the next digit in the result. 
Result so far: 47320.69
The remainder is 540 after subtracting 5760 from 6300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 11:
If we divide 5400 by 640, we get 8 and a remainder of 280.
The number 8 becomes the next digit in our result. 
Result so far: 47320.698
If we subtract 5120 from 5400, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 12:
640 goes into 2800 4 times with a remainder of 240.
Write down 4 as next digit of the result. 
Result so far: 47320.6984
Subtract 2560 from 2800 to 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.

Moving on to step 13:
640 can be fit into 2400 3 times, resulting in a remainder of 480.
Use 3 as the next digit of our solution. 
Result so far: 47320.69843
Subtracting 1920 from 2400 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 14:
640 goes into 4800 7 times with a remainder of 320.
The number 7 becomes the next digit in our result. 
Result so far: 47320.698437
The remainder is 320 after subtracting 4480 from 4800.
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 15:
When dividing 3200 by 640, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 47320.6984375
The remainder is 0 after subtracting 3200 from 3200.
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 16:
640 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 47320.6984375
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 47320.6984375 with a balance of 0.0.
