We're dividing 30302712 by 640 
Our goal is to divide 30302712 by 640.

Step 1:
640 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 640

On to step 2:
If we divide 30 by 640, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 640

Moving on to step 3:
When dividing 303 by 640, we get 0 with a remainder of 303.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 303 and we're left with 303.
Take the next digit (0) from the dividend and append it to 303, then repeat: 3030 / 640

On to step 4:
640 goes into 3030 4 times with a remainder of 470.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 2560 from 3030 leaves us with 470.
Grab the next digit (2) from the dividend, add it to 470, then carry on: 4702 / 640

On to step 5:
If we divide 4702 by 640, we get 7 and a remainder of 222.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
The remainder is 222 after subtracting 4480 from 4702.
Append the next digit (7) from the dividend to 222 and continue with: 2227 / 640

Moving on to step 6:
When dividing 2227 by 640, we get 3 with a remainder of 307.
Put 3 as the next digit of the answer. 
Result so far: 473.0
Subtracting 1920 from 2227 leaves us with 307.
Take the next digit (1) from the dividend and append it to 307, then repeat: 3071 / 640

Step 7:
The number 640 fits into 3071 4 times, leaving a remainder of 511.
The next digit of our result is 4. 
Result so far: 4734.0
If we subtract 2560 from 3071, we get 511.
Bring next digit (2) of the dividend behind the 511 and repeat the process: 5112 / 640

On to step 8:
If we divide 5112 by 640, we get 7 and a remainder of 632.
Put 7 as the next digit of the answer. 
Result so far: 47347.0
Subtract 4480 from 5112 to get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

On to step 9:
6320 divided by 640 is 9 with a remainder of 560.
Write down 9 as next digit of the result. 
Result so far: 47347.9
Subtract 5760 from 6320 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 10:
The number 640 fits into 5600 8 times, leaving a remainder of 480.
Use 8 as the next digit of our solution. 
Result so far: 47347.98
Subtracting 5120 from 5600 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.

Let's proceed to step 11:
The number 640 fits into 4800 7 times, leaving a remainder of 320.
The next digit of our result is 7. 
Result so far: 47347.987
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 12:
If we divide 3200 by 640, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 47347.9875
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.

Let's proceed to step 13:
0 divided by 640 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 47347.9875
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.

Let's proceed to step 14:
0 divided by 640 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 47347.9875
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.

The quotient of the division is 47347.9875, and the remainder is 0.0.
