We're dividing 29310485 by 640 
Let's see how many times 640 fits into 29310485.

Let's proceed to step 1:
640 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 640

Going ahead to step 2:
640 can be fit into 29 0 times, resulting in a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Include the next digit (3) from the dividend after 29, then repeat: 293 / 640

On to step 3:
If we divide 293 by 640, we get 0 and a remainder of 293.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 293 leaves us with 293.
Append the next digit (1) from the dividend to 293 and continue with: 2931 / 640

Moving on to step 4:
640 can be fit into 2931 4 times, resulting in a remainder of 371.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 371 after subtracting 2560 from 2931.
Take the next digit (0) from the dividend and append it to 371, then repeat: 3710 / 640

On to step 5:
When dividing 3710 by 640, we get 5 with a remainder of 510.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtracting 3200 from 3710 leaves us with 510.
Include the next digit (4) from the dividend after 510, then repeat: 5104 / 640

Moving on to step 6:
If we divide 5104 by 640, we get 7 and a remainder of 624.
The number 7 becomes the next digit in our result. 
Result so far: 457.0
If we subtract 4480 from 5104, we get 624.
Grab the next digit (8) from the dividend, add it to 624, then carry on: 6248 / 640

Step 7:
When dividing 6248 by 640, we get 9 with a remainder of 488.
Record the quotient 9 as the next digit in the result. 
Result so far: 4579.0
Subtract 5760 from 6248 to get 488.
Bring next digit (5) of the dividend behind the 488 and repeat the process: 4885 / 640

Step 8:
640 can be fit into 4885 7 times, resulting in a remainder of 405.
Put 7 as the next digit of the answer. 
Result so far: 45797.0
Subtract 4480 from 4885 to get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 9:
640 goes into 4050 6 times with a remainder of 210.
Write down 6 as next digit of the result. 
Result so far: 45797.6
Deduct 3840 from 4050 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 10:
When dividing 2100 by 640, we get 3 with a remainder of 180.
Record the quotient 3 as the next digit in the result. 
Result so far: 45797.63
If we subtract 1920 from 2100, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 11:
640 goes into 1800 2 times with a remainder of 520.
Put 2 as the next digit of the answer. 
Result so far: 45797.632
Subtracting 1280 from 1800 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 12:
If we divide 5200 by 640, we get 8 and a remainder of 80.
The next digit of our result is 8. 
Result so far: 45797.6328
If we subtract 5120 from 5200, we 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.

Moving on to step 13:
800 divided by 640 is 1 with a remainder of 160.
Write down 1 as next digit of the result. 
Result so far: 45797.63281
Subtract 640 from 800 to 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.

Step 14:
640 goes into 1600 2 times with a remainder of 320.
Put 2 as the next digit of the answer. 
Result so far: 45797.632812
Deduct 1280 from 1600 and we're left 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.

Moving on to step 15:
If we divide 3200 by 640, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 45797.6328125
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.

Moving on to step 16:
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: 45797.6328125
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.

Our division results in 45797.6328125 with a remaining 0.0.
