9063863 ÷ 640 
We're looking to find how many times 640 goes into 9063863.

Step 1:
640 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 640

Advancing to step 2:
The number 640 fits into 90 0 times, leaving a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Bring next digit (6) of the dividend behind the 90 and repeat the process: 906 / 640

Step 3:
640 goes into 906 1 times with a remainder of 266.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 640 from 906 leaves us with 266.
Include the next digit (3) from the dividend after 266, then repeat: 2663 / 640

Step 4:
640 can be fit into 2663 4 times, resulting in a remainder of 103.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 2560 from 2663 and we're left with 103.
Include the next digit (8) from the dividend after 103, then repeat: 1038 / 640

On to step 5:
When dividing 1038 by 640, we get 1 with a remainder of 398.
The next digit of our result is 1. 
Result so far: 141.0
If we subtract 640 from 1038, we get 398.
Fetch the next digit (6) from the dividend, attach it to 398 and continue: 3986 / 640

Going ahead to step 6:
3986 divided by 640 is 6 with a remainder of 146.
Write down 6 as next digit of the result. 
Result so far: 1416.0
Deduct 3840 from 3986 and we're left with 146.
Take the next digit (3) from the dividend and append it to 146, then repeat: 1463 / 640

Moving on to step 7:
If we divide 1463 by 640, we get 2 and a remainder of 183.
The number 2 becomes the next digit in our result. 
Result so far: 14162.0
The remainder is 183 after subtracting 1280 from 1463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Going ahead to step 8:
1830 divided by 640 is 2 with a remainder of 550.
The next digit of our result is 2. 
Result so far: 14162.2
Deduct 1280 from 1830 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Advancing to step 9:
When dividing 5500 by 640, we get 8 with a remainder of 380.
Write down 8 as next digit of the result. 
Result so far: 14162.28
The remainder is 380 after subtracting 5120 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 10:
640 can be fit into 3800 5 times, resulting in a remainder of 600.
Write down 5 as next digit of the result. 
Result so far: 14162.285
If we take 3200 away from 3800, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 11:
The number 640 fits into 6000 9 times, leaving a remainder of 240.
Record the quotient 9 as the next digit in the result. 
Result so far: 14162.2859
If we take 5760 away from 6000, we end up 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.

Moving on to step 12:
If we divide 2400 by 640, we get 3 and a remainder of 480.
The next digit of our result is 3. 
Result so far: 14162.28593
Subtract 1920 from 2400 to 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.

Moving on to step 13:
4800 divided by 640 is 7 with a remainder of 320.
Use 7 as the next digit of our solution. 
Result so far: 14162.285937
Deduct 4480 from 4800 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.

Advancing to step 14:
640 goes into 3200 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 14162.2859375
Deduct 3200 from 3200 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.

Let's proceed to step 15:
640 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 14162.2859375
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.

The quotient of the division is 14162.2859375, and the remainder is 0.0.
