We're dividing 31033122 by 640 
Let's see how many times 640 fits into 31033122.

Let's proceed to step 1:
The number 640 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 640

Going ahead to step 2:
31 divided by 640 is 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 640

Going ahead to step 3:
If we divide 310 by 640, we get 0 and a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 310 and we're left with 310.
Fetch the next digit (3) from the dividend, attach it to 310 and continue: 3103 / 640

Advancing to step 4:
640 goes into 3103 4 times with a remainder of 543.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 543 after subtracting 2560 from 3103.
Grab the next digit (3) from the dividend, add it to 543, then carry on: 5433 / 640

Let's proceed to step 5:
If we divide 5433 by 640, we get 8 and a remainder of 313.
Put 8 as the next digit of the answer. 
Result so far: 48.0
If we subtract 5120 from 5433, we get 313.
Grab the next digit (1) from the dividend, add it to 313, then carry on: 3131 / 640

Step 6:
If we divide 3131 by 640, we get 4 and a remainder of 571.
Use 4 as the next digit of our solution. 
Result so far: 484.0
Subtracting 2560 from 3131 leaves us with 571.
Append the next digit (2) from the dividend to 571 and continue with: 5712 / 640

Moving on to step 7:
5712 divided by 640 is 8 with a remainder of 592.
Use 8 as the next digit of our solution. 
Result so far: 4848.0
If we subtract 5120 from 5712, we get 592.
Fetch the next digit (2) from the dividend, attach it to 592 and continue: 5922 / 640

Step 8:
When dividing 5922 by 640, we get 9 with a remainder of 162.
Record the quotient 9 as the next digit in the result. 
Result so far: 48489.0
If we subtract 5760 from 5922, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 9:
When dividing 1620 by 640, we get 2 with a remainder of 340.
Write down 2 as next digit of the result. 
Result so far: 48489.2
Subtracting 1280 from 1620 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 10:
3400 divided by 640 is 5 with a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 48489.25
If we subtract 3200 from 3400, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 11:
2000 divided by 640 is 3 with a remainder of 80.
The next digit of our result is 3. 
Result so far: 48489.253
The remainder is 80 after subtracting 1920 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
The number 640 fits into 800 1 times, leaving a remainder of 160.
The number 1 becomes the next digit in our result. 
Result so far: 48489.2531
Deduct 640 from 800 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 13:
If we divide 1600 by 640, we get 2 and a remainder of 320.
Write down 2 as next digit of the result. 
Result so far: 48489.25312
Subtracting 1280 from 1600 leaves us 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.

On to step 14:
640 can be fit into 3200 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 48489.253125
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.

Going ahead to step 15:
If we divide 0 by 640, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 48489.253125
If we take 0 away from 0, 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.

Step 16:
The number 640 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 48489.253125
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.

The final result is 48489.253125 with a remainder of 0.0.
