Advancing to step 5:
640 goes into 2175 3 times with a remainder of 255.
The next digit of our result is 3. 
Result so far: 43.0
Subtract 1920 from 2175 to get 255.
Bring next digit (6) of the dividend behind the 255 and repeat the process: 2556 / 640

On to step 6:
640 goes into 2556 3 times with a remainder of 636.
Use 3 as the next digit of our solution. 
Result so far: 433.0
If we subtract 1920 from 2556, we get 636.
Include the next digit (5) from the dividend after 636, then repeat: 6365 / 640

On to step 7:
When dividing 6365 by 640, we get 9 with a remainder of 605.
Use 9 as the next digit of our solution. 
Result so far: 4339.0
If we subtract 5760 from 6365, we get 605.
Append the next digit (3) from the dividend to 605 and continue with: 6053 / 640

Advancing to step 8:
6053 divided by 640 is 9 with a remainder of 293.
The next digit of our result is 9. 
Result so far: 43399.0
Subtracting 5760 from 6053 leaves us with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Moving on to step 9:
The number 640 fits into 2930 4 times, leaving a remainder of 370.
Use 4 as the next digit of our solution. 
Result so far: 43399.4
If we subtract 2560 from 2930, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 10:
3700 divided by 640 is 5 with a remainder of 500.
Record the quotient 5 as the next digit in the result. 
Result so far: 43399.45
Subtract 3200 from 3700 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 11:
640 goes into 5000 7 times with a remainder of 520.
The number 7 becomes the next digit in our result. 
Result so far: 43399.457
The remainder is 520 after subtracting 4480 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 12:
If we divide 5200 by 640, we get 8 and a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 43399.4578
Deduct 5120 from 5200 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
640 can be fit into 800 1 times, resulting in a remainder of 160.
Put 1 as the next digit of the answer. 
Result so far: 43399.45781
Subtracting 640 from 800 leaves us 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.

Going ahead to step 14:
If we divide 1600 by 640, we get 2 and a remainder of 320.
The next digit of our result is 2. 
Result so far: 43399.457812
If we take 1280 away from 1600, we end up 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.

Step 15:
The number 640 fits into 3200 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 43399.4578125
If we subtract 3200 from 3200, 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.

Step 16:
640 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 43399.4578125
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.

Our division results in 43399.4578125 with a remaining 0.0.
