Let's see how many times 640 fits into 43894103.

Advancing to step 1:
When dividing 4 by 640, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 640

Moving on to step 2:
If we divide 43 by 640, we get 0 and a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 640

Advancing to step 3:
438 divided by 640 is 0 with a remainder of 438.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 438, we end up with 438.
Include the next digit (9) from the dividend after 438, then repeat: 4389 / 640

Step 4:
When dividing 4389 by 640, we get 6 with a remainder of 549.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 549 after subtracting 3840 from 4389.
Fetch the next digit (4) from the dividend, attach it to 549 and continue: 5494 / 640

Step 5:
5494 divided by 640 is 8 with a remainder of 374.
Put 8 as the next digit of the answer. 
Result so far: 68.0
Deduct 5120 from 5494 and we're left with 374.
Include the next digit (1) from the dividend after 374, then repeat: 3741 / 640

Moving on to step 6:
When dividing 3741 by 640, we get 5 with a remainder of 541.
Use 5 as the next digit of our solution. 
Result so far: 685.0
Subtracting 3200 from 3741 leaves us with 541.
Include the next digit (0) from the dividend after 541, then repeat: 5410 / 640

Advancing to step 7:
640 can be fit into 5410 8 times, resulting in a remainder of 290.
Use 8 as the next digit of our solution. 
Result so far: 6858.0
Subtracting 5120 from 5410 leaves us with 290.
Include the next digit (3) from the dividend after 290, then repeat: 2903 / 640

Going ahead to step 8:
If we divide 2903 by 640, we get 4 and a remainder of 343.
Use 4 as the next digit of our solution. 
Result so far: 68584.0
Subtracting 2560 from 2903 leaves us with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

On to step 9:
If we divide 3430 by 640, we get 5 and a remainder of 230.
The next digit of our result is 5. 
Result so far: 68584.5
If we subtract 3200 from 3430, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 10:
When dividing 2300 by 640, we get 3 with a remainder of 380.
The next digit of our result is 3. 
Result so far: 68584.53
The remainder is 380 after subtracting 1920 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 11:
If we divide 3800 by 640, we get 5 and a remainder of 600.
Put 5 as the next digit of the answer. 
Result so far: 68584.535
Deduct 3200 from 3800 and we're left 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.

Step 12:
When dividing 6000 by 640, we get 9 with a remainder of 240.
Record the quotient 9 as the next digit in the result. 
Result so far: 68584.5359
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.

Step 13:
If we divide 2400 by 640, we get 3 and a remainder of 480.
Put 3 as the next digit of the answer. 
Result so far: 68584.53593
Deduct 1920 from 2400 and we're left 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.

Advancing to step 14:
When dividing 4800 by 640, we get 7 with a remainder of 320.
Put 7 as the next digit of the answer. 
Result so far: 68584.535937
Subtracting 4480 from 4800 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.

Step 15:
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: 68584.5359375
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.

On to step 16:
If we divide 0 by 640, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 68584.5359375
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.

In conclusion, the division gives 68584.5359375 with a balance of 0.0.
