44101491 ÷ 640 
We want to figure out the number of times 44101491 can be divided by 640.

Step 1:
If we divide 4 by 640, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 640

Let's proceed to step 2:
640 goes into 44 0 times with a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Append the next digit (1) from the dividend to 44 and continue with: 441 / 640

Step 3:
640 can be fit into 441 0 times, resulting in a remainder of 441.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 441, we end up with 441.
Include the next digit (0) from the dividend after 441, then repeat: 4410 / 640

Moving on to step 4:
If we divide 4410 by 640, we get 6 and a remainder of 570.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 570 after subtracting 3840 from 4410.
Bring next digit (1) of the dividend behind the 570 and repeat the process: 5701 / 640

Going ahead to step 5:
The number 640 fits into 5701 8 times, leaving a remainder of 581.
Use 8 as the next digit of our solution. 
Result so far: 68.0
The remainder is 581 after subtracting 5120 from 5701.
Grab the next digit (4) from the dividend, add it to 581, then carry on: 5814 / 640

Moving on to step 6:
5814 divided by 640 is 9 with a remainder of 54.
Write down 9 as next digit of the result. 
Result so far: 689.0
Deduct 5760 from 5814 and we're left with 54.
Append the next digit (9) from the dividend to 54 and continue with: 549 / 640

On to step 7:
The number 640 fits into 549 0 times, leaving a remainder of 549.
Write down 0 as next digit of the result. 
Result so far: 6890.0
Subtracting 0 from 549 leaves us with 549.
Take the next digit (1) from the dividend and append it to 549, then repeat: 5491 / 640

Let's proceed to step 8:
640 goes into 5491 8 times with a remainder of 371.
Write down 8 as next digit of the result. 
Result so far: 68908.0
Subtract 5120 from 5491 to get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

On to step 9:
3710 divided by 640 is 5 with a remainder of 510.
Use 5 as the next digit of our solution. 
Result so far: 68908.5
Deduct 3200 from 3710 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 10:
640 goes into 5100 7 times with a remainder of 620.
Write down 7 as next digit of the result. 
Result so far: 68908.57
Subtract 4480 from 5100 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 11:
If we divide 6200 by 640, we get 9 and a remainder of 440.
The number 9 becomes the next digit in our result. 
Result so far: 68908.579
If we take 5760 away from 6200, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 12:
When dividing 4400 by 640, we get 6 with a remainder of 560.
The next digit of our result is 6. 
Result so far: 68908.5796
If we subtract 3840 from 4400, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 13:
5600 divided by 640 is 8 with a remainder of 480.
Use 8 as the next digit of our solution. 
Result so far: 68908.57968
Deduct 5120 from 5600 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.

On to step 14:
The number 640 fits into 4800 7 times, leaving a remainder of 320.
Put 7 as the next digit of the answer. 
Result so far: 68908.579687
The remainder is 320 after subtracting 4480 from 4800.
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 15:
The number 640 fits into 3200 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 68908.5796875
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.

Advancing to step 16:
When dividing 0 by 640, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 68908.5796875
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.

In conclusion, the division gives 68908.5796875 with a balance of 0.0.
