10921548 ÷ 640 
We want to figure out the number of times 10921548 can be divided by 640.

Moving on to step 1:
1 divided by 640 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 640

On to step 2:
10 divided by 640 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 640

Moving on to step 3:
640 goes into 109 0 times with a remainder of 109.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 109 leaves us with 109.
Take the next digit (2) from the dividend and append it to 109, then repeat: 1092 / 640

On to step 4:
1092 divided by 640 is 1 with a remainder of 452.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 640 from 1092, we get 452.
Append the next digit (1) from the dividend to 452 and continue with: 4521 / 640

Moving on to step 5:
The number 640 fits into 4521 7 times, leaving a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 41 after subtracting 4480 from 4521.
Include the next digit (5) from the dividend after 41, then repeat: 415 / 640

On to step 6:
415 divided by 640 is 0 with a remainder of 415.
Put 0 as the next digit of the answer. 
Result so far: 170.0
Subtracting 0 from 415 leaves us with 415.
Take the next digit (4) from the dividend and append it to 415, then repeat: 4154 / 640

Let's proceed to step 7:
640 goes into 4154 6 times with a remainder of 314.
Put 6 as the next digit of the answer. 
Result so far: 1706.0
If we subtract 3840 from 4154, we get 314.
Include the next digit (8) from the dividend after 314, then repeat: 3148 / 640

Step 8:
640 goes into 3148 4 times with a remainder of 588.
Write down 4 as next digit of the result. 
Result so far: 17064.0
If we subtract 2560 from 3148, we get 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Step 9:
When dividing 5880 by 640, we get 9 with a remainder of 120.
The number 9 becomes the next digit in our result. 
Result so far: 17064.9
The remainder is 120 after subtracting 5760 from 5880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 10:
When dividing 1200 by 640, we get 1 with a remainder of 560.
Write down 1 as next digit of the result. 
Result so far: 17064.91
Subtracting 640 from 1200 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 11:
640 goes into 5600 8 times with a remainder of 480.
The next digit of our result is 8. 
Result so far: 17064.918
The remainder is 480 after subtracting 5120 from 5600.
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 12:
When dividing 4800 by 640, we get 7 with a remainder of 320.
Record the quotient 7 as the next digit in the result. 
Result so far: 17064.9187
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 13:
3200 divided by 640 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 17064.91875
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 14:
When dividing 0 by 640, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17064.91875
The remainder is 0 after subtracting 0 from 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:
If we divide 0 by 640, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17064.91875
The remainder is 0 after subtracting 0 from 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 17064.91875 with a balance of 0.0.
