Let's divide 16629380 by 640
We want to figure out the number of times 16629380 can be divided by 640.

Moving on to step 1:
640 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 640

Let's proceed to step 2:
640 can be fit into 16 0 times, resulting in a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 640

Let's proceed to step 3:
640 can be fit into 166 0 times, resulting in a remainder of 166.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 166 after subtracting 0 from 166.
Grab the next digit (2) from the dividend, add it to 166, then carry on: 1662 / 640

On to step 4:
When dividing 1662 by 640, we get 2 with a remainder of 382.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1280 from 1662 and we're left with 382.
Grab the next digit (9) from the dividend, add it to 382, then carry on: 3829 / 640

Let's proceed to step 5:
3829 divided by 640 is 5 with a remainder of 629.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtract 3200 from 3829 to get 629.
Bring next digit (3) of the dividend behind the 629 and repeat the process: 6293 / 640

Going ahead to step 6:
640 goes into 6293 9 times with a remainder of 533.
Put 9 as the next digit of the answer. 
Result so far: 259.0
Deduct 5760 from 6293 and we're left with 533.
Fetch the next digit (8) from the dividend, attach it to 533 and continue: 5338 / 640

Moving on to step 7:
5338 divided by 640 is 8 with a remainder of 218.
Put 8 as the next digit of the answer. 
Result so far: 2598.0
Deduct 5120 from 5338 and we're left with 218.
Include the next digit (0) from the dividend after 218, then repeat: 2180 / 640

Let's proceed to step 8:
640 goes into 2180 3 times with a remainder of 260.
Use 3 as the next digit of our solution. 
Result so far: 25983.0
Subtracting 1920 from 2180 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 9:
640 can be fit into 2600 4 times, resulting in a remainder of 40.
The next digit of our result is 4. 
Result so far: 25983.4
If we take 2560 away from 2600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
640 can be fit into 400 0 times, resulting in a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 25983.4
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 11:
If we divide 4000 by 640, we get 6 and a remainder of 160.
Use 6 as the next digit of our solution. 
Result so far: 25983.406
Subtracting 3840 from 4000 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.

Let's proceed to step 12:
640 goes into 1600 2 times with a remainder of 320.
Put 2 as the next digit of the answer. 
Result so far: 25983.4062
Deduct 1280 from 1600 and we're left 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.

Let's proceed to step 13:
The number 640 fits into 3200 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 25983.40625
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.

Moving on to step 14:
If we divide 0 by 640, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 25983.40625
Deduct 0 from 0 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.

Going ahead to step 15:
0 divided by 640 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25983.40625
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.

After the division, we end up with 25983.40625 and a remainder of 0.0.
