We look at the division of 21628562 by 640 
We want to divide 21628562 by 640.

Let's proceed to step 1:
2 divided by 640 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 640

Going ahead to step 2:
When dividing 21 by 640, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 640

Advancing to step 3:
216 divided by 640 is 0 with a remainder of 216.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 216 to get 216.
Fetch the next digit (2) from the dividend, attach it to 216 and continue: 2162 / 640

Going ahead to step 4:
The number 640 fits into 2162 3 times, leaving a remainder of 242.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 1920 away from 2162, we end up with 242.
Include the next digit (8) from the dividend after 242, then repeat: 2428 / 640

On to step 5:
2428 divided by 640 is 3 with a remainder of 508.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we subtract 1920 from 2428, we get 508.
Fetch the next digit (5) from the dividend, attach it to 508 and continue: 5085 / 640

Step 6:
The number 640 fits into 5085 7 times, leaving a remainder of 605.
Write down 7 as next digit of the result. 
Result so far: 337.0
Subtracting 4480 from 5085 leaves us with 605.
Take the next digit (6) from the dividend and append it to 605, then repeat: 6056 / 640

On to step 7:
640 goes into 6056 9 times with a remainder of 296.
Record the quotient 9 as the next digit in the result. 
Result so far: 3379.0
If we take 5760 away from 6056, we end up with 296.
Take the next digit (2) from the dividend and append it to 296, then repeat: 2962 / 640

Let's proceed to step 8:
640 can be fit into 2962 4 times, resulting in a remainder of 402.
The number 4 becomes the next digit in our result. 
Result so far: 33794.0
Subtracting 2560 from 2962 leaves us with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Let's proceed to step 9:
If we divide 4020 by 640, we get 6 and a remainder of 180.
Record the quotient 6 as the next digit in the result. 
Result so far: 33794.6
If we subtract 3840 from 4020, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 10:
1800 divided by 640 is 2 with a remainder of 520.
Use 2 as the next digit of our solution. 
Result so far: 33794.62
The remainder is 520 after subtracting 1280 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 11:
The number 640 fits into 5200 8 times, leaving a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 33794.628
If we take 5120 away from 5200, we end up 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 12:
640 goes into 800 1 times with a remainder of 160.
Write down 1 as next digit of the result. 
Result so far: 33794.6281
If we take 640 away from 800, we end up 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 13:
If we divide 1600 by 640, we get 2 and a remainder of 320.
The number 2 becomes the next digit in our result. 
Result so far: 33794.62812
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.

Going ahead to step 14:
640 can be fit into 3200 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 33794.628125
If we take 3200 away from 3200, 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.

Moving on 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: 33794.628125
Subtract 0 from 0 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.

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: 33794.628125
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.

Our division results in 33794.628125 with a remaining 0.0.
