We look at the division of 21635247 by 480 
We want to divide 21635247 by 480.

Let's proceed to step 1:
The number 480 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 480

Advancing to step 2:
21 divided by 480 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 480

Moving on to step 3:
480 goes into 216 0 times with a remainder of 216.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 216, we get 216.
Take the next digit (3) from the dividend and append it to 216, then repeat: 2163 / 480

Moving on to step 4:
480 can be fit into 2163 4 times, resulting in a remainder of 243.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 1920 away from 2163, we end up with 243.
Grab the next digit (5) from the dividend, add it to 243, then carry on: 2435 / 480

Step 5:
480 goes into 2435 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Deduct 2400 from 2435 and we're left with 35.
Take the next digit (2) from the dividend and append it to 35, then repeat: 352 / 480

Let's proceed to step 6:
352 divided by 480 is 0 with a remainder of 352.
The number 0 becomes the next digit in our result. 
Result so far: 450.0
Deduct 0 from 352 and we're left with 352.
Include the next digit (4) from the dividend after 352, then repeat: 3524 / 480

Moving on to step 7:
480 can be fit into 3524 7 times, resulting in a remainder of 164.
Write down 7 as next digit of the result. 
Result so far: 4507.0
If we subtract 3360 from 3524, we get 164.
Append the next digit (7) from the dividend to 164 and continue with: 1647 / 480

Step 8:
The number 480 fits into 1647 3 times, leaving a remainder of 207.
Use 3 as the next digit of our solution. 
Result so far: 45073.0
Deduct 1440 from 1647 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Step 9:
480 can be fit into 2070 4 times, resulting in a remainder of 150.
The next digit of our result is 4. 
Result so far: 45073.4
Subtract 1920 from 2070 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 10:
480 goes into 1500 3 times with a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 45073.43
If we subtract 1440 from 1500, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
480 goes into 600 1 times with a remainder of 120.
The number 1 becomes the next digit in our result. 
Result so far: 45073.431
Deduct 480 from 600 and we're left with 120.
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 12:
If we divide 1200 by 480, we get 2 and a remainder of 240.
The number 2 becomes the next digit in our result. 
Result so far: 45073.4312
If we subtract 960 from 1200, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 13:
2400 divided by 480 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 45073.43125
If we subtract 2400 from 2400, we 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.

Moving on to step 14:
0 divided by 480 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 45073.43125
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.

On to step 15:
The number 480 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 45073.43125
If we subtract 0 from 0, we 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.

The quotient of the division is 45073.43125, and the remainder is 0.0.
