We look at the division of 21617430 by 480 
We want to figure out the number of times 21617430 can be divided by 480.

Let's proceed to step 1:
480 can be fit into 2 0 times, resulting in 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.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 480

On to step 2:
The number 480 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 480

Moving on to step 3:
If we divide 216 by 480, we get 0 and a remainder of 216.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 216, we get 216.
Grab the next digit (1) from the dividend, add it to 216, then carry on: 2161 / 480

Let's proceed to step 4:
2161 divided by 480 is 4 with a remainder of 241.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 1920 from 2161, we get 241.
Include the next digit (7) from the dividend after 241, then repeat: 2417 / 480

Advancing to step 5:
2417 divided by 480 is 5 with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtracting 2400 from 2417 leaves us with 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 480

Let's proceed to step 6:
480 goes into 174 0 times with a remainder of 174.
Use 0 as the next digit of our solution. 
Result so far: 450.0
The remainder is 174 after subtracting 0 from 174.
Append the next digit (3) from the dividend to 174 and continue with: 1743 / 480

Step 7:
480 goes into 1743 3 times with a remainder of 303.
Use 3 as the next digit of our solution. 
Result so far: 4503.0
Subtract 1440 from 1743 to get 303.
Bring next digit (0) of the dividend behind the 303 and repeat the process: 3030 / 480

Let's proceed to step 8:
The number 480 fits into 3030 6 times, leaving a remainder of 150.
Use 6 as the next digit of our solution. 
Result so far: 45036.0
If we subtract 2880 from 3030, we 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.

Advancing to step 9:
The number 480 fits into 1500 3 times, leaving a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 45036.3
If we take 1440 away from 1500, we end up with 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 10:
480 goes into 600 1 times with a remainder of 120.
Put 1 as the next digit of the answer. 
Result so far: 45036.31
If we take 480 away from 600, we end up 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.

Step 11:
480 goes into 1200 2 times with a remainder of 240.
The next digit of our result is 2. 
Result so far: 45036.312
Subtracting 960 from 1200 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 12:
The number 480 fits into 2400 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 45036.3125
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.

Advancing to step 13:
The number 480 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 45036.3125
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.

Going ahead to step 14:
The number 480 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 45036.3125
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.

Our division results in 45036.3125 with a remaining 0.0.
