We look at the division of 21973145 by 482 
Let's see how many times 482 fits into 21973145.

On to step 1:
If we divide 2 by 482, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 482

Moving on to step 2:
If we divide 21 by 482, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 482

Moving on to step 3:
The number 482 fits into 219 0 times, leaving a remainder of 219.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 219, we end up with 219.
Bring next digit (7) of the dividend behind the 219 and repeat the process: 2197 / 482

Let's proceed to step 4:
If we divide 2197 by 482, we get 4 and a remainder of 269.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 269 after subtracting 1928 from 2197.
Fetch the next digit (3) from the dividend, attach it to 269 and continue: 2693 / 482

Moving on to step 5:
The number 482 fits into 2693 5 times, leaving a remainder of 283.
The next digit of our result is 5. 
Result so far: 45.0
Subtracting 2410 from 2693 leaves us with 283.
Include the next digit (1) from the dividend after 283, then repeat: 2831 / 482

Moving on to step 6:
The number 482 fits into 2831 5 times, leaving a remainder of 421.
The next digit of our result is 5. 
Result so far: 455.0
Deduct 2410 from 2831 and we're left with 421.
Append the next digit (4) from the dividend to 421 and continue with: 4214 / 482

Moving on to step 7:
If we divide 4214 by 482, we get 8 and a remainder of 358.
Use 8 as the next digit of our solution. 
Result so far: 4558.0
Subtracting 3856 from 4214 leaves us with 358.
Append the next digit (5) from the dividend to 358 and continue with: 3585 / 482

Moving on to step 8:
When dividing 3585 by 482, we get 7 with a remainder of 211.
Put 7 as the next digit of the answer. 
Result so far: 45587.0
Deduct 3374 from 3585 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

On to step 9:
2110 divided by 482 is 4 with a remainder of 182.
Record the quotient 4 as the next digit in the result. 
Result so far: 45587.4
If we subtract 1928 from 2110, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 10:
482 goes into 1820 3 times with a remainder of 374.
The number 3 becomes the next digit in our result. 
Result so far: 45587.43
Subtracting 1446 from 1820 leaves us with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Going ahead to step 11:
482 goes into 3740 7 times with a remainder of 366.
Put 7 as the next digit of the answer. 
Result so far: 45587.437
If we take 3374 away from 3740, we end up with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Let's proceed to step 12:
482 can be fit into 3660 7 times, resulting in a remainder of 286.
Record the quotient 7 as the next digit in the result. 
Result so far: 45587.4377
Subtract 3374 from 3660 to get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

After the division, we end up with 45587.4377 and a remainder of 0.00286.
