21003604 ÷ 482 
We want to divide 21003604 by 482.

Step 1:
482 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 482

Going ahead to step 2:
If we divide 21 by 482, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 482

Let's proceed to step 3:
482 goes into 210 0 times with a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 210 to get 210.
Fetch the next digit (0) from the dividend, attach it to 210 and continue: 2100 / 482

On to step 4:
482 goes into 2100 4 times with a remainder of 172.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 1928 from 2100 and we're left with 172.
Take the next digit (3) from the dividend and append it to 172, then repeat: 1723 / 482

Step 5:
The number 482 fits into 1723 3 times, leaving a remainder of 277.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Deduct 1446 from 1723 and we're left with 277.
Grab the next digit (6) from the dividend, add it to 277, then carry on: 2776 / 482

Going ahead to step 6:
The number 482 fits into 2776 5 times, leaving a remainder of 366.
The number 5 becomes the next digit in our result. 
Result so far: 435.0
Deduct 2410 from 2776 and we're left with 366.
Take the next digit (0) from the dividend and append it to 366, then repeat: 3660 / 482

Let's proceed to step 7:
When dividing 3660 by 482, we get 7 with a remainder of 286.
Record the quotient 7 as the next digit in the result. 
Result so far: 4357.0
Subtract 3374 from 3660 to get 286.
Include the next digit (4) from the dividend after 286, then repeat: 2864 / 482

Let's proceed to step 8:
The number 482 fits into 2864 5 times, leaving a remainder of 454.
Put 5 as the next digit of the answer. 
Result so far: 43575.0
The remainder is 454 after subtracting 2410 from 2864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Moving on to step 9:
482 can be fit into 4540 9 times, resulting in a remainder of 202.
Record the quotient 9 as the next digit in the result. 
Result so far: 43575.9
Subtracting 4338 from 4540 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 10:
When dividing 2020 by 482, we get 4 with a remainder of 92.
Put 4 as the next digit of the answer. 
Result so far: 43575.94
Deduct 1928 from 2020 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 11:
482 goes into 920 1 times with a remainder of 438.
Use 1 as the next digit of our solution. 
Result so far: 43575.941
If we subtract 482 from 920, we get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Going ahead to step 12:
When dividing 4380 by 482, we get 9 with a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 43575.9419
If we subtract 4338 from 4380, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 13:
If we divide 420 by 482, we get 0 and a remainder of 420.
Write down 0 as next digit of the result. 
Result so far: 43575.9419
Deduct 0 from 420 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 14:
The number 482 fits into 4200 8 times, leaving a remainder of 344.
Record the quotient 8 as the next digit in the result. 
Result so far: 43575.941908
If we take 3856 away from 4200, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 15:
When dividing 3440 by 482, we get 7 with a remainder of 66.
The next digit of our result is 7. 
Result so far: 43575.9419087
If we take 3374 away from 3440, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 16:
482 goes into 660 1 times with a remainder of 178.
The number 1 becomes the next digit in our result. 
Result so far: 43575.94190871
Subtracting 482 from 660 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

The final result is 43575.94190871 with a remainder of 1.78e-07.
