We look at the division of 21275285 by 583 
We're looking to find how many times 583 goes into 21275285.

Moving on to step 1:
If we divide 2 by 583, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 583

Advancing to step 2:
If we divide 21 by 583, we get 0 and a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 583

Advancing to step 3:
583 can be fit into 212 0 times, resulting in a remainder of 212.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 212 to get 212.
Append the next digit (7) from the dividend to 212 and continue with: 2127 / 583

On to step 4:
If we divide 2127 by 583, we get 3 and a remainder of 378.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 1749 from 2127, we get 378.
Include the next digit (5) from the dividend after 378, then repeat: 3785 / 583

On to step 5:
The number 583 fits into 3785 6 times, leaving a remainder of 287.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Deduct 3498 from 3785 and we're left with 287.
Append the next digit (2) from the dividend to 287 and continue with: 2872 / 583

Let's proceed to step 6:
583 can be fit into 2872 4 times, resulting in a remainder of 540.
The number 4 becomes the next digit in our result. 
Result so far: 364.0
Subtracting 2332 from 2872 leaves us with 540.
Bring next digit (8) of the dividend behind the 540 and repeat the process: 5408 / 583

Advancing to step 7:
When dividing 5408 by 583, we get 9 with a remainder of 161.
Put 9 as the next digit of the answer. 
Result so far: 3649.0
Deduct 5247 from 5408 and we're left with 161.
Include the next digit (5) from the dividend after 161, then repeat: 1615 / 583

Step 8:
When dividing 1615 by 583, we get 2 with a remainder of 449.
Put 2 as the next digit of the answer. 
Result so far: 36492.0
If we take 1166 away from 1615, we end up with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Going ahead to step 9:
When dividing 4490 by 583, we get 7 with a remainder of 409.
The next digit of our result is 7. 
Result so far: 36492.7
Subtract 4081 from 4490 to get 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Let's proceed to step 10:
4090 divided by 583 is 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 36492.77
Subtracting 4081 from 4090 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The quotient of the division is 36492.77, and the remainder is 0.009.
