We look at the division of 21050412 by 583 
Let's see how many times 583 fits into 21050412.

Step 1:
583 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
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 583

On to step 2:
583 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 583

Advancing to step 3:
If we divide 210 by 583, we get 0 and a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 210 after subtracting 0 from 210.
Append the next digit (5) from the dividend to 210 and continue with: 2105 / 583

On to step 4:
583 goes into 2105 3 times with a remainder of 356.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 356 after subtracting 1749 from 2105.
Fetch the next digit (0) from the dividend, attach it to 356 and continue: 3560 / 583

Going ahead to step 5:
583 can be fit into 3560 6 times, resulting in a remainder of 62.
The next digit of our result is 6. 
Result so far: 36.0
If we take 3498 away from 3560, we end up with 62.
Grab the next digit (4) from the dividend, add it to 62, then carry on: 624 / 583

Let's proceed to step 6:
583 goes into 624 1 times with a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 361.0
If we subtract 583 from 624, we get 41.
Include the next digit (1) from the dividend after 41, then repeat: 411 / 583

Advancing to step 7:
583 goes into 411 0 times with a remainder of 411.
Write down 0 as next digit of the result. 
Result so far: 3610.0
If we subtract 0 from 411, we get 411.
Bring next digit (2) of the dividend behind the 411 and repeat the process: 4112 / 583

Moving on to step 8:
4112 divided by 583 is 7 with a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 36107.0
Deduct 4081 from 4112 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
310 divided by 583 is 0 with a remainder of 310.
Write down 0 as next digit of the result. 
Result so far: 36107.0
If we take 0 away from 310, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 10:
3100 divided by 583 is 5 with a remainder of 185.
Record the quotient 5 as the next digit in the result. 
Result so far: 36107.05
Subtract 2915 from 3100 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 11:
583 can be fit into 1850 3 times, resulting in a remainder of 101.
Put 3 as the next digit of the answer. 
Result so far: 36107.053
Deduct 1749 from 1850 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 12:
The number 583 fits into 1010 1 times, leaving a remainder of 427.
Record the quotient 1 as the next digit in the result. 
Result so far: 36107.0531
If we take 583 away from 1010, we end up with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

On to step 13:
583 goes into 4270 7 times with a remainder of 189.
Record the quotient 7 as the next digit in the result. 
Result so far: 36107.05317
Deduct 4081 from 4270 and we're left with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Let's proceed to step 14:
If we divide 1890 by 583, we get 3 and a remainder of 141.
The next digit of our result is 3. 
Result so far: 36107.053173
If we take 1749 away from 1890, we end up with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Let's proceed to step 15:
If we divide 1410 by 583, we get 2 and a remainder of 244.
Put 2 as the next digit of the answer. 
Result so far: 36107.0531732
The remainder is 244 after subtracting 1166 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Moving on to step 16:
583 can be fit into 2440 4 times, resulting in a remainder of 108.
Use 4 as the next digit of our solution. 
Result so far: 36107.05317324
If we take 2332 away from 2440, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The quotient of the division is 36107.05317324, and the remainder is 1.08e-07.
