21032258 ÷ 583 
Our goal is to divide 21032258 by 583.

Going ahead to step 1:
If we divide 2 by 583, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 583

Step 2:
If we divide 21 by 583, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
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

Moving on to step 3:
583 goes into 210 0 times with a remainder of 210.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 210 after subtracting 0 from 210.
Include the next digit (3) from the dividend after 210, then repeat: 2103 / 583

Advancing to step 4:
2103 divided by 583 is 3 with a remainder of 354.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 354 after subtracting 1749 from 2103.
Bring next digit (2) of the dividend behind the 354 and repeat the process: 3542 / 583

Advancing to step 5:
When dividing 3542 by 583, we get 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 36.0
Subtract 3498 from 3542 to get 44.
Take the next digit (2) from the dividend and append it to 44, then repeat: 442 / 583

Going ahead to step 6:
If we divide 442 by 583, we get 0 and a remainder of 442.
Record the quotient 0 as the next digit in the result. 
Result so far: 360.0
Deduct 0 from 442 and we're left with 442.
Include the next digit (5) from the dividend after 442, then repeat: 4425 / 583

Going ahead to step 7:
583 can be fit into 4425 7 times, resulting in a remainder of 344.
The number 7 becomes the next digit in our result. 
Result so far: 3607.0
If we subtract 4081 from 4425, we get 344.
Grab the next digit (8) from the dividend, add it to 344, then carry on: 3448 / 583

Going ahead to step 8:
583 can be fit into 3448 5 times, resulting in a remainder of 533.
The next digit of our result is 5. 
Result so far: 36075.0
Deduct 2915 from 3448 and we're left with 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Advancing to step 9:
The number 583 fits into 5330 9 times, leaving a remainder of 83.
The next digit of our result is 9. 
Result so far: 36075.9
Subtract 5247 from 5330 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 10:
When dividing 830 by 583, we get 1 with a remainder of 247.
Use 1 as the next digit of our solution. 
Result so far: 36075.91
If we subtract 583 from 830, we get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Advancing to step 11:
583 goes into 2470 4 times with a remainder of 138.
Use 4 as the next digit of our solution. 
Result so far: 36075.914
If we take 2332 away from 2470, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 12:
The number 583 fits into 1380 2 times, leaving a remainder of 214.
Use 2 as the next digit of our solution. 
Result so far: 36075.9142
If we subtract 1166 from 1380, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 13:
583 can be fit into 2140 3 times, resulting in a remainder of 391.
Record the quotient 3 as the next digit in the result. 
Result so far: 36075.91423
If we subtract 1749 from 2140, we get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 14:
3910 divided by 583 is 6 with a remainder of 412.
Record the quotient 6 as the next digit in the result. 
Result so far: 36075.914236
Deduct 3498 from 3910 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

On to step 15:
The number 583 fits into 4120 7 times, leaving a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 36075.9142367
Subtracting 4081 from 4120 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 16:
390 divided by 583 is 0 with a remainder of 390.
Record the quotient 0 as the next digit in the result. 
Result so far: 36075.9142367
If we subtract 0 from 390, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

The final outcome is 36075.9142367, with a leftover of 3.9e-07.
