We divide 21685939 by 582
We want to figure out the number of times 21685939 can be divided by 582.

Step 1:
If we divide 2 by 582, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 582

Step 2:
When dividing 21 by 582, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 582

Moving on to step 3:
582 can be fit into 216 0 times, resulting in a remainder of 216.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 216 after subtracting 0 from 216.
Take the next digit (8) from the dividend and append it to 216, then repeat: 2168 / 582

Advancing to step 4:
If we divide 2168 by 582, we get 3 and a remainder of 422.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 1746 from 2168 and we're left with 422.
Bring next digit (5) of the dividend behind the 422 and repeat the process: 4225 / 582

Moving on to step 5:
When dividing 4225 by 582, we get 7 with a remainder of 151.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we subtract 4074 from 4225, we get 151.
Append the next digit (9) from the dividend to 151 and continue with: 1519 / 582

Moving on to step 6:
582 goes into 1519 2 times with a remainder of 355.
The next digit of our result is 2. 
Result so far: 372.0
If we subtract 1164 from 1519, we get 355.
Fetch the next digit (3) from the dividend, attach it to 355 and continue: 3553 / 582

Let's proceed to step 7:
3553 divided by 582 is 6 with a remainder of 61.
Put 6 as the next digit of the answer. 
Result so far: 3726.0
If we subtract 3492 from 3553, we get 61.
Bring next digit (9) of the dividend behind the 61 and repeat the process: 619 / 582

Step 8:
582 can be fit into 619 1 times, resulting in a remainder of 37.
The next digit of our result is 1. 
Result so far: 37261.0
The remainder is 37 after subtracting 582 from 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 9:
582 goes into 370 0 times with a remainder of 370.
Put 0 as the next digit of the answer. 
Result so far: 37261.0
If we subtract 0 from 370, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 10:
The number 582 fits into 3700 6 times, leaving a remainder of 208.
The next digit of our result is 6. 
Result so far: 37261.06
Subtracting 3492 from 3700 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 11:
582 can be fit into 2080 3 times, resulting in a remainder of 334.
Put 3 as the next digit of the answer. 
Result so far: 37261.063
Subtracting 1746 from 2080 leaves us with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Moving on to step 12:
582 goes into 3340 5 times with a remainder of 430.
The number 5 becomes the next digit in our result. 
Result so far: 37261.0635
Deduct 2910 from 3340 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 13:
582 goes into 4300 7 times with a remainder of 226.
Use 7 as the next digit of our solution. 
Result so far: 37261.06357
The remainder is 226 after subtracting 4074 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

On to step 14:
2260 divided by 582 is 3 with a remainder of 514.
Use 3 as the next digit of our solution. 
Result so far: 37261.063573
The remainder is 514 after subtracting 1746 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Advancing to step 15:
If we divide 5140 by 582, we get 8 and a remainder of 484.
Write down 8 as next digit of the result. 
Result so far: 37261.0635738
Subtracting 4656 from 5140 leaves us with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Let's proceed to step 16:
4840 divided by 582 is 8 with a remainder of 184.
Use 8 as the next digit of our solution. 
Result so far: 37261.06357388
Deduct 4656 from 4840 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

In conclusion, the division gives 37261.06357388 with a balance of 1.84e-07.
