We look at the division of 21885916 by 585 
We want to figure out the number of times 21885916 can be divided by 585.

Let's proceed to step 1:
When dividing 2 by 585, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 585

Advancing to step 2:
585 goes into 21 0 times with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 585

Let's proceed to step 3:
218 divided by 585 is 0 with a remainder of 218.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 218 and we're left with 218.
Bring next digit (8) of the dividend behind the 218 and repeat the process: 2188 / 585

Moving on to step 4:
If we divide 2188 by 585, we get 3 and a remainder of 433.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 1755 from 2188, we get 433.
Take the next digit (5) from the dividend and append it to 433, then repeat: 4335 / 585

Going ahead to step 5:
4335 divided by 585 is 7 with a remainder of 240.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtracting 4095 from 4335 leaves us with 240.
Append the next digit (9) from the dividend to 240 and continue with: 2409 / 585

Advancing to step 6:
When dividing 2409 by 585, we get 4 with a remainder of 69.
Write down 4 as next digit of the result. 
Result so far: 374.0
Deduct 2340 from 2409 and we're left with 69.
Grab the next digit (1) from the dividend, add it to 69, then carry on: 691 / 585

Moving on to step 7:
691 divided by 585 is 1 with a remainder of 106.
Write down 1 as next digit of the result. 
Result so far: 3741.0
If we subtract 585 from 691, we get 106.
Include the next digit (6) from the dividend after 106, then repeat: 1066 / 585

On to step 8:
1066 divided by 585 is 1 with a remainder of 481.
Write down 1 as next digit of the result. 
Result so far: 37411.0
Subtract 585 from 1066 to get 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Let's proceed to step 9:
585 goes into 4810 8 times with a remainder of 130.
Write down 8 as next digit of the result. 
Result so far: 37411.8
If we subtract 4680 from 4810, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 10:
When dividing 1300 by 585, we get 2 with a remainder of 130.
Put 2 as the next digit of the answer. 
Result so far: 37411.82
Subtract 1170 from 1300 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 11:
585 goes into 1300 2 times with a remainder of 130.
Use 2 as the next digit of our solution. 
Result so far: 37411.822
If we subtract 1170 from 1300, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

In conclusion, the division gives 37411.822 with a balance of 0.013.
