21111292 divided by 581 
We want to figure out the number of times 21111292 can be divided by 581.

Moving on to step 1:
If we divide 2 by 581, 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.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 581

On to step 2:
If we divide 21 by 581, 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 take 0 away from 21, we end up with 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 581

Advancing to step 3:
581 can be fit into 211 0 times, resulting in a remainder of 211.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 211 after subtracting 0 from 211.
Grab the next digit (1) from the dividend, add it to 211, then carry on: 2111 / 581

Going ahead to step 4:
The number 581 fits into 2111 3 times, leaving a remainder of 368.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 368 after subtracting 1743 from 2111.
Append the next digit (1) from the dividend to 368 and continue with: 3681 / 581

Let's proceed to step 5:
If we divide 3681 by 581, we get 6 and a remainder of 195.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
The remainder is 195 after subtracting 3486 from 3681.
Take the next digit (2) from the dividend and append it to 195, then repeat: 1952 / 581

Advancing to step 6:
581 can be fit into 1952 3 times, resulting in a remainder of 209.
The number 3 becomes the next digit in our result. 
Result so far: 363.0
If we take 1743 away from 1952, we end up with 209.
Grab the next digit (9) from the dividend, add it to 209, then carry on: 2099 / 581

Going ahead to step 7:
If we divide 2099 by 581, we get 3 and a remainder of 356.
The number 3 becomes the next digit in our result. 
Result so far: 3633.0
If we take 1743 away from 2099, we end up with 356.
Grab the next digit (2) from the dividend, add it to 356, then carry on: 3562 / 581

Moving on to step 8:
3562 divided by 581 is 6 with a remainder of 76.
Record the quotient 6 as the next digit in the result. 
Result so far: 36336.0
Subtracting 3486 from 3562 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 9:
581 can be fit into 760 1 times, resulting in a remainder of 179.
The next digit of our result is 1. 
Result so far: 36336.1
Subtract 581 from 760 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Step 10:
The number 581 fits into 1790 3 times, leaving a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 36336.13
If we subtract 1743 from 1790, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 11:
When dividing 470 by 581, we get 0 with a remainder of 470.
Write down 0 as next digit of the result. 
Result so far: 36336.13
Subtract 0 from 470 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

On to step 12:
4700 divided by 581 is 8 with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 36336.1308
The remainder is 52 after subtracting 4648 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 13:
The number 581 fits into 520 0 times, leaving a remainder of 520.
Write down 0 as next digit of the result. 
Result so far: 36336.1308
If we subtract 0 from 520, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 14:
The number 581 fits into 5200 8 times, leaving a remainder of 552.
The number 8 becomes the next digit in our result. 
Result so far: 36336.130808
Subtract 4648 from 5200 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Moving on to step 15:
If we divide 5520 by 581, we get 9 and a remainder of 291.
Write down 9 as next digit of the result. 
Result so far: 36336.1308089
If we subtract 5229 from 5520, we get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Let's proceed to step 16:
581 goes into 2910 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 36336.13080895
If we subtract 2905 from 2910, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 36336.13080895 and a remainder of 5e-09.
