21147423 divided by 531 
Let's see how many times 531 fits into 21147423.

Let's proceed to step 1:
2 divided by 531 is 0 with 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.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 531

Step 2:
531 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 531

Let's proceed to step 3:
211 divided by 531 is 0 with a remainder of 211.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 211 and we're left with 211.
Bring next digit (4) of the dividend behind the 211 and repeat the process: 2114 / 531

Going ahead to step 4:
If we divide 2114 by 531, we get 3 and a remainder of 521.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 1593 away from 2114, we end up with 521.
Bring next digit (7) of the dividend behind the 521 and repeat the process: 5217 / 531

Step 5:
When dividing 5217 by 531, we get 9 with a remainder of 438.
The next digit of our result is 9. 
Result so far: 39.0
The remainder is 438 after subtracting 4779 from 5217.
Bring next digit (4) of the dividend behind the 438 and repeat the process: 4384 / 531

Step 6:
4384 divided by 531 is 8 with a remainder of 136.
Put 8 as the next digit of the answer. 
Result so far: 398.0
Subtracting 4248 from 4384 leaves us with 136.
Take the next digit (2) from the dividend and append it to 136, then repeat: 1362 / 531

On to step 7:
1362 divided by 531 is 2 with a remainder of 300.
Write down 2 as next digit of the result. 
Result so far: 3982.0
Deduct 1062 from 1362 and we're left with 300.
Grab the next digit (3) from the dividend, add it to 300, then carry on: 3003 / 531

On to step 8:
When dividing 3003 by 531, we get 5 with a remainder of 348.
The number 5 becomes the next digit in our result. 
Result so far: 39825.0
If we subtract 2655 from 3003, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Going ahead to step 9:
531 goes into 3480 6 times with a remainder of 294.
The number 6 becomes the next digit in our result. 
Result so far: 39825.6
Subtract 3186 from 3480 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Let's proceed to step 10:
The number 531 fits into 2940 5 times, leaving a remainder of 285.
The next digit of our result is 5. 
Result so far: 39825.65
Deduct 2655 from 2940 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 11:
531 goes into 2850 5 times with a remainder of 195.
Put 5 as the next digit of the answer. 
Result so far: 39825.655
Subtracting 2655 from 2850 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

The quotient of the division is 39825.655, and the remainder is 0.0195.
