Let's divide 21317867 by 531
We're looking to find how many times 531 goes into 21317867.

Let's proceed to step 1:
When dividing 2 by 531, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 531

Advancing to step 2:
21 divided by 531 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 531

Going ahead to step 3:
213 divided by 531 is 0 with a remainder of 213.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 213 leaves us with 213.
Fetch the next digit (1) from the dividend, attach it to 213 and continue: 2131 / 531

On to step 4:
If we divide 2131 by 531, we get 4 and a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 2124 from 2131, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 531

Advancing to step 5:
531 goes into 77 0 times with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Deduct 0 from 77 and we're left with 77.
Take the next digit (8) from the dividend and append it to 77, then repeat: 778 / 531

On to step 6:
If we divide 778 by 531, we get 1 and a remainder of 247.
Write down 1 as next digit of the result. 
Result so far: 401.0
Subtract 531 from 778 to get 247.
Include the next digit (6) from the dividend after 247, then repeat: 2476 / 531

Let's proceed to step 7:
531 goes into 2476 4 times with a remainder of 352.
The number 4 becomes the next digit in our result. 
Result so far: 4014.0
If we take 2124 away from 2476, we end up with 352.
Append the next digit (7) from the dividend to 352 and continue with: 3527 / 531

Moving on to step 8:
531 can be fit into 3527 6 times, resulting in a remainder of 341.
The number 6 becomes the next digit in our result. 
Result so far: 40146.0
Subtract 3186 from 3527 to get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Advancing to step 9:
3410 divided by 531 is 6 with a remainder of 224.
The next digit of our result is 6. 
Result so far: 40146.6
If we take 3186 away from 3410, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 10:
531 goes into 2240 4 times with a remainder of 116.
Use 4 as the next digit of our solution. 
Result so far: 40146.64
The remainder is 116 after subtracting 2124 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 11:
1160 divided by 531 is 2 with a remainder of 98.
The number 2 becomes the next digit in our result. 
Result so far: 40146.642
If we take 1062 away from 1160, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 12:
531 can be fit into 980 1 times, resulting in a remainder of 449.
Write down 1 as next digit of the result. 
Result so far: 40146.6421
Subtracting 531 from 980 leaves us with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Let's proceed to step 13:
If we divide 4490 by 531, we get 8 and a remainder of 242.
Use 8 as the next digit of our solution. 
Result so far: 40146.64218
If we take 4248 away from 4490, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Step 14:
531 goes into 2420 4 times with a remainder of 296.
The number 4 becomes the next digit in our result. 
Result so far: 40146.642184
Subtract 2124 from 2420 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 15:
2960 divided by 531 is 5 with a remainder of 305.
The number 5 becomes the next digit in our result. 
Result so far: 40146.6421845
If we subtract 2655 from 2960, we get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 16:
531 goes into 3050 5 times with a remainder of 395.
The next digit of our result is 5. 
Result so far: 40146.64218455
If we subtract 2655 from 3050, we get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

After the division, we end up with 40146.64218455 and a remainder of 3.95e-07.
