16705457 ÷ 531 
Our goal is to divide 16705457 by 531.

Going ahead to step 1:
531 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 531

On to step 2:
531 goes into 16 0 times with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Grab the next digit (7) from the dividend, add it to 16, then carry on: 167 / 531

Step 3:
When dividing 167 by 531, we get 0 with a remainder of 167.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 167 leaves us with 167.
Take the next digit (0) from the dividend and append it to 167, then repeat: 1670 / 531

Going ahead to step 4:
The number 531 fits into 1670 3 times, leaving a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 1593 away from 1670, we end up with 77.
Include the next digit (5) from the dividend after 77, then repeat: 775 / 531

Moving on to step 5:
775 divided by 531 is 1 with a remainder of 244.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtract 531 from 775 to get 244.
Grab the next digit (4) from the dividend, add it to 244, then carry on: 2444 / 531

On to step 6:
The number 531 fits into 2444 4 times, leaving a remainder of 320.
Write down 4 as next digit of the result. 
Result so far: 314.0
If we subtract 2124 from 2444, we get 320.
Grab the next digit (5) from the dividend, add it to 320, then carry on: 3205 / 531

Step 7:
531 goes into 3205 6 times with a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 3146.0
Deduct 3186 from 3205 and we're left with 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 531

Moving on to step 8:
If we divide 197 by 531, we get 0 and a remainder of 197.
The next digit of our result is 0. 
Result so far: 31460.0
Subtracting 0 from 197 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Going ahead to step 9:
531 can be fit into 1970 3 times, resulting in a remainder of 377.
Write down 3 as next digit of the result. 
Result so far: 31460.3
Subtract 1593 from 1970 to get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Going ahead to step 10:
3770 divided by 531 is 7 with a remainder of 53.
The next digit of our result is 7. 
Result so far: 31460.37
Subtract 3717 from 3770 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 11:
The number 531 fits into 530 0 times, leaving a remainder of 530.
The next digit of our result is 0. 
Result so far: 31460.37
Deduct 0 from 530 and we're left with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Let's proceed to step 12:
531 goes into 5300 9 times with a remainder of 521.
The next digit of our result is 9. 
Result so far: 31460.3709
The remainder is 521 after subtracting 4779 from 5300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

Moving on to step 13:
When dividing 5210 by 531, we get 9 with a remainder of 431.
The number 9 becomes the next digit in our result. 
Result so far: 31460.37099
Subtracting 4779 from 5210 leaves us with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

After the division, we end up with 31460.37099 and a remainder of 0.000431.
