66933686 divided by 531 
We want to figure out the number of times 66933686 can be divided by 531.

Step 1:
6 divided by 531 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 531

Going ahead to step 2:
The number 531 fits into 66 0 times, leaving a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Take the next digit (9) from the dividend and append it to 66, then repeat: 669 / 531

On to step 3:
669 divided by 531 is 1 with a remainder of 138.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 138 after subtracting 531 from 669.
Grab the next digit (3) from the dividend, add it to 138, then carry on: 1383 / 531

Step 4:
1383 divided by 531 is 2 with a remainder of 321.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1062 from 1383 to get 321.
Include the next digit (3) from the dividend after 321, then repeat: 3213 / 531

Let's proceed to step 5:
531 goes into 3213 6 times with a remainder of 27.
Use 6 as the next digit of our solution. 
Result so far: 126.0
The remainder is 27 after subtracting 3186 from 3213.
Include the next digit (6) from the dividend after 27, then repeat: 276 / 531

Let's proceed to step 6:
531 goes into 276 0 times with a remainder of 276.
Use 0 as the next digit of our solution. 
Result so far: 1260.0
If we take 0 away from 276, we end up with 276.
Bring next digit (8) of the dividend behind the 276 and repeat the process: 2768 / 531

Let's proceed to step 7:
If we divide 2768 by 531, we get 5 and a remainder of 113.
Put 5 as the next digit of the answer. 
Result so far: 12605.0
Subtract 2655 from 2768 to get 113.
Include the next digit (6) from the dividend after 113, then repeat: 1136 / 531

Moving on to step 8:
531 can be fit into 1136 2 times, resulting in a remainder of 74.
The number 2 becomes the next digit in our result. 
Result so far: 126052.0
If we subtract 1062 from 1136, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 9:
531 goes into 740 1 times with a remainder of 209.
Use 1 as the next digit of our solution. 
Result so far: 126052.1
Deduct 531 from 740 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Advancing to step 10:
The number 531 fits into 2090 3 times, leaving a remainder of 497.
Put 3 as the next digit of the answer. 
Result so far: 126052.13
If we subtract 1593 from 2090, we get 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Let's proceed to step 11:
When dividing 4970 by 531, we get 9 with a remainder of 191.
The next digit of our result is 9. 
Result so far: 126052.139
If we take 4779 away from 4970, we end up with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Moving on to step 12:
531 goes into 1910 3 times with a remainder of 317.
Record the quotient 3 as the next digit in the result. 
Result so far: 126052.1393
If we take 1593 away from 1910, we end up with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Step 13:
3170 divided by 531 is 5 with a remainder of 515.
The number 5 becomes the next digit in our result. 
Result so far: 126052.13935
Subtract 2655 from 3170 to get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Moving on to step 14:
If we divide 5150 by 531, we get 9 and a remainder of 371.
The number 9 becomes the next digit in our result. 
Result so far: 126052.139359
Deduct 4779 from 5150 and we're left with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Moving on to step 15:
3710 divided by 531 is 6 with a remainder of 524.
Use 6 as the next digit of our solution. 
Result so far: 126052.1393596
Subtract 3186 from 3710 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Going ahead to step 16:
5240 divided by 531 is 9 with a remainder of 461.
Write down 9 as next digit of the result. 
Result so far: 126052.13935969
Subtract 4779 from 5240 to get 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

After the division, we end up with 126052.13935969 and a remainder of 4.61e-07.
