We divide 66990746 by 531
We're looking to find how many times 531 goes into 66990746.

Going ahead to step 1:
531 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 531

On to step 2:
531 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (9) of the dividend behind the 66 and repeat the process: 669 / 531

On to step 3:
669 divided by 531 is 1 with a remainder of 138.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 531 from 669 to get 138.
Append the next digit (9) from the dividend to 138 and continue with: 1389 / 531

Advancing to step 4:
If we divide 1389 by 531, we get 2 and a remainder of 327.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 1062 from 1389 leaves us with 327.
Include the next digit (0) from the dividend after 327, then repeat: 3270 / 531

Going ahead to step 5:
If we divide 3270 by 531, we get 6 and a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 126.0
Deduct 3186 from 3270 and we're left with 84.
Include the next digit (7) from the dividend after 84, then repeat: 847 / 531

Step 6:
531 goes into 847 1 times with a remainder of 316.
Record the quotient 1 as the next digit in the result. 
Result so far: 1261.0
If we take 531 away from 847, we end up with 316.
Grab the next digit (4) from the dividend, add it to 316, then carry on: 3164 / 531

Going ahead to step 7:
3164 divided by 531 is 5 with a remainder of 509.
Record the quotient 5 as the next digit in the result. 
Result so far: 12615.0
Subtract 2655 from 3164 to get 509.
Take the next digit (6) from the dividend and append it to 509, then repeat: 5096 / 531

Let's proceed to step 8:
When dividing 5096 by 531, we get 9 with a remainder of 317.
Record the quotient 9 as the next digit in the result. 
Result so far: 126159.0
If we take 4779 away from 5096, 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.

On to step 9:
531 can be fit into 3170 5 times, resulting in a remainder of 515.
Put 5 as the next digit of the answer. 
Result so far: 126159.5
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.

Advancing to step 10:
531 can be fit into 5150 9 times, resulting in a remainder of 371.
The next digit of our result is 9. 
Result so far: 126159.59
Subtracting 4779 from 5150 leaves us 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.

Step 11:
When dividing 3710 by 531, we get 6 with a remainder of 524.
The next digit of our result is 6. 
Result so far: 126159.596
Subtracting 3186 from 3710 leaves us with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Let's proceed to step 12:
When dividing 5240 by 531, we get 9 with a remainder of 461.
Record the quotient 9 as the next digit in the result. 
Result so far: 126159.5969
Deduct 4779 from 5240 and we're left with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Step 13:
If we divide 4610 by 531, we get 8 and a remainder of 362.
The number 8 becomes the next digit in our result. 
Result so far: 126159.59698
If we subtract 4248 from 4610, we get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Moving on to step 14:
When dividing 3620 by 531, we get 6 with a remainder of 434.
Use 6 as the next digit of our solution. 
Result so far: 126159.596986
The remainder is 434 after subtracting 3186 from 3620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Let's proceed to step 15:
531 goes into 4340 8 times with a remainder of 92.
The number 8 becomes the next digit in our result. 
Result so far: 126159.5969868
Deduct 4248 from 4340 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 16:
531 goes into 920 1 times with a remainder of 389.
Record the quotient 1 as the next digit in the result. 
Result so far: 126159.59698681
The remainder is 389 after subtracting 531 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Our division results in 126159.59698681 with a remaining 3.89e-07.
