831712 ÷ 66 
We're looking to find how many times 66 goes into 831712.

Step 1:
If we divide 8 by 66, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 66

Advancing to step 2:
If we divide 83 by 66, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 17 after subtracting 66 from 83.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 66

Advancing to step 3:
171 divided by 66 is 2 with a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 132 from 171 to get 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 66

Step 4:
The number 66 fits into 397 6 times, leaving a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 126.0
Subtract 396 from 397 to get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 66

Going ahead to step 5:
The number 66 fits into 11 0 times, leaving a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 1260.0
If we subtract 0 from 11, we get 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 66

On to step 6:
112 divided by 66 is 1 with a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 12601.0
If we subtract 66 from 112, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 7:
66 can be fit into 460 6 times, resulting in a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 12601.6
Subtract 396 from 460 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 8:
When dividing 640 by 66, we get 9 with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 12601.69
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 9:
66 goes into 460 6 times with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 12601.696
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
640 divided by 66 is 9 with a remainder of 46.
The next digit of our result is 9. 
Result so far: 12601.6969
Deduct 594 from 640 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
66 goes into 460 6 times with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 12601.69696
Subtract 396 from 460 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 12:
If we divide 640 by 66, we get 9 and a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 12601.696969
The remainder is 46 after subtracting 594 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 13:
460 divided by 66 is 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 12601.6969696
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
The number 66 fits into 640 9 times, leaving a remainder of 46.
The next digit of our result is 9. 
Result so far: 12601.69696969
Deduct 594 from 640 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

After the division, we end up with 12601.69696969 and a remainder of 4.6e-08.
