843431 divided by 66 
We want to divide 843431 by 66.

On to step 1:
8 divided by 66 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 66

Step 2:
If we divide 84 by 66, we get 1 and a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 66 from 84, we get 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 66

Going ahead to step 3:
If we divide 183 by 66, we get 2 and a remainder of 51.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 51 after subtracting 132 from 183.
Append the next digit (4) from the dividend to 51 and continue with: 514 / 66

Step 4:
The number 66 fits into 514 7 times, leaving a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 127.0
The remainder is 52 after subtracting 462 from 514.
Append the next digit (3) from the dividend to 52 and continue with: 523 / 66

Going ahead to step 5:
523 divided by 66 is 7 with a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 1277.0
Subtracting 462 from 523 leaves us with 61.
Include the next digit (1) from the dividend after 61, then repeat: 611 / 66

Let's proceed to step 6:
The number 66 fits into 611 9 times, leaving a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 12779.0
Subtracting 594 from 611 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
The number 66 fits into 170 2 times, leaving a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 12779.2
Deduct 132 from 170 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 8:
66 goes into 380 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 12779.25
If we subtract 330 from 380, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
66 can be fit into 500 7 times, resulting in a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 12779.257
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
380 divided by 66 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 12779.2575
The remainder is 50 after subtracting 330 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
500 divided by 66 is 7 with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 12779.25757
If we subtract 462 from 500, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
380 divided by 66 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 12779.257575
If we take 330 away from 380, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
The number 66 fits into 500 7 times, leaving a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 12779.2575757
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 14:
The number 66 fits into 380 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 12779.25757575
If we subtract 330 from 380, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 12779.25757575, and the remainder is 5e-08.
