We look at the division of 842813 by 66 
We want to figure out the number of times 842813 can be divided by 66.

Step 1:
8 divided by 66 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 66

Advancing to step 2:
If we divide 84 by 66, we get 1 and a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 18 after subtracting 66 from 84.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 66

Step 3:
66 goes into 182 2 times with a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 132 from 182 to get 50.
Fetch the next digit (8) from the dividend, attach it to 50 and continue: 508 / 66

Step 4:
When dividing 508 by 66, we get 7 with a remainder of 46.
Put 7 as the next digit of the answer. 
Result so far: 127.0
If we subtract 462 from 508, we get 46.
Fetch the next digit (1) from the dividend, attach it to 46 and continue: 461 / 66

On to step 5:
If we divide 461 by 66, we get 6 and a remainder of 65.
The number 6 becomes the next digit in our result. 
Result so far: 1276.0
Deduct 396 from 461 and we're left with 65.
Include the next digit (3) from the dividend after 65, then repeat: 653 / 66

Step 6:
If we divide 653 by 66, we get 9 and a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 12769.0
Deduct 594 from 653 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 7:
66 can be fit into 590 8 times, resulting in a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 12769.8
Deduct 528 from 590 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 8:
The number 66 fits into 620 9 times, leaving a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 12769.89
If we subtract 594 from 620, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
260 divided by 66 is 3 with a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 12769.893
Subtracting 198 from 260 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 10:
The number 66 fits into 620 9 times, leaving a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 12769.8939
If we take 594 away from 620, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
66 can be fit into 260 3 times, resulting in a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 12769.89393
The remainder is 62 after subtracting 198 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 12:
When dividing 620 by 66, we get 9 with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 12769.893939
Subtracting 594 from 620 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 13:
66 can be fit into 260 3 times, resulting in a remainder of 62.
The next digit of our result is 3. 
Result so far: 12769.8939393
Deduct 198 from 260 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 14:
The number 66 fits into 620 9 times, leaving a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 12769.89393939
If we subtract 594 from 620, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 12769.89393939, with a leftover of 2.6e-08.
