66383485 ÷ 843 
We want to figure out the number of times 66383485 can be divided by 843.

Let's proceed to step 1:
843 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 843

Going ahead to step 2:
If we divide 66 by 843, we get 0 and a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 843

Going ahead to step 3:
The number 843 fits into 663 0 times, leaving a remainder of 663.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 663, we end up with 663.
Fetch the next digit (8) from the dividend, attach it to 663 and continue: 6638 / 843

On to step 4:
843 goes into 6638 7 times with a remainder of 737.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 5901 from 6638 to get 737.
Fetch the next digit (3) from the dividend, attach it to 737 and continue: 7373 / 843

Let's proceed to step 5:
When dividing 7373 by 843, we get 8 with a remainder of 629.
Put 8 as the next digit of the answer. 
Result so far: 78.0
If we take 6744 away from 7373, we end up with 629.
Bring next digit (4) of the dividend behind the 629 and repeat the process: 6294 / 843

Advancing to step 6:
When dividing 6294 by 843, we get 7 with a remainder of 393.
Write down 7 as next digit of the result. 
Result so far: 787.0
Subtract 5901 from 6294 to get 393.
Append the next digit (8) from the dividend to 393 and continue with: 3938 / 843

Let's proceed to step 7:
The number 843 fits into 3938 4 times, leaving a remainder of 566.
The next digit of our result is 4. 
Result so far: 7874.0
Subtracting 3372 from 3938 leaves us with 566.
Fetch the next digit (5) from the dividend, attach it to 566 and continue: 5665 / 843

Going ahead to step 8:
If we divide 5665 by 843, we get 6 and a remainder of 607.
Use 6 as the next digit of our solution. 
Result so far: 78746.0
Subtract 5058 from 5665 to get 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Step 9:
When dividing 6070 by 843, we get 7 with a remainder of 169.
Write down 7 as next digit of the result. 
Result so far: 78746.7
Subtracting 5901 from 6070 leaves us with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Going ahead to step 10:
If we divide 1690 by 843, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 78746.72
Subtracting 1686 from 1690 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
843 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 78746.72
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
When dividing 400 by 843, we get 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 78746.72
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 78746.72 with a remainder of 0.004.
