66330346 ÷ 726 
We want to figure out the number of times 66330346 can be divided by 726.

Advancing to step 1:
If we divide 6 by 726, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 726

Moving on to step 2:
When dividing 66 by 726, we get 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 726

On to step 3:
726 can be fit into 663 0 times, resulting in a remainder of 663.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 663, we get 663.
Include the next digit (3) from the dividend after 663, then repeat: 6633 / 726

On to step 4:
6633 divided by 726 is 9 with a remainder of 99.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 6534 from 6633 leaves us with 99.
Fetch the next digit (0) from the dividend, attach it to 99 and continue: 990 / 726

Step 5:
If we divide 990 by 726, we get 1 and a remainder of 264.
Put 1 as the next digit of the answer. 
Result so far: 91.0
If we subtract 726 from 990, we get 264.
Fetch the next digit (3) from the dividend, attach it to 264 and continue: 2643 / 726

Advancing to step 6:
If we divide 2643 by 726, we get 3 and a remainder of 465.
The next digit of our result is 3. 
Result so far: 913.0
Subtract 2178 from 2643 to get 465.
Take the next digit (4) from the dividend and append it to 465, then repeat: 4654 / 726

Advancing to step 7:
If we divide 4654 by 726, we get 6 and a remainder of 298.
Write down 6 as next digit of the result. 
Result so far: 9136.0
The remainder is 298 after subtracting 4356 from 4654.
Append the next digit (6) from the dividend to 298 and continue with: 2986 / 726

Step 8:
726 goes into 2986 4 times with a remainder of 82.
The number 4 becomes the next digit in our result. 
Result so far: 91364.0
Subtract 2904 from 2986 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 9:
If we divide 820 by 726, we get 1 and a remainder of 94.
The next digit of our result is 1. 
Result so far: 91364.1
Deduct 726 from 820 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 10:
726 goes into 940 1 times with a remainder of 214.
Write down 1 as next digit of the result. 
Result so far: 91364.11
If we take 726 away from 940, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

The quotient of the division is 91364.11, and the remainder is 0.214.
