66723272 ÷ 311 
We want to figure out the number of times 66723272 can be divided by 311.

On to step 1:
6 divided by 311 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 311

On to step 2:
The number 311 fits into 66 0 times, leaving a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Take the next digit (7) from the dividend and append it to 66, then repeat: 667 / 311

On to step 3:
The number 311 fits into 667 2 times, leaving a remainder of 45.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 622 away from 667, we end up with 45.
Append the next digit (2) from the dividend to 45 and continue with: 452 / 311

On to step 4:
When dividing 452 by 311, we get 1 with a remainder of 141.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 311 from 452, we get 141.
Append the next digit (3) from the dividend to 141 and continue with: 1413 / 311

Step 5:
311 can be fit into 1413 4 times, resulting in a remainder of 169.
The next digit of our result is 4. 
Result so far: 214.0
Deduct 1244 from 1413 and we're left with 169.
Bring next digit (2) of the dividend behind the 169 and repeat the process: 1692 / 311

Let's proceed to step 6:
311 goes into 1692 5 times with a remainder of 137.
The next digit of our result is 5. 
Result so far: 2145.0
Subtracting 1555 from 1692 leaves us with 137.
Take the next digit (7) from the dividend and append it to 137, then repeat: 1377 / 311

On to step 7:
When dividing 1377 by 311, we get 4 with a remainder of 133.
Use 4 as the next digit of our solution. 
Result so far: 21454.0
If we take 1244 away from 1377, we end up with 133.
Bring next digit (2) of the dividend behind the 133 and repeat the process: 1332 / 311

Step 8:
1332 divided by 311 is 4 with a remainder of 88.
Use 4 as the next digit of our solution. 
Result so far: 214544.0
Subtracting 1244 from 1332 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 9:
311 can be fit into 880 2 times, resulting in a remainder of 258.
Write down 2 as next digit of the result. 
Result so far: 214544.2
If we subtract 622 from 880, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Step 10:
2580 divided by 311 is 8 with a remainder of 92.
Put 8 as the next digit of the answer. 
Result so far: 214544.28
The remainder is 92 after subtracting 2488 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 11:
If we divide 920 by 311, we get 2 and a remainder of 298.
Write down 2 as next digit of the result. 
Result so far: 214544.282
Subtracting 622 from 920 leaves us with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 12:
2980 divided by 311 is 9 with a remainder of 181.
Record the quotient 9 as the next digit in the result. 
Result so far: 214544.2829
The remainder is 181 after subtracting 2799 from 2980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Let's proceed to step 13:
If we divide 1810 by 311, we get 5 and a remainder of 255.
Write down 5 as next digit of the result. 
Result so far: 214544.28295
The remainder is 255 after subtracting 1555 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Advancing to step 14:
311 goes into 2550 8 times with a remainder of 62.
The next digit of our result is 8. 
Result so far: 214544.282958
The remainder is 62 after subtracting 2488 from 2550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 15:
When dividing 620 by 311, we get 1 with a remainder of 309.
Use 1 as the next digit of our solution. 
Result so far: 214544.2829581
Subtract 311 from 620 to get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Advancing to step 16:
3090 divided by 311 is 9 with a remainder of 291.
The number 9 becomes the next digit in our result. 
Result so far: 214544.28295819
Subtract 2799 from 3090 to get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

The final result is 214544.28295819 with a remainder of 2.91e-07.
