55512166 ÷ 323 
Our goal is to divide 55512166 by 323.

Step 1:
When dividing 5 by 323, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 323

On to step 2:
When dividing 55 by 323, we get 0 with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Bring next digit (5) of the dividend behind the 55 and repeat the process: 555 / 323

Step 3:
323 goes into 555 1 times with a remainder of 232.
The next digit of our result is 1. 
Result so far: 1.0
If we take 323 away from 555, we end up with 232.
Include the next digit (1) from the dividend after 232, then repeat: 2321 / 323

Let's proceed to step 4:
When dividing 2321 by 323, we get 7 with a remainder of 60.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtracting 2261 from 2321 leaves us with 60.
Grab the next digit (2) from the dividend, add it to 60, then carry on: 602 / 323

Advancing to step 5:
The number 323 fits into 602 1 times, leaving a remainder of 279.
Record the quotient 1 as the next digit in the result. 
Result so far: 171.0
The remainder is 279 after subtracting 323 from 602.
Take the next digit (1) from the dividend and append it to 279, then repeat: 2791 / 323

Going ahead to step 6:
2791 divided by 323 is 8 with a remainder of 207.
The number 8 becomes the next digit in our result. 
Result so far: 1718.0
If we subtract 2584 from 2791, we get 207.
Include the next digit (6) from the dividend after 207, then repeat: 2076 / 323

Step 7:
323 goes into 2076 6 times with a remainder of 138.
Write down 6 as next digit of the result. 
Result so far: 17186.0
If we take 1938 away from 2076, we end up with 138.
Grab the next digit (6) from the dividend, add it to 138, then carry on: 1386 / 323

Step 8:
When dividing 1386 by 323, we get 4 with a remainder of 94.
Put 4 as the next digit of the answer. 
Result so far: 171864.0
If we subtract 1292 from 1386, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 9:
323 can be fit into 940 2 times, resulting in a remainder of 294.
Use 2 as the next digit of our solution. 
Result so far: 171864.2
Subtracting 646 from 940 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Step 10:
If we divide 2940 by 323, we get 9 and a remainder of 33.
The next digit of our result is 9. 
Result so far: 171864.29
Subtracting 2907 from 2940 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 11:
323 goes into 330 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 171864.291
Deduct 323 from 330 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 12:
323 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 171864.291
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
The number 323 fits into 700 2 times, leaving a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 171864.29102
Subtract 646 from 700 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 14:
When dividing 540 by 323, we get 1 with a remainder of 217.
Use 1 as the next digit of our solution. 
Result so far: 171864.291021
The remainder is 217 after subtracting 323 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Going ahead to step 15:
When dividing 2170 by 323, we get 6 with a remainder of 232.
Record the quotient 6 as the next digit in the result. 
Result so far: 171864.2910216
The remainder is 232 after subtracting 1938 from 2170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 16:
2320 divided by 323 is 7 with a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 171864.29102167
If we subtract 2261 from 2320, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

After the division, we end up with 171864.29102167 and a remainder of 5.9e-08.
