55439459 divided by 321 
We're looking to find how many times 321 goes into 55439459.

Let's proceed to step 1:
321 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 321

Let's proceed to step 2:
When dividing 55 by 321, we get 0 with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Grab the next digit (4) from the dividend, add it to 55, then carry on: 554 / 321

Moving on to step 3:
321 goes into 554 1 times with a remainder of 233.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 233 after subtracting 321 from 554.
Include the next digit (3) from the dividend after 233, then repeat: 2333 / 321

Going ahead to step 4:
321 goes into 2333 7 times with a remainder of 86.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 2247 away from 2333, we end up with 86.
Take the next digit (9) from the dividend and append it to 86, then repeat: 869 / 321

Going ahead to step 5:
If we divide 869 by 321, we get 2 and a remainder of 227.
Record the quotient 2 as the next digit in the result. 
Result so far: 172.0
Subtracting 642 from 869 leaves us with 227.
Bring next digit (4) of the dividend behind the 227 and repeat the process: 2274 / 321

Let's proceed to step 6:
321 can be fit into 2274 7 times, resulting in a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 1727.0
Subtracting 2247 from 2274 leaves us with 27.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 321

Step 7:
The number 321 fits into 275 0 times, leaving a remainder of 275.
The next digit of our result is 0. 
Result so far: 17270.0
Subtract 0 from 275 to get 275.
Include the next digit (9) from the dividend after 275, then repeat: 2759 / 321

Moving on to step 8:
2759 divided by 321 is 8 with a remainder of 191.
The number 8 becomes the next digit in our result. 
Result so far: 172708.0
Subtracting 2568 from 2759 leaves us with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

On to step 9:
The number 321 fits into 1910 5 times, leaving a remainder of 305.
Write down 5 as next digit of the result. 
Result so far: 172708.5
The remainder is 305 after subtracting 1605 from 1910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 10:
321 goes into 3050 9 times with a remainder of 161.
Use 9 as the next digit of our solution. 
Result so far: 172708.59
Subtract 2889 from 3050 to get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Step 11:
1610 divided by 321 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 172708.595
Subtract 1605 from 1610 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
If we divide 50 by 321, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 172708.595
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 13:
321 can be fit into 500 1 times, resulting in a remainder of 179.
Write down 1 as next digit of the result. 
Result so far: 172708.59501
Subtracting 321 from 500 leaves us with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

On to step 14:
321 can be fit into 1790 5 times, resulting in a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 172708.595015
Subtracting 1605 from 1790 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 15:
If we divide 1850 by 321, we get 5 and a remainder of 245.
Put 5 as the next digit of the answer. 
Result so far: 172708.5950155
Subtract 1605 from 1850 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

The final result is 172708.5950155 with a remainder of 2.45e-06.
