We look at the division of 55204700 by 321 
We're looking to find how many times 321 goes into 55204700.

On to step 1:
When dividing 5 by 321, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 321

On to step 2:
The number 321 fits into 55 0 times, leaving a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Bring next digit (2) of the dividend behind the 55 and repeat the process: 552 / 321

Advancing to step 3:
The number 321 fits into 552 1 times, leaving a remainder of 231.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 321 away from 552, we end up with 231.
Include the next digit (0) from the dividend after 231, then repeat: 2310 / 321

Let's proceed to step 4:
If we divide 2310 by 321, we get 7 and a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 2247 from 2310 to get 63.
Append the next digit (4) from the dividend to 63 and continue with: 634 / 321

Going ahead to step 5:
If we divide 634 by 321, we get 1 and a remainder of 313.
Record the quotient 1 as the next digit in the result. 
Result so far: 171.0
Deduct 321 from 634 and we're left with 313.
Bring next digit (7) of the dividend behind the 313 and repeat the process: 3137 / 321

Advancing to step 6:
When dividing 3137 by 321, we get 9 with a remainder of 248.
Use 9 as the next digit of our solution. 
Result so far: 1719.0
If we subtract 2889 from 3137, we get 248.
Grab the next digit (0) from the dividend, add it to 248, then carry on: 2480 / 321

On to step 7:
When dividing 2480 by 321, we get 7 with a remainder of 233.
Write down 7 as next digit of the result. 
Result so far: 17197.0
If we take 2247 away from 2480, we end up with 233.
Fetch the next digit (0) from the dividend, attach it to 233 and continue: 2330 / 321

Advancing to step 8:
The number 321 fits into 2330 7 times, leaving a remainder of 83.
Record the quotient 7 as the next digit in the result. 
Result so far: 171977.0
Deduct 2247 from 2330 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 9:
321 can be fit into 830 2 times, resulting in a remainder of 188.
The next digit of our result is 2. 
Result so far: 171977.2
If we subtract 642 from 830, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 10:
1880 divided by 321 is 5 with a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 171977.25
If we take 1605 away from 1880, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 11:
321 goes into 2750 8 times with a remainder of 182.
Record the quotient 8 as the next digit in the result. 
Result so far: 171977.258
Subtract 2568 from 2750 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 12:
If we divide 1820 by 321, we get 5 and a remainder of 215.
Write down 5 as next digit of the result. 
Result so far: 171977.2585
Subtract 1605 from 1820 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 13:
When dividing 2150 by 321, we get 6 with a remainder of 224.
Record the quotient 6 as the next digit in the result. 
Result so far: 171977.25856
The remainder is 224 after subtracting 1926 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 14:
The number 321 fits into 2240 6 times, leaving a remainder of 314.
Record the quotient 6 as the next digit in the result. 
Result so far: 171977.258566
Deduct 1926 from 2240 and we're left with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Our division results in 171977.258566 with a remaining 3.14e-05.
