We look at the division of 55212439 by 306 
We want to figure out the number of times 55212439 can be divided by 306.

Step 1:
306 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 306

Going ahead to step 2:
55 divided by 306 is 0 with a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Grab the next digit (2) from the dividend, add it to 55, then carry on: 552 / 306

Let's proceed to step 3:
306 goes into 552 1 times with a remainder of 246.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 306 away from 552, we end up with 246.
Include the next digit (1) from the dividend after 246, then repeat: 2461 / 306

Step 4:
When dividing 2461 by 306, we get 8 with a remainder of 13.
The next digit of our result is 8. 
Result so far: 18.0
If we take 2448 away from 2461, we end up with 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 306

Advancing to step 5:
If we divide 132 by 306, we get 0 and a remainder of 132.
The number 0 becomes the next digit in our result. 
Result so far: 180.0
The remainder is 132 after subtracting 0 from 132.
Include the next digit (4) from the dividend after 132, then repeat: 1324 / 306

Moving on to step 6:
If we divide 1324 by 306, we get 4 and a remainder of 100.
The next digit of our result is 4. 
Result so far: 1804.0
Subtracting 1224 from 1324 leaves us with 100.
Fetch the next digit (3) from the dividend, attach it to 100 and continue: 1003 / 306

On to step 7:
The number 306 fits into 1003 3 times, leaving a remainder of 85.
The next digit of our result is 3. 
Result so far: 18043.0
Deduct 918 from 1003 and we're left with 85.
Fetch the next digit (9) from the dividend, attach it to 85 and continue: 859 / 306

Let's proceed to step 8:
306 can be fit into 859 2 times, resulting in a remainder of 247.
Use 2 as the next digit of our solution. 
Result so far: 180432.0
If we subtract 612 from 859, we get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

On to step 9:
If we divide 2470 by 306, we get 8 and a remainder of 22.
The next digit of our result is 8. 
Result so far: 180432.8
Subtracting 2448 from 2470 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
306 goes into 220 0 times with a remainder of 220.
The next digit of our result is 0. 
Result so far: 180432.8
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 11:
The number 306 fits into 2200 7 times, leaving a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 180432.807
If we take 2142 away from 2200, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 12:
The number 306 fits into 580 1 times, leaving a remainder of 274.
The next digit of our result is 1. 
Result so far: 180432.8071
If we take 306 away from 580, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Moving on to step 13:
306 can be fit into 2740 8 times, resulting in a remainder of 292.
Write down 8 as next digit of the result. 
Result so far: 180432.80718
If we take 2448 away from 2740, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 14:
If we divide 2920 by 306, we get 9 and a remainder of 166.
The next digit of our result is 9. 
Result so far: 180432.807189
Subtracting 2754 from 2920 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 15:
The number 306 fits into 1660 5 times, leaving a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 180432.8071895
Deduct 1530 from 1660 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 16:
When dividing 1300 by 306, we get 4 with a remainder of 76.
The next digit of our result is 4. 
Result so far: 180432.80718954
Deduct 1224 from 1300 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 180432.80718954 with a remainder of 7.6e-08.
