We're dividing 55231789 by 300 
We're looking to find how many times 300 goes into 55231789.

Moving on to step 1:
300 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 300

Step 2:
300 can be fit into 55 0 times, resulting in 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 / 300

Step 3:
300 goes into 552 1 times with a remainder of 252.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 300 from 552, we get 252.
Bring next digit (3) of the dividend behind the 252 and repeat the process: 2523 / 300

Let's proceed to step 4:
300 goes into 2523 8 times with a remainder of 123.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 2400 from 2523 and we're left with 123.
Take the next digit (1) from the dividend and append it to 123, then repeat: 1231 / 300

Going ahead to step 5:
When dividing 1231 by 300, we get 4 with a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 184.0
Deduct 1200 from 1231 and we're left with 31.
Append the next digit (7) from the dividend to 31 and continue with: 317 / 300

On to step 6:
The number 300 fits into 317 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1841.0
Deduct 300 from 317 and we're left with 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 300

Advancing to step 7:
The number 300 fits into 178 0 times, leaving a remainder of 178.
Write down 0 as next digit of the result. 
Result so far: 18410.0
Subtract 0 from 178 to get 178.
Append the next digit (9) from the dividend to 178 and continue with: 1789 / 300

Moving on to step 8:
When dividing 1789 by 300, we get 5 with a remainder of 289.
Record the quotient 5 as the next digit in the result. 
Result so far: 184105.0
If we take 1500 away from 1789, we end up with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Advancing to step 9:
2890 divided by 300 is 9 with a remainder of 190.
The next digit of our result is 9. 
Result so far: 184105.9
The remainder is 190 after subtracting 2700 from 2890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 10:
If we divide 1900 by 300, we get 6 and a remainder of 100.
Write down 6 as next digit of the result. 
Result so far: 184105.96
If we take 1800 away from 1900, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
The number 300 fits into 1000 3 times, leaving a remainder of 100.
Put 3 as the next digit of the answer. 
Result so far: 184105.963
If we take 900 away from 1000, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 12:
If we divide 1000 by 300, we get 3 and a remainder of 100.
Write down 3 as next digit of the result. 
Result so far: 184105.9633
Deduct 900 from 1000 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 184105.9633 with a remainder of 0.001.
