We divide 285390 by 55
We're looking to find how many times 55 goes into 285390.

Going ahead to step 1:
The number 55 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 55

Going ahead to step 2:
The number 55 fits into 28 0 times, leaving a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 55

Going ahead to step 3:
55 goes into 285 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 10 after subtracting 275 from 285.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 55

Let's proceed to step 4:
103 divided by 55 is 1 with a remainder of 48.
The next digit of our result is 1. 
Result so far: 51.0
Subtracting 55 from 103 leaves us with 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 55

On to step 5:
If we divide 489 by 55, we get 8 and a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 518.0
Subtract 440 from 489 to get 49.
Append the next digit (0) from the dividend to 49 and continue with: 490 / 55

On to step 6:
The number 55 fits into 490 8 times, leaving a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 5188.0
If we subtract 440 from 490, we 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.

On to step 7:
55 can be fit into 500 9 times, resulting in a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 5188.9
If we take 495 away from 500, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
When dividing 50 by 55, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 5188.9
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 9:
When dividing 500 by 55, we get 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 5188.909
Subtracting 495 from 500 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
When dividing 50 by 55, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 5188.909
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.

Going ahead to step 11:
55 can be fit into 500 9 times, resulting in a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 5188.90909
The remainder is 5 after subtracting 495 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
55 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 5188.90909
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
500 divided by 55 is 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 5188.9090909
If we subtract 495 from 500, we 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.

Advancing to step 14:
The number 55 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 5188.9090909
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 5188.9090909 with a balance of 5e-08.
