Let's divide 550361 by 90
We want to divide 550361 by 90.

Going ahead to step 1:
5 divided by 90 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 90

Advancing to step 2:
55 divided by 90 is 0 with a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Include the next digit (0) from the dividend after 55, then repeat: 550 / 90

Moving on to step 3:
The number 90 fits into 550 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 540 away from 550, we end up with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 90

Moving on to step 4:
90 goes into 103 1 times with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 61.0
The remainder is 13 after subtracting 90 from 103.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 90

Moving on to step 5:
The number 90 fits into 136 1 times, leaving a remainder of 46.
The next digit of our result is 1. 
Result so far: 611.0
If we take 90 away from 136, we end up with 46.
Append the next digit (1) from the dividend to 46 and continue with: 461 / 90

On to step 6:
90 goes into 461 5 times with a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 6115.0
Subtracting 450 from 461 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
90 goes into 110 1 times with a remainder of 20.
The next digit of our result is 1. 
Result so far: 6115.1
If we subtract 90 from 110, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
If we divide 200 by 90, we get 2 and a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 6115.12
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
90 can be fit into 200 2 times, resulting in a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 6115.122
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 6115.122 and a remainder of 0.002.
