55163 divided by 90 
We want to figure out the number of times 55163 can be divided by 90.

Going ahead to step 1:
The number 90 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 90

Advancing to step 2:
When dividing 55 by 90, we get 0 with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Append the next digit (1) from the dividend to 55 and continue with: 551 / 90

Let's proceed to step 3:
90 goes into 551 6 times with a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 540 from 551 to get 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 90

On to step 4:
90 goes into 116 1 times with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
The remainder is 26 after subtracting 90 from 116.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 90

Let's proceed to step 5:
The number 90 fits into 263 2 times, leaving a remainder of 83.
The next digit of our result is 2. 
Result so far: 612.0
If we subtract 180 from 263, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 6:
90 can be fit into 830 9 times, resulting in a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 612.9
If we take 810 away from 830, we end up 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.

On to step 7:
The number 90 fits into 200 2 times, leaving a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 612.92
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
The number 90 fits into 200 2 times, leaving a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 612.922
Deduct 180 from 200 and we're left 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.

The final result is 612.922 with a remainder of 0.002.
