555158 ÷ 90 
Let's see how many times 90 fits into 555158.

Moving on to step 1:
90 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 90

Going ahead to step 2:
55 divided by 90 is 0 with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Grab the next digit (5) from the dividend, add it to 55, then carry on: 555 / 90

Step 3:
555 divided by 90 is 6 with a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 540 from 555, we get 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 90

Step 4:
90 goes into 151 1 times with a remainder of 61.
The next digit of our result is 1. 
Result so far: 61.0
If we subtract 90 from 151, we get 61.
Append the next digit (5) from the dividend to 61 and continue with: 615 / 90

Let's proceed to step 5:
When dividing 615 by 90, we get 6 with a remainder of 75.
Use 6 as the next digit of our solution. 
Result so far: 616.0
Subtract 540 from 615 to get 75.
Grab the next digit (8) from the dividend, add it to 75, then carry on: 758 / 90

Let's proceed to step 6:
If we divide 758 by 90, we get 8 and a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 6168.0
Subtract 720 from 758 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
The number 90 fits into 380 4 times, leaving a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 6168.4
Subtracting 360 from 380 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.

Moving on to step 8:
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: 6168.42
If we take 180 away from 200, 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.

Moving on to step 9:
90 goes into 200 2 times with a remainder of 20.
The next digit of our result is 2. 
Result so far: 6168.422
If we take 180 away from 200, 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.

Our division results in 6168.422 with a remaining 0.002.
