155098 ÷ 90 
We want to figure out the number of times 155098 can be divided by 90.

Let's proceed to step 1:
When dividing 1 by 90, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 90

Let's proceed to step 2:
If we divide 15 by 90, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 90

Moving on to step 3:
When dividing 155 by 90, we get 1 with a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 90 from 155, we get 65.
Include the next digit (0) from the dividend after 65, then repeat: 650 / 90

Going ahead to step 4:
When dividing 650 by 90, we get 7 with a remainder of 20.
The next digit of our result is 7. 
Result so far: 17.0
If we subtract 630 from 650, we get 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 90

Advancing to step 5:
90 goes into 209 2 times with a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 172.0
If we subtract 180 from 209, we get 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 90

Step 6:
90 goes into 298 3 times with a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 1723.0
The remainder is 28 after subtracting 270 from 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 7:
If we divide 280 by 90, we get 3 and a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 1723.3
If we subtract 270 from 280, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
If we divide 100 by 90, we get 1 and a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1723.31
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
90 goes into 100 1 times with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1723.311
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 1723.311, with a leftover of 0.001.
