We're dividing 15223 by 98 
We want to divide 15223 by 98.

On to step 1:
The number 98 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 98

Let's proceed to step 2:
If we divide 15 by 98, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 98

Moving on to step 3:
98 can be fit into 152 1 times, resulting in a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 98 from 152 to get 54.
Append the next digit (2) from the dividend to 54 and continue with: 542 / 98

Going ahead to step 4:
542 divided by 98 is 5 with a remainder of 52.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 490 from 542, we get 52.
Append the next digit (3) from the dividend to 52 and continue with: 523 / 98

Step 5:
98 can be fit into 523 5 times, resulting in a remainder of 33.
Put 5 as the next digit of the answer. 
Result so far: 155.0
Subtracting 490 from 523 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 6:
330 divided by 98 is 3 with a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 155.3
Deduct 294 from 330 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
98 goes into 360 3 times with a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 155.33
Subtracting 294 from 360 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final result is 155.33 with a remainder of 0.066.
