223867 ÷ 90 
Our goal is to divide 223867 by 90.

Let's proceed to step 1:
The number 90 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 90

On to step 2:
The number 90 fits into 22 0 times, leaving a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Append the next digit (3) from the dividend to 22 and continue with: 223 / 90

Step 3:
When dividing 223 by 90, we get 2 with a remainder of 43.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 180 from 223 and we're left with 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 90

On to step 4:
The number 90 fits into 438 4 times, leaving a remainder of 78.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtracting 360 from 438 leaves us with 78.
Take the next digit (6) from the dividend and append it to 78, then repeat: 786 / 90

Going ahead to step 5:
When dividing 786 by 90, we get 8 with a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 248.0
If we take 720 away from 786, we end up with 66.
Include the next digit (7) from the dividend after 66, then repeat: 667 / 90

Going ahead to step 6:
If we divide 667 by 90, we get 7 and a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 2487.0
Subtracting 630 from 667 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
90 goes into 370 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 2487.4
If we subtract 360 from 370, 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.

Going ahead to step 8:
90 can be fit into 100 1 times, resulting in a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 2487.41
If we subtract 90 from 100, 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.

Advancing to step 9:
If we divide 100 by 90, we get 1 and a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 2487.411
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 2487.411 with a remaining 0.001.
