We're dividing 18040221 by 223 
We want to divide 18040221 by 223.

Moving on to step 1:
223 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 223

Step 2:
18 divided by 223 is 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 223

Going ahead to step 3:
If we divide 180 by 223, we get 0 and a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 180 after subtracting 0 from 180.
Fetch the next digit (4) from the dividend, attach it to 180 and continue: 1804 / 223

Step 4:
If we divide 1804 by 223, we get 8 and a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 1784 from 1804 leaves us with 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 223

Step 5:
200 divided by 223 is 0 with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
The remainder is 200 after subtracting 0 from 200.
Append the next digit (2) from the dividend to 200 and continue with: 2002 / 223

On to step 6:
When dividing 2002 by 223, we get 8 with a remainder of 218.
Use 8 as the next digit of our solution. 
Result so far: 808.0
Subtracting 1784 from 2002 leaves us with 218.
Fetch the next digit (2) from the dividend, attach it to 218 and continue: 2182 / 223

On to step 7:
If we divide 2182 by 223, we get 9 and a remainder of 175.
Record the quotient 9 as the next digit in the result. 
Result so far: 8089.0
Deduct 2007 from 2182 and we're left with 175.
Append the next digit (1) from the dividend to 175 and continue with: 1751 / 223

Step 8:
The number 223 fits into 1751 7 times, leaving a remainder of 190.
The next digit of our result is 7. 
Result so far: 80897.0
Subtract 1561 from 1751 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 9:
223 goes into 1900 8 times with a remainder of 116.
Write down 8 as next digit of the result. 
Result so far: 80897.8
If we subtract 1784 from 1900, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 10:
When dividing 1160 by 223, we get 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 80897.85
If we take 1115 away from 1160, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 11:
450 divided by 223 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 80897.852
Subtracting 446 from 450 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
40 divided by 223 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 80897.852
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
The number 223 fits into 400 1 times, leaving a remainder of 177.
Write down 1 as next digit of the result. 
Result so far: 80897.85201
The remainder is 177 after subtracting 223 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Advancing to step 14:
223 can be fit into 1770 7 times, resulting in a remainder of 209.
Record the quotient 7 as the next digit in the result. 
Result so far: 80897.852017
If we take 1561 away from 1770, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Advancing to step 15:
223 goes into 2090 9 times with a remainder of 83.
The number 9 becomes the next digit in our result. 
Result so far: 80897.8520179
The remainder is 83 after subtracting 2007 from 2090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 16:
223 can be fit into 830 3 times, resulting in a remainder of 161.
Put 3 as the next digit of the answer. 
Result so far: 80897.85201793
If we take 669 away from 830, we end up with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

The final outcome is 80897.85201793, with a leftover of 1.61e-07.
