We look at the division of 221109 by 42 
Let's see how many times 42 fits into 221109.

On to step 1:
If we divide 2 by 42, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 42

Step 2:
42 goes into 22 0 times with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 42

Let's proceed to step 3:
221 divided by 42 is 5 with a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 11 after subtracting 210 from 221.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 42

Moving on to step 4:
When dividing 111 by 42, we get 2 with a remainder of 27.
The next digit of our result is 2. 
Result so far: 52.0
If we take 84 away from 111, we end up with 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 42

Step 5:
42 goes into 270 6 times with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 526.0
The remainder is 18 after subtracting 252 from 270.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 42

Step 6:
189 divided by 42 is 4 with a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 5264.0
If we take 168 away from 189, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
If we divide 210 by 42, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5264.5
Subtract 210 from 210 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
42 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5264.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
The number 42 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5264.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 5264.5, with a leftover of 0.0.
