We're dividing 221335 by 42 
We want to figure out the number of times 221335 can be divided by 42.

Step 1:
2 divided by 42 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 42

Going ahead to step 2:
The number 42 fits into 22 0 times, leaving a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 42

On to step 3:
42 goes into 221 5 times with a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 210 from 221 to get 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 42

Step 4:
The number 42 fits into 113 2 times, leaving a remainder of 29.
Write down 2 as next digit of the result. 
Result so far: 52.0
Subtracting 84 from 113 leaves us with 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 42

Let's proceed to step 5:
When dividing 293 by 42, we get 6 with a remainder of 41.
The number 6 becomes the next digit in our result. 
Result so far: 526.0
The remainder is 41 after subtracting 252 from 293.
Bring next digit (5) of the dividend behind the 41 and repeat the process: 415 / 42

On to step 6:
The number 42 fits into 415 9 times, leaving a remainder of 37.
The next digit of our result is 9. 
Result so far: 5269.0
Subtracting 378 from 415 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.

Let's proceed to step 7:
The number 42 fits into 370 8 times, leaving a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 5269.8
Deduct 336 from 370 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
When dividing 340 by 42, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 5269.88
If we subtract 336 from 340, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 5269.88 with a remaining 0.004.
