112021 divided by 42 
Our goal is to divide 112021 by 42.

Let's proceed to step 1:
When dividing 1 by 42, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 42

Moving on to step 2:
42 can be fit into 11 0 times, resulting in a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 42

Going ahead to step 3:
If we divide 112 by 42, we get 2 and a remainder of 28.
The next digit of our result is 2. 
Result so far: 2.0
If we take 84 away from 112, we end up with 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 42

Going ahead to step 4:
When dividing 280 by 42, we get 6 with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtracting 252 from 280 leaves us with 28.
Append the next digit (2) from the dividend to 28 and continue with: 282 / 42

Moving on to step 5:
42 goes into 282 6 times with a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 266.0
Subtracting 252 from 282 leaves us with 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 42

Going ahead to step 6:
301 divided by 42 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 2667.0
If we take 294 away from 301, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
If we divide 70 by 42, we get 1 and a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 2667.1
If we take 42 away from 70, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
42 can be fit into 280 6 times, resulting in a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 2667.16
Deduct 252 from 280 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
When dividing 280 by 42, we get 6 with a remainder of 28.
The next digit of our result is 6. 
Result so far: 2667.166
Subtract 252 from 280 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 2667.166 with a remainder of 0.0028.
