We look at the division of 298921 by 42 
Our goal is to divide 298921 by 42.

On to step 1:
2 divided by 42 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 42

Going ahead to step 2:
If we divide 29 by 42, we get 0 and a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 42

Moving on to step 3:
If we divide 298 by 42, we get 7 and a remainder of 4.
The next digit of our result is 7. 
Result so far: 7.0
If we take 294 away from 298, we end up with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 42

Advancing to step 4:
The number 42 fits into 49 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 71.0
The remainder is 7 after subtracting 42 from 49.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 42

Let's proceed to step 5:
The number 42 fits into 72 1 times, leaving a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 711.0
Subtracting 42 from 72 leaves us with 30.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 42

Let's proceed to step 6:
When dividing 301 by 42, we get 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 7117.0
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.

Step 7:
42 goes into 70 1 times with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 7117.1
Deduct 42 from 70 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.

Let's proceed to step 8:
The number 42 fits into 280 6 times, leaving a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 7117.16
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.

Let's proceed to step 9:
The number 42 fits into 280 6 times, leaving a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 7117.166
Subtracting 252 from 280 leaves us 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.

The final result is 7117.166 with a remainder of 0.0028.
