We look at the division of 294721 by 42 
We want to figure out the number of times 294721 can be divided by 42.

Let's proceed to 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
The remainder is 2 after subtracting 0 from 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 42

Moving on to step 2:
The number 42 fits into 29 0 times, leaving a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Fetch the next digit (4) from the dividend, attach it to 29 and continue: 294 / 42

On to step 3:
42 can be fit into 294 7 times, resulting in a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 294 away from 294, we end up with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 42

On to step 4:
7 divided by 42 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
If we take 0 away from 7, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 42

Let's proceed to step 5:
If we divide 72 by 42, we get 1 and a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 701.0
If we subtract 42 from 72, we get 30.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 42

Advancing to step 6:
If we divide 301 by 42, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 7017.0
Subtracting 294 from 301 leaves us 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:
70 divided by 42 is 1 with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 7017.1
Subtracting 42 from 70 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.

On to step 8:
When dividing 280 by 42, we get 6 with a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 7017.16
If we take 252 away from 280, 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.

On to step 9:
When dividing 280 by 42, we get 6 with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 7017.166
If we subtract 252 from 280, we 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 quotient of the division is 7017.166, and the remainder is 0.0028.
