303042 divided by 42 
Our goal is to divide 303042 by 42.

Going ahead to step 1:
42 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 42

Advancing to step 2:
If we divide 30 by 42, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 42

Advancing to step 3:
42 can be fit into 303 7 times, resulting in a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 294 from 303 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 42

On to step 4:
When dividing 90 by 42, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 72.0
Deduct 84 from 90 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 42

Moving on to step 5:
The number 42 fits into 64 1 times, leaving a remainder of 22.
The next digit of our result is 1. 
Result so far: 721.0
If we take 42 away from 64, we end up with 22.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 42

Moving on to step 6:
When dividing 222 by 42, we get 5 with a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 7215.0
If we take 210 away from 222, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
120 divided by 42 is 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 7215.2
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
If we divide 360 by 42, we get 8 and a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 7215.28
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
If we divide 240 by 42, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 7215.285
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
300 divided by 42 is 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 7215.2857
Deduct 294 from 300 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 7215.28571
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 12:
180 divided by 42 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 7215.285714
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
120 divided by 42 is 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 7215.2857142
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 14:
360 divided by 42 is 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 7215.28571428
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 7215.28571428, and the remainder is 2.4e-08.
