We divide 305220 by 42
Our goal is to divide 305220 by 42.

Advancing to step 1:
42 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 42

Going ahead to step 2:
When dividing 30 by 42, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 42

Step 3:
305 divided by 42 is 7 with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 294 from 305 and we're left with 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 42

Step 4:
112 divided by 42 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
The remainder is 28 after subtracting 84 from 112.
Include the next digit (2) from the dividend after 28, then repeat: 282 / 42

Let's proceed to step 5:
42 goes into 282 6 times with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 726.0
If we take 252 away from 282, we end up with 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 42

Going ahead to step 6:
If we divide 300 by 42, we get 7 and a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 7267.0
If we subtract 294 from 300, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
42 goes into 60 1 times with a remainder of 18.
The next digit of our result is 1. 
Result so far: 7267.1
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
42 goes into 180 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 7267.14
If we subtract 168 from 180, we get 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 9:
42 goes into 120 2 times with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 7267.142
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.

Step 10:
When dividing 360 by 42, we get 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 7267.1428
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.

Going ahead to step 11:
The number 42 fits into 240 5 times, leaving a remainder of 30.
The next digit of our result is 5. 
Result so far: 7267.14285
Subtract 210 from 240 to 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.

Going ahead to step 12:
42 goes into 300 7 times with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 7267.142857
Subtracting 294 from 300 leaves us 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.

On to step 13:
When dividing 60 by 42, we get 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 7267.1428571
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
180 divided by 42 is 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 7267.14285714
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 7267.14285714, with a leftover of 1.2e-08.
