We look at the division of 305237 by 42 
We're looking to find how many times 42 goes into 305237.

Going ahead to step 1:
When dividing 3 by 42, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 42

Moving on to step 2:
42 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 42

Advancing to step 3:
305 divided by 42 is 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 294 from 305, we get 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 42

Step 4:
The number 42 fits into 112 2 times, leaving a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 72.0
If we take 84 away from 112, we end up with 28.
Fetch the next digit (3) from the dividend, attach it to 28 and continue: 283 / 42

Advancing to step 5:
The number 42 fits into 283 6 times, leaving a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 726.0
Deduct 252 from 283 and we're left with 31.
Grab the next digit (7) from the dividend, add it to 31, then carry on: 317 / 42

Advancing to step 6:
317 divided by 42 is 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 7267.0
Deduct 294 from 317 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
If we divide 230 by 42, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 7267.5
Subtracting 210 from 230 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
42 goes into 200 4 times with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 7267.54
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
42 can be fit into 320 7 times, resulting in a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 7267.547
Subtracting 294 from 320 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
The number 42 fits into 260 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 7267.5476
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
If we divide 80 by 42, we get 1 and a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 7267.54761
If we take 42 away from 80, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
42 goes into 380 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 7267.547619
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
42 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 7267.547619
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
42 can be fit into 200 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 7267.54761904
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 7267.54761904, and the remainder is 3.2e-08.
