305035 divided by 42 
Let's see how many times 42 fits into 305035.

Step 1:
If we divide 3 by 42, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in 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:
42 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 42

Let's proceed to step 3:
42 can be fit into 305 7 times, resulting in a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 11 after subtracting 294 from 305.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 42

Going ahead to step 4:
42 goes into 110 2 times with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 72.0
The remainder is 26 after subtracting 84 from 110.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 42

Moving on to step 5:
The number 42 fits into 263 6 times, leaving a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 726.0
Deduct 252 from 263 and we're left with 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 42

Going ahead to step 6:
When dividing 115 by 42, we get 2 with a remainder of 31.
Write down 2 as next digit of the result. 
Result so far: 7262.0
If we subtract 84 from 115, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 7:
42 goes into 310 7 times with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 7262.7
If we subtract 294 from 310, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
If we divide 160 by 42, we get 3 and a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 7262.73
Subtracting 126 from 160 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
42 can be fit into 340 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 7262.738
If we take 336 away from 340, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
42 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 7262.738
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
42 can be fit into 400 9 times, resulting in a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 7262.73809
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 12:
220 divided by 42 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 7262.738095
If we subtract 210 from 220, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 7262.7380952
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
If we divide 160 by 42, we get 3 and a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 7262.73809523
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 7262.73809523 with a remainder of 3.4e-08.
