310023 divided by 42 
Let's see how many times 42 fits into 310023.

Moving on to step 1:
42 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 42

Step 2:
42 goes into 31 0 times with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 42

Let's proceed to step 3:
When dividing 310 by 42, we get 7 with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 294 away from 310, we end up with 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 42

Going ahead to step 4:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
Subtracting 126 from 160 leaves us with 34.
Grab the next digit (2) from the dividend, add it to 34, then carry on: 342 / 42

Step 5:
When dividing 342 by 42, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 738.0
The remainder is 6 after subtracting 336 from 342.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 42

Step 6:
63 divided by 42 is 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 7381.0
Deduct 42 from 63 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
42 goes into 210 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 7381.5
Subtract 210 from 210 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
42 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7381.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
If we divide 0 by 42, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7381.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 7381.5 with a remainder of 0.0.
