305940 ÷ 42 
Let's see how many times 42 fits into 305940.

On to step 1:
42 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 42

Let's proceed to step 2:
42 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Fetch the next digit (5) from the dividend, attach it to 30 and continue: 305 / 42

Advancing to step 3:
42 goes into 305 7 times 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.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 42

Advancing to step 4:
42 can be fit into 119 2 times, resulting in a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Deduct 84 from 119 and we're left with 35.
Append the next digit (4) from the dividend to 35 and continue with: 354 / 42

Advancing to step 5:
354 divided by 42 is 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 728.0
If we subtract 336 from 354, we get 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 42

Advancing to step 6:
If we divide 180 by 42, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 7284.0
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.

Advancing to step 7:
42 goes into 120 2 times with a remainder of 36.
The next digit of our result is 2. 
Result so far: 7284.2
Deduct 84 from 120 and we're left 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 8:
When dividing 360 by 42, we get 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 7284.28
The remainder is 24 after subtracting 336 from 360.
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 9:
240 divided by 42 is 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 7284.285
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.

Moving on to step 10:
When dividing 300 by 42, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 7284.2857
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.

Moving on to step 11:
60 divided by 42 is 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 7284.28571
If we subtract 42 from 60, we 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.

Let's proceed to step 12:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 7284.285714
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.

Moving on to step 13:
120 divided by 42 is 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 7284.2857142
Deduct 84 from 120 and we're left 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 14:
360 divided by 42 is 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 7284.28571428
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 final outcome is 7284.28571428, with a leftover of 2.4e-08.
