394656 ÷ 42 
Let's see how many times 42 fits into 394656.

Moving on to 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
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 42

Let's proceed to step 2:
39 divided by 42 is 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Include the next digit (4) from the dividend after 39, then repeat: 394 / 42

On to step 3:
The number 42 fits into 394 9 times, leaving a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 16 after subtracting 378 from 394.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 42

Step 4:
When dividing 166 by 42, we get 3 with a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 93.0
If we subtract 126 from 166, we get 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 42

Moving on to step 5:
405 divided by 42 is 9 with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 939.0
Subtracting 378 from 405 leaves us with 27.
Take the next digit (6) from the dividend and append it to 27, then repeat: 276 / 42

Step 6:
276 divided by 42 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 9396.0
If we take 252 away from 276, we end up 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.

On to step 7:
When dividing 240 by 42, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 9396.5
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
42 goes into 300 7 times with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 9396.57
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 9:
If we divide 60 by 42, we get 1 and a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 9396.571
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.

Step 10:
If we divide 180 by 42, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 9396.5714
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.

Going ahead to step 11:
When dividing 120 by 42, we get 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 9396.57142
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
When dividing 360 by 42, we get 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 9396.571428
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
240 divided by 42 is 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 9396.5714285
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
300 divided by 42 is 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 9396.57142857
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.

The final outcome is 9396.57142857, with a leftover of 6e-09.
