392437 ÷ 42 
We want to figure out the number of times 392437 can be divided by 42.

Moving on to step 1:
3 divided by 42 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 42

Step 2:
42 can be fit into 39 0 times, resulting in a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Include the next digit (2) from the dividend after 39, then repeat: 392 / 42

Advancing to step 3:
42 can be fit into 392 9 times, resulting in a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 378 from 392 and we're left with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 42

Going ahead to step 4:
The number 42 fits into 144 3 times, leaving a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 93.0
Subtracting 126 from 144 leaves us with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 42

Going ahead to step 5:
When dividing 183 by 42, we get 4 with a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 934.0
Subtract 168 from 183 to get 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 42

Going ahead to step 6:
If we divide 157 by 42, we get 3 and a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 9343.0
If we subtract 126 from 157, 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.

Advancing to step 7:
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: 9343.7
The remainder is 16 after subtracting 294 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
160 divided by 42 is 3 with a remainder of 34.
The next digit of our result is 3. 
Result so far: 9343.73
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.

Moving on to step 9:
When dividing 340 by 42, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 9343.738
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
40 divided by 42 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 9343.738
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
The number 42 fits into 400 9 times, leaving a remainder of 22.
The next digit of our result is 9. 
Result so far: 9343.73809
Deduct 378 from 400 and we're left 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.

Going ahead to step 12:
The number 42 fits into 220 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 9343.738095
Subtracting 210 from 220 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 9343.7380952
Subtracting 84 from 100 leaves us 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:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 9343.73809523
Subtract 126 from 160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The quotient of the division is 9343.73809523, and the remainder is 3.4e-08.
