392790 ÷ 42 
Let's see how many times 42 fits into 392790.

Let's proceed to step 1:
42 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
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
If we subtract 0 from 39, we get 39.
Fetch the next digit (2) from the dividend, attach it to 39 and continue: 392 / 42

Advancing to step 3:
392 divided by 42 is 9 with a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 378 from 392 to get 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 42

Step 4:
42 can be fit into 147 3 times, resulting in a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
The remainder is 21 after subtracting 126 from 147.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 42

Going ahead to step 5:
42 goes into 219 5 times with a remainder of 9.
The next digit of our result is 5. 
Result so far: 935.0
If we subtract 210 from 219, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 42

Let's proceed to step 6:
The number 42 fits into 90 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 9352.0
If we subtract 84 from 90, 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 7:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 9352.1
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 9352.14
If we subtract 168 from 180, we 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 9:
42 can be fit into 120 2 times, resulting in a remainder of 36.
The next digit of our result is 2. 
Result so far: 9352.142
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.

On to step 10:
If we divide 360 by 42, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 9352.1428
Deduct 336 from 360 and we're left 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.

Let's proceed to step 11:
240 divided by 42 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 9352.14285
Subtracting 210 from 240 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
42 can be fit into 300 7 times, resulting in a remainder of 6.
The next digit of our result is 7. 
Result so far: 9352.142857
Deduct 294 from 300 and we're left 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.

Moving on to step 13:
When dividing 60 by 42, we get 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 9352.1428571
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.

On to step 14:
If we divide 180 by 42, we get 4 and a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 9352.14285714
Subtracting 168 from 180 leaves us 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.

The quotient of the division is 9352.14285714, and the remainder is 1.2e-08.
