392594 ÷ 42 
Let's see how many times 42 fits into 392594.

Going ahead 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
Deduct 0 from 3 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 42

Moving on to step 2:
42 can be fit into 39 0 times, resulting in a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 42

Moving on to step 3:
The number 42 fits into 392 9 times, leaving a remainder of 14.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 378 from 392 and we're left with 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 42

Step 4:
If we divide 145 by 42, we get 3 and a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
If we subtract 126 from 145, we get 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 42

Step 5:
When dividing 199 by 42, we get 4 with a remainder of 31.
Use 4 as the next digit of our solution. 
Result so far: 934.0
Deduct 168 from 199 and we're left with 31.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 42

Going ahead to step 6:
42 goes into 314 7 times with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 9347.0
Subtracting 294 from 314 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
42 goes into 200 4 times with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 9347.4
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
When dividing 320 by 42, we get 7 with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 9347.47
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
42 can be fit into 260 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 9347.476
Subtracting 252 from 260 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
42 goes into 80 1 times with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 9347.4761
The remainder is 38 after subtracting 42 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 11:
380 divided by 42 is 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 9347.47619
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
If we divide 20 by 42, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 9347.47619
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
42 goes into 200 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 9347.4761904
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
42 can be fit into 320 7 times, resulting in a remainder of 26.
The next digit of our result is 7. 
Result so far: 9347.47619047
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 9347.47619047 and a remainder of 2.6e-08.
