We divide 392971 by 42
We want to figure out the number of times 392971 can be divided by 42.

Step 1:
The number 42 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 42

Going ahead to step 2:
39 divided by 42 is 0 with 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.
Include the next digit (2) from the dividend after 39, then repeat: 392 / 42

Moving on to step 3:
42 goes into 392 9 times with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 378 away from 392, we end up with 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 42

On to step 4:
42 goes into 149 3 times with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 93.0
Deduct 126 from 149 and we're left with 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 42

Let's proceed to step 5:
The number 42 fits into 237 5 times, leaving a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 935.0
Deduct 210 from 237 and we're left with 27.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 42

On to step 6:
If we divide 271 by 42, we get 6 and a remainder of 19.
The next digit of our result is 6. 
Result so far: 9356.0
If we take 252 away from 271, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
The number 42 fits into 190 4 times, leaving a remainder of 22.
The next digit of our result is 4. 
Result so far: 9356.4
If we take 168 away from 190, we end up 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.

Let's proceed to step 8:
42 goes into 220 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 9356.45
The remainder is 10 after subtracting 210 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
When dividing 100 by 42, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 9356.452
If we take 84 away from 100, we end up 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 10:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 9356.4523
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.

Let's proceed to step 11:
When dividing 340 by 42, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 9356.45238
Deduct 336 from 340 and we're left with 4.
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 12:
42 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 9356.45238
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.

Moving on to step 13:
42 goes into 400 9 times with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 9356.4523809
Subtracting 378 from 400 leaves us 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.

Let's proceed to step 14:
The number 42 fits into 220 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 9356.45238095
Deduct 210 from 220 and we're left 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.

The final result is 9356.45238095 with a remainder of 1e-08.
