971856 ÷ 42 
We're looking to find how many times 42 goes into 971856.

Going ahead to step 1:
9 divided by 42 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 42

Let's proceed to step 2:
97 divided by 42 is 2 with a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 84 away from 97, we end up with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 42

Going ahead to step 3:
The number 42 fits into 131 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtracting 126 from 131 leaves us with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 42

Advancing to step 4:
The number 42 fits into 58 1 times, leaving a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 231.0
The remainder is 16 after subtracting 42 from 58.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 42

Going ahead to step 5:
The number 42 fits into 165 3 times, leaving a remainder of 39.
The next digit of our result is 3. 
Result so far: 2313.0
Deduct 126 from 165 and we're left with 39.
Append the next digit (6) from the dividend to 39 and continue with: 396 / 42

Step 6:
The number 42 fits into 396 9 times, leaving a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 23139.0
Subtract 378 from 396 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.

Let's proceed to step 7:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 23139.4
Subtract 168 from 180 to 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.

On to step 8:
If we divide 120 by 42, we get 2 and a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 23139.42
Subtract 84 from 120 to 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.

Step 9:
When dividing 360 by 42, we get 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 23139.428
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
240 divided by 42 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 23139.4285
If we take 210 away from 240, we end up 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.

On to step 11:
When dividing 300 by 42, we get 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 23139.42857
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 12:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 23139.428571
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.

Let's proceed to step 13:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 23139.4285714
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.

Step 14:
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: 23139.42857142
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.

The final result is 23139.42857142 with a remainder of 3.6e-08.
