We look at the division of 960021 by 42 
Let's see how many times 42 fits into 960021.

Advancing to step 1:
If we divide 9 by 42, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 42

Going ahead to step 2:
96 divided by 42 is 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 84 from 96, we get 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 42

Moving on to step 3:
120 divided by 42 is 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we take 84 away from 120, we end up with 36.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 42

On to step 4:
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: 228.0
The remainder is 24 after subtracting 336 from 360.
Take the next digit (2) from the dividend and append it to 24, then repeat: 242 / 42

Step 5:
42 can be fit into 242 5 times, resulting in a remainder of 32.
The next digit of our result is 5. 
Result so far: 2285.0
If we take 210 away from 242, we end up with 32.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 42

Let's proceed to step 6:
321 divided by 42 is 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 22857.0
Subtract 294 from 321 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
42 goes into 270 6 times with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 22857.6
The remainder is 18 after subtracting 252 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 22857.64
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.

Moving on to step 9:
The number 42 fits into 120 2 times, leaving a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 22857.642
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
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: 22857.6428
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.

Going ahead to step 11:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 22857.64285
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.

Moving on to step 12:
If we divide 300 by 42, we get 7 and a remainder of 6.
The next digit of our result is 7. 
Result so far: 22857.642857
The remainder is 6 after subtracting 294 from 300.
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.
The number 1 becomes the next digit in our result. 
Result so far: 22857.6428571
Subtracting 42 from 60 leaves us with 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 14:
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: 22857.64285714
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.

The final outcome is 22857.64285714, with a leftover of 1.2e-08.
