Let's divide 841309 by 42
We want to figure out the number of times 841309 can be divided by 42.

On to step 1:
42 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 42

Let's proceed to step 2:
The number 42 fits into 84 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 0 after subtracting 84 from 84.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 42

Step 3:
1 divided by 42 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 20.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 42

Going ahead to step 4:
42 goes into 13 0 times with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 200.0
Deduct 0 from 13 and we're left with 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 42

Going ahead to step 5:
If we divide 130 by 42, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 2003.0
Subtracting 126 from 130 leaves us with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 42

Moving on to step 6:
42 can be fit into 49 1 times, resulting in a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 20031.0
Subtracting 42 from 49 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
The number 42 fits into 70 1 times, leaving a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 20031.1
Subtract 42 from 70 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
42 can be fit into 280 6 times, resulting in a remainder of 28.
The next digit of our result is 6. 
Result so far: 20031.16
The remainder is 28 after subtracting 252 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
When dividing 280 by 42, we get 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 20031.166
Deduct 252 from 280 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 20031.166 and a remainder of 0.0028.
