842668 divided by 42 
We're looking to find how many times 42 goes into 842668.

Advancing to step 1:
If we divide 8 by 42, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 42

Let's proceed to step 2:
When dividing 84 by 42, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 84 from 84 leaves us with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 42

Step 3:
42 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 42

Step 4:
26 divided by 42 is 0 with a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 200.0
The remainder is 26 after subtracting 0 from 26.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 42

Going ahead to step 5:
266 divided by 42 is 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 2006.0
Subtracting 252 from 266 leaves us with 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 42

Let's proceed to step 6:
The number 42 fits into 148 3 times, leaving a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 20063.0
The remainder is 22 after subtracting 126 from 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
42 goes into 220 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 20063.5
If we subtract 210 from 220, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
42 goes into 100 2 times with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 20063.52
The remainder is 16 after subtracting 84 from 100.
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 9:
160 divided by 42 is 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 20063.523
Subtract 126 from 160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 20063.5238
The remainder is 4 after subtracting 336 from 340.
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 11:
42 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 20063.5238
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
42 can be fit into 400 9 times, resulting in a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 20063.523809
Deduct 378 from 400 and we're left 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.

Advancing to step 13:
42 can be fit into 220 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 20063.5238095
If we take 210 away from 220, we end up 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.

On to step 14:
100 divided by 42 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 20063.52380952
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 20063.52380952, with a leftover of 1.6e-08.
