868041 ÷ 42 
Our goal is to divide 868041 by 42.

On to step 1:
42 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 42

Advancing to step 2:
86 divided by 42 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 2 after subtracting 84 from 86.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 42

Going ahead to step 3:
When dividing 28 by 42, we get 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we take 0 away from 28, we end up with 28.
Append the next digit (0) from the dividend to 28 and continue with: 280 / 42

Going ahead to step 4:
If we divide 280 by 42, we get 6 and a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 206.0
The remainder is 28 after subtracting 252 from 280.
Fetch the next digit (4) from the dividend, attach it to 28 and continue: 284 / 42

Moving on to step 5:
The number 42 fits into 284 6 times, leaving a remainder of 32.
The next digit of our result is 6. 
Result so far: 2066.0
Subtracting 252 from 284 leaves us with 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 42

Let's proceed to step 6:
If we divide 321 by 42, we get 7 and a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 20667.0
If we take 294 away from 321, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
42 goes into 270 6 times with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 20667.6
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:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 20667.64
Subtracting 168 from 180 leaves us 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.

Going ahead to step 9:
42 goes into 120 2 times with a remainder of 36.
The next digit of our result is 2. 
Result so far: 20667.642
If we take 84 away from 120, we end up with 36.
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.
The number 8 becomes the next digit in our result. 
Result so far: 20667.6428
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
42 can be fit into 240 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 20667.64285
Deduct 210 from 240 and we're left 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.

Advancing to step 12:
42 goes into 300 7 times with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 20667.642857
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 13:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 20667.6428571
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.

Advancing 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: 20667.64285714
Subtracting 168 from 180 leaves us 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.

The final result is 20667.64285714 with a remainder of 1.2e-08.
