868089 ÷ 42 
Let's see how many times 42 fits into 868089.

Moving on to step 1:
8 divided by 42 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 42

Going ahead to step 2:
When dividing 86 by 42, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 84 from 86 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 42

Let's proceed to step 3:
If we divide 28 by 42, we get 0 and a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 28 and we're left with 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 42

Step 4:
If we divide 280 by 42, we get 6 and a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 206.0
If we take 252 away from 280, we end up with 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 42

Going ahead to step 5:
288 divided by 42 is 6 with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 2066.0
The remainder is 36 after subtracting 252 from 288.
Append the next digit (9) from the dividend to 36 and continue with: 369 / 42

Going ahead to step 6:
369 divided by 42 is 8 with a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 20668.0
Deduct 336 from 369 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 7:
42 can be fit into 330 7 times, resulting in a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 20668.7
Subtract 294 from 330 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.

Advancing to step 8:
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: 20668.78
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.

Advancing to step 9:
If we divide 240 by 42, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 20668.785
Subtract 210 from 240 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
The number 42 fits into 300 7 times, leaving a remainder of 6.
The next digit of our result is 7. 
Result so far: 20668.7857
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 11:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 20668.78571
Subtract 42 from 60 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.

Step 12:
If we divide 180 by 42, we get 4 and a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 20668.785714
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.

Advancing to step 13:
120 divided by 42 is 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 20668.7857142
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.

Step 14:
42 goes into 360 8 times with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 20668.78571428
Subtracting 336 from 360 leaves us 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.

The final outcome is 20668.78571428, with a leftover of 2.4e-08.
