865374 divided by 42 
Our goal is to divide 865374 by 42.

Moving on to step 1:
8 divided by 42 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 42

Advancing to step 2:
42 goes into 86 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 84 away from 86, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 42

Going ahead to step 3:
25 divided by 42 is 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtracting 0 from 25 leaves us with 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 42

Moving on to step 4:
If we divide 253 by 42, we get 6 and a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 206.0
If we take 252 away from 253, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 42

Let's proceed to step 5:
42 goes into 17 0 times with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 2060.0
If we subtract 0 from 17, we get 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 42

Going ahead to step 6:
174 divided by 42 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 20604.0
If we take 168 away from 174, we end up 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.

Advancing to step 7:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 20604.1
The remainder is 18 after subtracting 42 from 60.
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 8:
When dividing 180 by 42, we get 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 20604.14
If we take 168 away from 180, we end up 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:
When dividing 120 by 42, we get 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 20604.142
If we subtract 84 from 120, we 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.

Moving on to step 10:
If we divide 360 by 42, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 20604.1428
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.

Advancing to step 11:
When dividing 240 by 42, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 20604.14285
The remainder is 30 after subtracting 210 from 240.
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.
Record the quotient 7 as the next digit in the result. 
Result so far: 20604.142857
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.

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: 20604.1428571
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.

Moving on to step 14:
When dividing 180 by 42, we get 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 20604.14285714
If we take 168 away from 180, we end up 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 outcome is 20604.14285714, with a leftover of 1.2e-08.
