Let's divide 774255 by 42
We're looking to find how many times 42 goes into 774255.

Step 1:
7 divided by 42 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 42

Moving on to step 2:
42 can be fit into 77 1 times, resulting in a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 42 away from 77, we end up with 35.
Fetch the next digit (4) from the dividend, attach it to 35 and continue: 354 / 42

Moving on to step 3:
354 divided by 42 is 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtract 336 from 354 to get 18.
Bring next digit (2) of the dividend behind the 18 and repeat the process: 182 / 42

Step 4:
If we divide 182 by 42, we get 4 and a remainder of 14.
The next digit of our result is 4. 
Result so far: 184.0
If we subtract 168 from 182, we get 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 42

Step 5:
42 can be fit into 145 3 times, resulting in a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 1843.0
Subtract 126 from 145 to get 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 42

Advancing to step 6:
42 goes into 195 4 times with a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 18434.0
Deduct 168 from 195 and we're left 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.

Let's proceed to step 7:
When dividing 270 by 42, we get 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 18434.6
Deduct 252 from 270 and we're left 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.

Going ahead to step 8:
42 goes into 180 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 18434.64
If we subtract 168 from 180, we 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.

On 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: 18434.642
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.

Advancing to step 10:
360 divided by 42 is 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 18434.6428
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 18434.64285
If we subtract 210 from 240, we 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.

Let's proceed to step 12:
42 goes into 300 7 times with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 18434.642857
If we subtract 294 from 300, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
When dividing 60 by 42, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 18434.6428571
If we take 42 away from 60, we end up 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.

Step 14:
The number 42 fits into 180 4 times, leaving a remainder of 12.
The next digit of our result is 4. 
Result so far: 18434.64285714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 18434.64285714 and a remainder of 1.2e-08.
