Let's divide 363849 by 42
Let's see how many times 42 fits into 363849.

On to step 1:
When dividing 3 by 42, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 42

Let's proceed to step 2:
If we divide 36 by 42, we get 0 and a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Take the next digit (3) from the dividend and append it to 36, then repeat: 363 / 42

Advancing to step 3:
42 goes into 363 8 times with a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 336 from 363 to get 27.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 42

Let's proceed to step 4:
42 goes into 278 6 times with a remainder of 26.
The next digit of our result is 6. 
Result so far: 86.0
Subtract 252 from 278 to get 26.
Append the next digit (4) from the dividend to 26 and continue with: 264 / 42

Step 5:
If we divide 264 by 42, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 866.0
Deduct 252 from 264 and we're left with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 42

Moving on to step 6:
When dividing 129 by 42, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 8663.0
If we subtract 126 from 129, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
30 divided by 42 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 8663.0
If we subtract 0 from 30, 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.

Step 8:
300 divided by 42 is 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 8663.07
If we take 294 away from 300, 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.

On to step 9:
If we divide 60 by 42, we get 1 and a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 8663.071
Deduct 42 from 60 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.

Step 10:
If we divide 180 by 42, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 8663.0714
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.

Advancing to step 11:
42 goes into 120 2 times with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 8663.07142
Deduct 84 from 120 and we're left 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 12:
42 can be fit into 360 8 times, resulting in a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 8663.071428
If we take 336 away from 360, we end up 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.

Let's proceed to step 13:
42 goes into 240 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 8663.0714285
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.

On to step 14:
42 goes into 300 7 times with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 8663.07142857
Subtracting 294 from 300 leaves us 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.

The final result is 8663.07142857 with a remainder of 6e-09.
