We divide 336690 by 42
We're looking to find how many times 42 goes into 336690.

Advancing to step 1:
42 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 42

On to step 2:
If we divide 33 by 42, we get 0 and a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Include the next digit (6) from the dividend after 33, then repeat: 336 / 42

Advancing to step 3:
42 goes into 336 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 336 from 336, we get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 42

Advancing to step 4:
42 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 80.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 42

On to step 5:
42 goes into 69 1 times with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 801.0
If we subtract 42 from 69, we get 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 42

On to step 6:
42 goes into 270 6 times with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 8016.0
If we take 252 away from 270, 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.

Moving on to step 7:
The number 42 fits into 180 4 times, leaving a remainder of 12.
The next digit of our result is 4. 
Result so far: 8016.4
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.

Let's proceed to step 8:
If we divide 120 by 42, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 8016.42
Subtracting 84 from 120 leaves us 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 9:
When dividing 360 by 42, we get 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 8016.428
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.

Moving on to step 10:
42 can be fit into 240 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 8016.4285
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.

Let's proceed to step 11:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 8016.42857
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.

Step 12:
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: 8016.428571
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.

Let's proceed to step 13:
If we divide 180 by 42, we get 4 and a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 8016.4285714
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 14:
The number 42 fits into 120 2 times, leaving a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 8016.42857142
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.

The final outcome is 8016.42857142, with a leftover of 3.6e-08.
