Let's divide 663333 by 42
We want to divide 663333 by 42.

Step 1:
42 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 42

On to step 2:
When dividing 66 by 42, we get 1 with a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 42 away from 66, we end up with 24.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 42

Let's proceed to step 3:
When dividing 243 by 42, we get 5 with a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 210 away from 243, we end up with 33.
Include the next digit (3) from the dividend after 33, then repeat: 333 / 42

On to step 4:
42 can be fit into 333 7 times, resulting in a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 157.0
Deduct 294 from 333 and we're left with 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 42

On to step 5:
The number 42 fits into 393 9 times, leaving a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 1579.0
If we subtract 378 from 393, we get 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 42

Advancing to step 6:
If we divide 153 by 42, we get 3 and a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 15793.0
The remainder is 27 after subtracting 126 from 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
42 can be fit into 270 6 times, resulting in a remainder of 18.
The next digit of our result is 6. 
Result so far: 15793.6
Subtracting 252 from 270 leaves us 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: 15793.64
Subtracting 168 from 180 leaves us 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.

Let's proceed to step 9:
42 can be fit into 120 2 times, resulting in a remainder of 36.
The next digit of our result is 2. 
Result so far: 15793.642
Subtract 84 from 120 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.

Going ahead to step 10:
360 divided by 42 is 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 15793.6428
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.

On 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: 15793.64285
Subtracting 210 from 240 leaves us with 30.
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:
When dividing 300 by 42, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 15793.642857
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.

Let's proceed to step 13:
When dividing 60 by 42, we get 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 15793.6428571
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.

Moving on to step 14:
If we divide 180 by 42, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 15793.64285714
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.

The final outcome is 15793.64285714, with a leftover of 1.2e-08.
